                What are NFA Weapons?  
                
                      There are two kinds of firearms
                under U.S. (federal) law,
                title 1 firearms and title 2.  Title 1 firearms are long
                guns
                (rifles and shotguns), handguns, firearm frames or receivers,
                and
                most NFA weapons are also title 1 firearms.  Title 2
                weapons are
                NFA weapons.  Title 2 of the 1968 Gun Control Act is the
                National
                Firearms Act (26 USC sec. 5801 et seq.), hence NFA.  Title
                1 is
                generally called the Gun Control Act, (18 USC sec. 921 et seq.).
                
                NFA weapons are sometimes called class 3 weapons, because a
                class
                3 SOT (see below) is needed to deal in NFA weapons. 
                 
                     These weapons may also be further
                regulated by states or
                localities, and while these weapons can be legally owned under
                federal law, some states and localities further regulate
                ownership or prohibit it (see below).   The NFA Branch
                of ATF
                administers the National Firearms Registration and Transfer
                Record, which necessarily encompasses most of the NFA
                regulation.
                
                     NFA weapons are: machine guns, sound
                suppressors (a.k.a.
                silencers), short barreled shotguns, short barreled rifles,
                destructive devices and "any other weapons". A machine
                gun is any
                gun that can fire more than one shot with a single pull of the
                trigger, or a receiver of a machine gun, or a combination of
                parts for assembling a machine gun, or a part or set of parts
                for
                converting a gun into a machine gun.  A silencer is any
                device
                for muffling the gunshot of a portable firearm, or any part
                exclusively designed or intended for such a device (see
                discussion below).  A short barreled shotgun is any shotgun
                (shoulder fired, smooth bore)  with a barrel of less than
                18" or
                an overall length of less than 26", or any weapon made from
                a
                shotgun falling into the same length  parameters.  A
                short
                barreled rifle is a rifle (shoulder fired, rifled  bore)
                with a
                barrel length of less than 16", or an overall length
                of  less
                than 26", or any weapon made from a rifle falling into the
                same
                length parameters (like a pistol made from a rifle).  In
                measuring barrel length you do it from the closed breech to the
                muzzle, see 27 CFR sec. 179.11.  To measure overall length
                do so
                along, "the distance between the extreme ends of the weapon
                measured along a line parallel to the center line of the
                bore." 
                27 CFR sec. 179.11.  On a folding stock weapon you measure
                with
                the stock extended, provided the stock is not readily
                detachable,
                and the weapon is meant to be fired from the shoulder.  A
                destructive device (DD) is a explosive, incendiary or poison gas
                weapon, or any firearm with a bore over 1/2", with
                exceptions for
                sporting shotguns, among other things (see discussion
                below).  
                Any other weapons (AOW's) are a number of things; smooth bore
                pistols, any pistol with more than one grip,(but see below)
                gadget type guns (cane gun, pen gun) and shoulder fired weapons
                with both rifled and smooth bore barrels between 12" and
                18",
                that must be manually reloaded (see discussion below). 
                These
                definitions are simplified, to see if a specific gun is a title
                1
                or 2 firearm one needs to refer to the specific definition under
                the statute(s), and possibly consult with the Technology Branch
                of ATF.   There is also case law on the issue of
                whether a 
                specific item falls into one of these categories. 
                
                Owning or making an NFA weapon
                
                     It is illegal for anyone to have
                possession of an NFA weapon
                that is not registered to them in the NFA Registry.  
                It is also
                not possible for anyone, except government entities, to register
                an
                existing NFA weapon that is not registered, except immediately
                after one is made by a class 2 NFA manufacturer.  An
                individual 
                otherwise able to own any gun under federal law can receive and
                own any NFA weapon (local law permitting, ATF cannot approve a
                transfer  where federal, state or local law would be
                violated by
                the transferee possessing the weapon in question, see 26 USC
                sec.
                5812(a)(6)) on a Form 4, "Application for Tax Paid Transfer
                and
                Registration of Firearm".  Non-FFL holders may 
                only purchase an
                NFA weapon from a dealer or individual within their own 
                state. 
                If the weapon is located out of state it must be transferred to
                a 
                class 3 dealer within the state, before transfer to the non FFL
                purchaser.   C&R FFL holders (type 03) may
                purchase C&R NFA guns
                from out of state  dealers and individuals.  Type 01
                FFL holders
                may purchase any fully  transferrable (no dealer samples,
                see
                below) NFA weapon, from  an out of state source. If the FFL
                holder is an individual he must submit  fingerprints,
                photograph,
                and the law enforcement certification.
                
                     The transfer involves paying the
                transfer tax, which is $200
                for  all the NFA weapons, except AOW's for which the tax is
                a
                mere $5.  Individuals also have to get one of several
                specified
                local chief law enforcement officers to sign the form (see the
                section on the law enforcement certification for more
                information), submit their fingerprints in duplicate, and attach
                photos of the transferee to the form.   While the
                transfer tax is
                levied by law on the transferor (seller), in practice the
                transferee (buyer) is expected to pay the tax.  Transfers
                to
                individuals tend to take at least 4 months, although subsequent
                transfers can be quicker. 
                
                     Or you can make any NFA weapon, except
                for machine guns (see
                below), by filing a Form 1, "Application to Make and
                Register a 
                Firearm", and paying the $200 making tax, which applies to
                all of
                these  weapons, including AOW's.  You may not make the
                proposed
                weapon until  the Form 1 is returned to you approved. 
                The law
                enforcement certification,  photos and fingerprints also
                apply to
                Form 1's, and in fact to any transaction to an individual. 
                Additionally the manufacturer of any NFA weapon,  including
                an
                individual making one on a Form 1 must mark the receiver of the
                weapon with the maker's name and city and state.  NFA
                Branch can
                grant exemptions from this for DD's.  All types of
                corporations,
                including  corporate type 01 FFL holders, need not do the
                certification, photo  and fingerprint
                requirements.   Any of the
                forms listed, and the  fingerprint cards, are available for
                free
                from ATF, either in Washington, D.C. or your local office.
                
                     The original of the paperwork,
                particularly any that have
                tax stamps on them (Form 1 or 4) should be kept in a safe place.
                
                ATF can demand to see the form (see below on your 4th amendment
                rights).  On a tax paid transfer, ATF puts a tax stamp,
                like a
                postage stamp (or like the one that caused the American
                colonists
                to take up arms), on the document.  You paid $200 (or $5)
                for it,
                and it is worth that.  It is unwise to lose the original
                form.  
                They should be kept in a safe deposit box.  Tax exempt
                forms
                (Form 2, 3, 5, 6, 10) have no tax stamp, and a copy of the form
                from ATF, should the original be lost, will be fine.  ATF
                can
                give you a new tax stamp should you lose one, but expect a hard
                time, and they have discretion in doing it.   It is
                not unheard
                of for ATF to have no record in their computer of a weapon
                registered to you.  The paperwork can avoid a lot of
                hassles.  
                Additionally, if the gun in question is a machine gun, not
                having
                the paperwork can lead to being charged with a violation of 18
                USC sec. 922(o).  A federal circuit court of appeals has
                ruled
                (U.S. v. Just, 74 F.3d 902 (8th Cir.  1996)) that sec.
                922(o)
                prohibits possessing all machine guns, and it is an affirmative
                defense to such a charge that the weapon was legally possessed
                before it took effect.  It is up to the defendant to prove
                such a
                defense, but usually by a lower evidentiary standard than the
                government needs to prove to show a criminal violation 
                (usually
                preponderance of the evidence versus beyond a reasonable 
                doubt). 
                It is not up to the government to prove the weapon was  not
                registered, for a charge under sec. 922(o).  If you don't
                have
                the paperwork, and it isn't in ATF's computer, (it is likely
                they
                will check, even though they don't have to prove non-
                registration, they don't want someone to wave a registration
                form
                in their face during a trial) you can have a serious problem. 
                
                Taxpayer privacy
                  
                     The transfer paperwork is nominally a
                tax return; the
                purpose of the registration, and the National Firearms
                Registration and Transfer Record (Registry) is keeping track of
                who owes the tax.  ATF takes the position that taxpayer
                privacy
                laws apply to a transfer form, and that they may not discuss a
                pending transfer with anyone but the taxpayer, who is the
                transferor (seller), as he is responsible for the tax by law. 
                This also serves to allow ATF to refuse to discuss why a
                transfer
                is taking so long with the party who is most interested in that
                question, the transferee (buyer).  The NFA also prohibits
                the use
                of the Registry information for any law enforcement purpose
                except prosecutions for making a false statement on a transfer
                form (26 USC sec. 5848).   Other tax laws prohibit the
                release of
                transfer information, as a tax return, except for certain narrow
                public safety type circumstances.   See 26 USC sec.
                6103, for
                example. 
                
                     However, as most NFA weapons are also
                regulated by the GCA,
                purchases from a dealer require the completion of the standard
                4473 yellow form, as well as dealer bound book records, and this
                source of information is not so similarly
                restricted.   ATF may
                release this information to local law enforcement for a host of
                law enforcement purposes.  (18 USC sec. 923(g)(1)(D)).
                
                Tax exemptions
                
                     Law enforcement, states, and local
                governments are totally
                exempt from the making and transfer (either to or from) taxes,
                but must comply with the registration requirements. 
                Federal
                government agencies, military, and National Guard need not
                comply
                with the registration or tax requirements.
                
                    There is no tax on transfers to anyone of a
                weapon that is 
                unserviceable.  Making a weapon unserviceable means it is
                permanently  altered so that it cannot work, and is not
                readily
                restorable.  For  example a gun can be made
                unserviceable by
                welding the chamber closed,  and welding the barrel to the
                receiver or frame.  An unserviceable weapon  is
                sometimes called
                a DEWAT, for DE-activated WAr Trophy (see below). 
                
                     There is no tax on a transfer to a
                lawful heir from the
                owner's estate.  Lawful heir just means someone named in a
                will
                to get the weapons, or a person entitled to inherit under the
                applicable intestacy laws if there  was no will, or the
                will did
                not apply.  The heir must be able to own the  weapon
                under state
                and federal laws.  The heir will have to do all the
                other  steps
                of a transfer to an individual.  Unless the heir is a class
                3 he
                may  not inherit post-86 machine guns (and would also need
                the
                police demo letter, see below).  I am unsure about a
                non-class 3
                inheriting pre-86 samples (see  below).   A
                weapon to an heir may
                also be transferred interstate, if need be; the gun need not be
                transferred to a dealer in the heir's state, if the 
                deceased
                owner resided in another
                state.         
                
                     Special (Occupational) Taxpayers (SOT)
                under the NFA are
                exempt from some of the making or transfer taxes.  All SOT
                holders may transfer weapons between themselves tax free.  
                However a transfer between an individual and a SOT will require
                the tax.  And unless one has a class 2 SOT, there is a tax
                on
                making an NFA weapon, except for making by or on behalf of a
                government entity. SOT's need not get the law enforcement
                certification for any transfer, except DD's (unless they have
                the
                appropriate FFL), even for their own personal collection,
                although in that case they should pay the $200 transfer
                tax.   They
                also need not attach a photo to the transfer paperwork, nor
                submit fingerprints.  The Crime Bill (9/14/94) now requires
                
                these things with FFL applications, and SOT applications,
                however, and ATF was requiring them even before that
                became  law,
                since early 1994.   If one plans to engage in 
                business in NFA
                weapons, one needs to be a SOT, just as one needs the FFL if
                they
                plan to engage in the business with regular firearms or
                ammunition.
                
                                   
                The classes of SOT holders 
                1 - importer of NFA firearms 
                2 - manufacturer of NFA firearms 
                3 - dealer in NFA firearms 
                
                    A class 1 or 2 SOT may also deal in NFA
                firearms.  A class 3
                SOT costs $500 a year, due each July 1.   A class 1 or
                2 SOT
                costs $1000 a year,  except that SOT's who did less than
                $500,000
                in gross receipts in business the previous year qualify 
                for a
                reduced rate of $500 per year, also due July 1.  One must
                also
                have the appropriate FFL to engage in the specific activity, as
                well as the SOT. This is because most NFA weapons are also title
                1 weapons, and thus both the law regulating title 1 weapons (the
                GCA) and title 2 weapons (the NFA) must be complied with. 
                As
                with the privacy of Registry information and transfer
                information, SOT status is also protected tax information, and
                ATF will not release lists of SOT holders, as they will of FFL
                holders.
                
                     If you were a Class 2 SOT, and thus a
                manufacturer of NFA
                weapons you could make, tax free, a machine gun, silencer, short
                rifle, short shotgun or AOW.  You could also have weapons
                transferred to you tax free, by other SOT's.   You
                would also
                have to have a type 07 or type 10 FFL.   You would not
                need to
                ask prior permission of ATF to make the weapon, you would notify
                them of its making within 24 hours of its making by filing Form
                2
                with ATF.  You could also import foreign made NFA weapons,
                for
                R&D use (one of each, not a bunch of each model).  To
                import a
                machine gun you would need a  police letter, but for other
                weapons they would be considered pre-86 dealer samples.  To
                import for resale you need a Class 1 SOT.   
                
                     A sole proprietor SOT may keep any NFA
                weapon he has after
                surrendering his SOT, as his personal property, except post-86
                machine guns, discussed below.   If ATF thinks, based
                on the 
                number of weapons retained and the timing, that your SOT status
                was used to evade the transfer taxes, they may demand tax on all
                or some of the guns, although you will be entitled to a credit
                against that for your annual $500 or $1000 SOT tax. 
                
                Special treatment of certain weapons
                
                     Destructive devices are treated
                differently, in terms of
                manufacturing or dealing.  One must have a special FFL,
                (type 9,
                10 or 11, to deal, make or import respectively) and be a SOT to
                make one tax free or deal in them.  But anyone can make
                them on a
                Form 1, tax paid.  
                
                     Machine guns are also treated
                differently.  In 1986, as part
                of the Firearm Owners' Protection Act (FOPA), Congress
                prohibited
                individuals from owning machine guns, and made it an affirmative
                defense  that the machine gun was registered before the act
                took
                effect (which was 5/19/86). See 18 USC sec. 922(o) for the law. 
                Thus as an individual you can only legally own a machine gun
                that
                was registered before that date.  Any registered after that
                date
                can only be owned by SOT's, law enforcement, and government
                entities.  A SOT may not keep these machine guns after
                surrendering his SOT.  In order to transfer one of these
                machine
                guns, the SOT must have a request from an agency able to own one
                for a demonstration.  Or an order from one of those
                agencies to
                buy one.   A class 2 SOT can make machine guns for
                research and
                development purposes, or for sale to dealers as samples, or for
                law enforcement.  These are commonly  called post-86
                machine
                guns.
                
                        On top of the FOPA
                machine gun restrictions, any NFA
                weapon imported into the US after the Gun Control Act took
                effect
                (end of 1968) cannot be transferred to an individual.  See
                26 USC
                sec. 5844.  They  can be transferred to SOT's, without
                any police
                demonstration request, and kept by the SOT after surrendering
                his
                SOT.   These are sometimes called "pre-86
                samples", or "dealer
                samples", although dealer sample can be used to refer to
                either a
                post-86 machine gun or any NFA weapon imported after 1968.
                
                Transporting NFA firearms
                
                     In terms of moving the weapons around,
                the following
                applies.  If you are transporting the weapons within your
                state,
                it is wise to keep a photocopy of the registration paperwork,
                whatever it is, (can be Form 1, 2, 3, 4, 5, or 10, as well as
                other more exotic forms of registration, except you probably
                would never have a gun on a Form 10, unless you were the police,
                in which case no one is likely to hassle you about a gun you
                might have anyway) with the gun.  Federal law does not
                expressly
                require it, but it would be foolish not to have ready proof the
                gun is legal.   Many states do require it, they ban
                all or some
                NFA weapons, and exempt from the ban those possessed in
                compliance with federal law.  In such a state you need the
                federal paperwork to be legal under state law.  If
                you  were a
                SOT you should keep a copy of your proof of being an SOT with
                the
                paperwork when you move the guns around.   But an
                individual who
                surrenders his SOT can still have weapons that will be
                registered
                on a Form 2 or Form 3 legally, so not having a copy of the SOT
                with such paperwork proves nothing.   You need not ask
                ATF for
                permission when you move to a new address within the same state,
                nor must you advise them of your new address. 
                
                     To move weapons between states two
                rules apply.  An
                individual must get permission from ATF to move machine guns,
                short rifles, short shotguns or destructive devices between
                states (or to temporarily export them) before doing so. 
                This
                includes taking them somewhere to shoot them, or when
                moving.  
                There is a form called a 5320.20, and ATF will always approve
                them, and fairly quickly, assuming the purpose (generally
                stated)
                for the movement is legitimate, and the target state allows the
                weapon in question. A type 01 FFL can move weapons (except DD's)
                interstate at will, no permission is needed.  But while
                most
                states that otherwise prohibit some or all NFA weapons have
                exceptions for SOT's, or FFL's, a few do not, and thus the
                person
                must make sure he will not be breaking any laws.  An
                unlicensed
                individual need not ask permission to move AOW's or suppressor's
                interstate, again watch the laws at the target
                state.   Having
                the approved 5320.20 form for a suppressor or AOW can avoid
                hassle while traveling.  Lots of folks who think they know
                something about the NFA don't know you only need permission for
                interstate movement of some NFA weapons.    ATF
                will approve a
                5320.20 for suppressors and AOW's; they will approve a 5320.20
                for an FFL also, even if he doesn't need it by law.  
                ATF will
                also now approve a form 5320.20 for a period of one year,
                covering blanket travel to a specific location, if you travel
                there frequently.    A C&R FFL holder can
                only move C&R NFA guns
                interstate without a 5320.20.  See 18 USC sec. 922(a)(4)
                for the
                law imposing the  5320.20 requirement.
                
                                 
                A lost or stolen NFA firearm
                  
                     A lost or stolen NFA firearm can be a
                real problem.  It can
                be a very expensive loss, as well as endangering the continued
                lawfulness of owning NFA firearms, both at a state and federal
                level.  Contrary to what you might hear, NFA firearms,
                machine
                guns and silencers in particular, are very rare in crime. 
                A
                significant source of such weapons in crime is stolen NFA
                firearms, from law enforcement, the military and civilian
                collectors.   A crime spree with a stolen NFA firearm
                can lead to
                restrictive state or local legislation, as well as local law
                enforcement refusing to continue providing the law enforcement
                certification needed for transfers to individuals. 
                Safeguarding
                NFA firearms is not required, but seems to me to be extremely
                prudent, both to preserve the firearm, as well as its continued
                legal ownership.  Reporting the theft of an NFA weapon to
                law
                enforcement is the only way to even have a chance at recovering
                the gun, and preventing its use (or further use) in crime. 
                I
                think reporting its theft is a good idea.  Below is what is
                required, as opposed to what is a good idea.
                
                     ATF has made up a rule, 27 CFR sec.
                179.141, that requires
                the owner of a lost or stolen NFA weapon to make a report
                "immediately upon discovery" to ATF including the name
                of the
                registered owner, kind of firearm, serial number, model,
                caliber,
                manufacturer, date and place of theft or loss and "complete
                statement of facts and circumstances surrounding such theft or
                loss."  However Congress has passed no law authorizing
                ATF to
                make such a requirement, and at  a 1984 Congressional
                hearing
                then ATF Director Stephen Higgins admitted there is no penalty
                for not complying.  See "Armor Piercing Ammunition and
                the
                Criminal Misuse and Availability of Machineguns and
                Silencers",
                Hearings Before the Subcommittee on Crime of the Committee of
                the
                Judiciary House of Representatives, Ninety-Eighth Congress,
                Second Session, May 17, 24 and June 27, 1984, Serial No. 153,
                G.P.O. 1986, page 129.
                
                     However, if one is a FFL holder, one is
                required by law to
                report the theft or loss to both local law enforcement and ATF. 
                As part of PL 103-322 (Crime Bill) (9/13/1994), 18 U.S.C. sec 
                923(g) was amended to require, "(6) Each licensee shall
                report the theft or
                loss of a firearm from the licensee's inventory or collection
                within 48 hours after the theft or loss is discovered, to the
                Secretary and to the appropriate local authorities."
                
                     ATF has created interim rules to
                implement PL 103-322, and
                they are a little more specific, and a little more onerous:
                
                     27 CFR Sec. 178.39a  Reporting
                theft or loss of firearms.
                
                         Each licensee

                the theft or loss was
                     reported to ATF.
                
                This reporting requirement only applies to FFL holders, that is
                folks licensed by ATF to make, sell, import or collect guns. 
                This does not include folks who just own an NFA weapon. 
                
                Repairing NFA weapons 
                
                    As it is illegal for anyone to have
                possession of an NFA
                firearm  that is not registered to them, getting the guns
                repaired, or worked on, can be a hassle.  There are two
                choices:
                if the gunsmith is in the same state as the registered owner the
                owner can take the gun in, and wait while it is worked
                on.   If
                the owner cannot wait, the gun must be transferred to the
                gunsmith, on a Form 5, and returned to the owner by filing a
                Form
                5 to transfer possession back to the owner.   If one
                wishes to
                have an out-of-state gunsmith work on the gun, even if the owner
                can wait with the gun, the owner must either transfer it to the
                gunsmith, or file the form 5320.20 to move it interstate to the
                gunsmith.   One need not be an SOT  to have NFA
                weapons
                transferred to him for repair.   One does need to have
                a type 01
                FFL to work as a gunsmith though.  NY, in a fit of
                benevolence,
                allows licensed gunsmiths there to receive machine guns for
                repair, when machine gun possession there is otherwise limited
                to
                the police, and manufacturers with government contracts. 
                When
                submitting a Form 5 for repair one checks the "Other"
                box in item
                1, type of transfer, writes in "repair" next to the
                box, and
                submits a letter detailing (generally, e.g. "The purpose of
                this
                transfer is to have the [weapon] refinished.") what is to
                be
                done.   The back of the form, with the certifications
                and
                photograph need not be completed.  The turnaround time on
                Form
                5's for this purpose seems to be at least a month, or a minimum
                wait of two months, to transfer it to the 'smith and back. 
                There
                is no transfer tax.   
                
                Penalties for NFA violations
                
                A violation of the NFA can result in a felony conviction,
                punishable by
                up to ten years in prison, and/or a $250,000 fine.  See 26
                USC sec. 5871.
                The US Sentencing Guidelines ordinarily require prison time,
                even for 
                a first offense, however various mitigating and aggravating
                factors can 
                raise or lower the possible sentence range for a first
                offense.  
                
                The statute of limitations on violations of the  NFA is
                three years,
                with the possibility of extension of that time to six years for
                some
                wilful violations.  See 26 USC sec. 6531.  The statute
                of limitations
                does not begin to run on possession offenses until the
                possession stops.
                As long as you possess the contraband item, you are in danger of
                being
                prosecuted.
                
                In addition any NFA weapon EVER transferred or registered in
                violation
                of the Act is subject to civil forfeiture.   See 26
                USC sec. 5872.  A
                forfeiture proceeding is separate from any criminal prosecution,
                and 
                a resolution of a criminal proceeding in favor of the defendant
                will not
                preclude a forfeiture action.   See U.S. v. One
                Assortment of Eighty-Nine
                Firearms, 465 U.S. 354 (1984).
                
                A violation of 18 USC sec. 922(o) of the GCA can also bring up
                to a ten year
                prison sentence, and or a $250,000 fine.  Again, prison
                time is likely,
                even on a first offense. Using a machine gun or a silencer in a
                crime
                can result in a sentencing enhancement of thirty years, even if
                there
                is no NFA prosecution.   See 18 USC sec. 924.
                
                        In short, these are
                serious penalties.  NFA regs are a pain,
                and in my opinion, contrary to the Constitution.  Ignore
                them,
                and get caught, and you will pay a very high price.
                
                                   
                Additional info sources
                
                     One of my main sources  of
                information is a magazine called
                Machine Gun News.  It is quite good for sorting out the
                intricacies of the law, as well as info on guns, suppressors and
                other NFA stuff.  Well worth a subscription, I think. 
                Costs
                $34.95 for a 1 year subscription (12 issues) from, P.O. Box 459,
                Lake Hamilton AR 71951.  Or call (501) 525-7514.  They
                can take
                your MasterCard or Visa over the phone.   They also
                put out a
                book called the "Machine Gun Dealer's Bible", by Dan
                Shea, for
                $64.95  plus $4 shipping.   
                
                     Another good source of information is
                the ATF publication, 
                "Federal Firearms Regulations Reference Guide" ATF P
                5300.4 
                (10-95).   It contains the GCA, NFA, and the
                regulations
                promulgated under  those laws, as  well as other
                useful
                information.  Unlike the old "Red Book", (this
                has a yellow
                cover), this one has the Crime Bill, and Brady law in it. 
                It
                also has the Brady regulations, and the interim Crime Bill
                regulations. ATF also publishes a compilation of  state
                laws,
                "State Laws and Published Ordinances-Firearms", ATF 
                P 5300.5
                (10/94).  Both are free from ATF.  To get forms, or
                the books,
                you can write to ATF Distribution Center, PO Box 5950,
                Springfield, VA 22150-5950. Or phone them at (703)
                455-7801.  Or
                your local ATF office should be able to supply them also.

                GETTING THE LAW ENFORCEMENT CERTIFICATION  
                
                     There are several solutions to the law
                enforcement
                certification problem.  They all require persistence, but
                less
                work than being a legitimate NFA dealer, in my opinion. 
                Becoming
                a class 3  dealer is one solution though.  
                Another solution is
                to be incorporated.  If you are a professional and are
                already
                incorporated for your job (doctor, lawyer) your corporation can
                buy NFA weapons, and the photo, police signoff and fingerprints
                are not needed.  Just a Form 4.   The corporation
                might be buying
                weapons for an investment, or for security, or for another good
                reason.  You could incorporate yourself just to get NFA
                weapons
                also, although you should talk to a lawyer or another
                knowledgeable person about the downsides of being incorporated
                before just doing it.  As the weapons are registered to the
                company, and not the owner of the company, they will have to be
                transferred out, tax paid (unless they are going to a government
                entity), if the corporation is ever dissolved.  As
                corporate
                assets, creditors might get them in the event of bankruptcy of
                the corporation, or a judgment against the corporation.  
                In my opinion the best thing is to have the
                weapons owned and registered to the person who actually owns
                them, and not an intermediary.  I also am aware that in
                some
                areas  of the country the incorporation route may be the
                only way
                to own NFA weapons, as a practical matter.
                
                        Pretending you live
                in a jurisdiction where the CLEO will 
                sign, when you do not, may be tempting, but cannot be
                recommended.
                ATF has prosecuted for this, claiming that putting a bogus
                address on the
                form is submitting false information to the feds, in violation
                of 26 USC 5861(l).  See U.S. v. Muntean, 870 F.Supp 261 (N.D.Ind.
                
                1994), for a case of such a prosecution.   While you
                may have addresses
                in several places, if you do not think you can make a credible
                case that you live there (do you sleep there?  Have a
                phone?
                Utilities?) I think it is unwise to tell ATF you reside there,
                for purposes of a transfer form. 
                
                     However, the below process is what the
                law and ATF
                regulations contemplate as the way to get a signoff, if you need
                one.  
                
                     Step 1:  You ask the following
                persons if they would sign;
                the local chief of police, the local sheriff, the local district
                (prosecuting) attorney, the chief of the state police, and the
                state Attorney General. The CLEO can delegate the signing duty,
                for his convenience.  Insist they refuse in writing, if
                that is
                what they will do.  You may be surprised, one might
                sign.  Assume
                they all refuse.  That list of persons comes from 27 CFR
                sec.
                179.85, which is the regulation that created the law enforcement
                certification requirement for Form 4's.  27 CFR sec. 179.63
                is
                the companion regulation for Form 1's.  It is NOT in any
                statute
                passed by Congress.  Although not listed, and ATF will NOT
                designate federal officials as also acceptable (see below) other
                persons whose certification has been acceptable in the recent
                past include; local U.S. Attorney's, local federal judges, local
                U.S. Marshals,  and local F.B.I. agents.  Other local
                federal law
                enforcement agents might also work, like DEA or ATF (imagine
                accepting their own certification!) or Secret Service.  The
                federal law enforcement agents should probably be in a
                supervisory capacity, like the head of the field office or
                similar post.  
                
                      It is helpful, in general, to
                quote the certification text,
                that  is what you are asking them to certify.  For a
                Form 4 it
                reads,  "I certify that I am the chief law enforcement
                officer of
                the organization  named below having jurisdiction in the
                area of
                residence of (name of  transferee).  I have no
                information that
                the transferee will use the  firearm or device described on
                this
                application for other than lawful purposes.  I have no
                information indicating that the receipt and/or possession of the
                firearm described in item 4 of this form would place the
                transferee in violation of State or local law."
                
                     Step 2:  Copy the refusal letters,
                and send the copies to
                the NFA Branch of ATF.   Ask them to designate other
                persons
                whose signature would be acceptable, as the ones listed in the
                regulation would not sign.  They are required to do this by
                the
                same regulation, it is the safety valve for when none of the
                designated persons will sign.  ATF will almost certainly
                say that
                they will accept the certification of a state judge who has
                jurisdiction over where you live (same as the chief, D.A. and
                sheriff in step 1, they have to have jurisdiction over where you
                live) and who is a judge of a court of general jurisdiction,
                that
                is a trial court that can (by law) hear any civil or criminal
                case.  No limit as to dollar amount in civil cases, or type
                of
                crime in criminal cases.  No small claims court or traffic
                court
                type judges, in other words.  Let's assume they
                refuse.  
                
                     Step 3: get back to ATF, Send them
                copies of the rejection
                letters, and ask that they accept a letter of police clearance,
                or a police letter saying you have no criminal record/history
                with them, in lieu of the certification, together with your
                certification that you are OK, and that the weapon would be
                legal
                for you to have where you live. They will either respond OK, or
                with more persons to try.  If you reach the point where
                they will
                not accept the police clearance letter, and not designate
                someone
                who has not turned you down, you can sue, if the certification
                is
                for a Form 1, or the transferor (seller) on a Form 4 can sue. 
                
                     There are two cases on this issue. The
                first is Steele v.
                NFA Branch, 755 F.2d 1410 (11th Cir. 1985), where the 11th
                circuit federal appeals court said a person trying to transfer a
                gun to one who was otherwise eligible to own the gun, but could
                not get the certification from anyone acceptable to ATF, could
                sue to force the transfer without it.  In the case Steele
                (the
                transferor in a Form 4 transfer) had not asked  everyone
                acceptable to ATF, as well as not alleged, as part of his case,
                that the potential transferee was otherwise eligible by law to
                own the weapon, and the case was disposed of on those grounds. 
                Note that the version of the regulation creating the
                certification requirement, reproduced in the footnotes of this
                case, has a different list of acceptable persons.  After
                some
                were sued in connection with this case, all the federal law
                enforcement officials were removed from the regulation. 
                Correspondence from ATF indicates they will not designate any
                federal officials as other acceptable persons either.  The
                Steele
                decision was followed in the case Westfall v. Miller, 77 F.3d
                868
                (5th Cir. 1996), in which a transferee, not transferor, sued
                over
                non-approval of a Form 4 without the certification.  Again
                Westfall did not ask everyone listed in the regulation. 
                Again
                his case was thrown out for lack of standing. The court said
                they
                could not tell if the reason he couldn't get the gun was an
                illegal requirement, the signoff, or his own failure to try and
                get a signoff. 
                
                    This certification is not really a big deal
                for the chief law
                enforcement officer (CLEO) making it, and it DOES NOT expressly 
                make the CLEO legally responsible for the weapon or your use of
                it, or its theft. I have not heard of any successful case
                against
                a CLEO for signing the certification for a gun that was
                criminally misused.  That is, in my opinion, a spurious
                excuse
                for not signing.  There is even a case addressing this
                issue,
                Searcy v. City of Dayton, 38 F.3d 282 (6th Cir. 1994). The
                estate
                of a drug dealer murdered by an off duty Dayton, Ohio, police
                officer with his personally owned "Mac-11" machine gun
                sued the
                city that employed the cop.  One of the grounds for suit
                was the
                police chief's having signed the transfer paperwork for the
                murder weapon.   The court held that that claim should
                have been
                dismissed by the trial court; without a showing that somehow the
                act of signing was negligent, (under Ohio law) and led to the
                harm (murder) complained of, there was no cause of action. 
                Signing the form  was not negligent in itself, nor was it a
                reckless or wanton act, as the  trial court claimed the
                plaintiff
                could try to prove at trial.  Although this case is only
                directly
                binding on the area of the 6th circuit, and need not bind state
                courts, the court recognized what common sense, and the 
                certification say, the person signing does not open himself up
                to
                any liability by doing so.
                
                     The case is something to which you can
                point a CLEO who
                claims to refuse to do the signoff because of liability.
                Incidentally Stephen Halbrook, a leading lawyer in gun rights
                cases, and a longtime lawyer for the NRA, as well as an author,
                says in a note in Machine Gun News (3/95) this case is the only
                instance of a registered machine gun being criminally misused by
                its registered owner he is aware of.  And it was by a
                police
                officer.  
                
                     The key to getting the LE certification
                is persistence.  
                
                                 
                NFA WEAPONS AND THE 4TH AMENDMENT  
                
                     As to surrendering your 4th amendment
                (search and seizure)
                rights, this is definitely true when one gets a Federal Firearms
                License.  The law allows the ATF to inspect your records
                and
                inventory once every 12 months without any cause, and at any
                point during the course of a bona fide criminal investigation
                (18
                USC sec. 923(g)).  They may inspect without warning during
                business hours. The only modification of the above pertains to
                the C&R FFL (type 03) where ATF must schedule the
                inspection,
                (C&R FFL holders do not have business hours) and they must
                have
                the inspection at their office nearest the C&R FFL holders
                premises, if the holder so requests.  ATF may look around
                the
                licensed premises for other weapons not on your records. 
                This
                means they take the position that if your licensed premises are
                your home they may search it, as part of the annual compliance
                inspection.  The constitutionality of the warrantless
                "administrative search" of licensees provided for in
                the Gun
                Control Act has been upheld by the US Supreme Court, see U.S. v.
                Biswell, 406 U.S. 311 (1972).  Biswell was partially
                overturned
                by Congress by 1986 changes to the requirements for a warrant
                under the GCA, but the administrative search provisions remain.
                
                     In addition, if one is also a SOT, ATF
                claims to have  the
                right to enter onto your business premises, during business
                hours, to verify compliance with the NFA.  Their regulation
                to 
                that effect is found at 27 CFR sec. 179.22.   The
                regulation is
                apparently based upon 26 USC sec. 7606:
                
                          7606.
                Entry of premises for examination of taxable
                     objects.
                     (a) Entry during day.
                           
                The Secretary may enter, in the daytime, any building
                     or place where any articles or objects
                subject to tax are
                     made, produced, or kept, so far as it
                may be necessary for
                     the purpose of  examining said
                articles or objects.       
                     (b) Entry at night.
                         When such
                premises are open at night, the Secretary may
                     enter them while so open, in the
                performance of his official
                    
                duties.       
                     (c) Penalties 
                     For penalty for refusal to permit entry
                or examination, see
                     section 7342.
                
                As 26 USC sec. 7342 provides for the penalty for a refusal to
                permit entry under section 7606 it is worth a look:
                
                     7342. Penalty for refusal to permit
                entry or examination.
                        Any owner of any
                building or place, or person having the
                     agency or superintendence of the same,
                who refuses to admit
                     any officer or employee of the Treasury
                Department acting
                     under the authority of section 7606
                (relating to entry of
                     premises for examination of taxable
                articles) or refuses to
                     permit him to examine such article or
                articles, shall, for
                     every such refusal, forfeit $500. 
                
                    They claims this right extends to examining
                your business
                records,  and firearms.   This would only apply
                to your NFA
                firearms, although  they could presumably examine other
                guns to
                make sure they were not  NFA firearms, and subject to the
                law.  
                This is not subject to the  controls found in the GCA,
                noted
                above, as the legal basis for the  search is not found
                there.  
                So they could claim a right to do this  sort of search once
                a
                month, or once a week.   I am not aware of any current
                abuse of
                the authority under this section.   While the
                regulation made by
                ATF only applies this authority to SOT's, the statute itself is 
                not so limited.   At least one court case has
                suggested this
                power  is available to search an FFL holder who is not an
                SOT. 
                (U.S. v. Palmer, 435 F.2d 653 (1st Cir. 1970)).
                 
                     As to one who is neither a FFL nor SOT,
                but only owns
                weapons  regulated under the National Firearms Act, the law
                seems
                clear, but  practice is a little murky.  ATF may only
                compel you
                to show an agent  upon request the registration paperwork,
                that
                is the Form 1, 2, 3, 4, 5  or whatever else might have been
                used
                to register the weapon.  See  26 USC sec.
                5841(e).   They do not
                have any right to compel you to show them the
                weapon.   However
                they apparently (I have no first hand knowledge) take the
                position that they can compel one to show ATF the weapon upon
                request, even if the owner has no FFL.  As always the
                Fourth
                amendment applies, and ATF may not enter your home or other
                place
                of storage of the NFA weapon, nor seize the weapon, without a
                warrant, or without falling under an exception the Supreme Court
                has created to the operation of the Fourth amendment.  They
                should also need a warrant to compel a non-FFL holder to show
                them the weapon, and I would insist upon that, myself. 
                
                           
                AMNESTIES FOR UNREGISTERED NFA WEAPONS  
                
                     As part of the new and revised 1968
                National Firearms Act, 
                there was one amnesty where folks could register any NFA
                weapons. 
                It went from 11/02/68 to 12/01/68, although the paperwork
                backlog
                went on for a while after.  According to 1995 ATF
                statistics (the
                number of firearms ATF reports as having been registered during
                the Amnesty goes up every year, as ATF recompiles the numbers)
                57,216
                weapons were registered on Form 4467 ("Registration of
                Certain
                Firearms during November of 1968"), which was the amnesty
                registration form.   This would have included weapons
                newly
                subject to registration, when they had not been before, like
                DEWAT's and destructive devices, as well as contraband firearms
                that should have been registered before and were not. 
                There was
                also a registration period after the enacting of the first 
                NFA, from July 26, 1934 up to September 24, 1934.  Anyone
                in
                possession  of an NFA weapon as of the July 26 date was
                supposed
                to register it, even  if they no longer had it, on Form 1
                (Firearms) in duplicate, with the  local IRS office. 
                No tax
                was due.  Not really an amnesty though, as the weapons were
                
                legal to have before the law was passed, at least under federal 
                law.  Some states had prohibited or regulated some NFA
                weapons 
                before 1934. In fact the Uniform Machinegun Act, which provided
                for registration of machine guns, adopted in a few states
                (Conn., 
                Va., Md., Ark., and Montana and possibly others) was developed
                with
                the support of the NRA, partly in an attempt to forestall the
                sort of
                regulation the feds ultimately adopted in 1934.  Before the
                changes to the NFA in 1968, a Form 1 was for a flat out
                registration of an existing gun, no tax.  A Form 1A was for
                a tax
                paid making, in the way we understand a Form 1 now.  
                
                     Before the NFA was changed in 1968, as
                part of the Gun
                Control Act of 1968, one could register unregistered existing
                weapons, however it meant you were admitting to possessing an
                unregistered weapon.  In fact the law required it, which
                was a
                reason the US Supreme Court used in gutting the registration
                scheme of the pre-68 NFA in Haynes v. US, 390 U.S. 85 (1968). 
                (It violated the 5th amendment right against compelling
                self-incrimination.)  However if there was no criminal
                intent to
                the possession (which tended to be demonstrated by attempting to
                register the weapon) then the Alcohol and Tobacco Tax
                Division of the Treasury Dept. would accept the application to
                transfer the weapon, or to register it.  ATT generally sent
                an 
                investigator to check out what was going on, and if deemed 
                appropriate, to help the applicant fill out the Form 1. 
                The Alcohol, 
                Tobacco and Firearms Division of the IRS (created out  of
                the '68 GCA, it
                became the Bureau of Alcohol, Tobacco and Firearms on July 1,
                1972) continued this practice until 1971, with  the
                transferor
                instead of the transferee admitting to possessing an
                unregistered
                weapon, when applying to transfer it.  
                
                      The US Supreme Court, in the case
                U.S. v. Freed, 401 U.S.
                601 (1971), decided existing weapons were unregisterable. 
                The
                provisions for requiring registration of existing (illegally
                possessed) weapons were removed from the NFA in 1968, among
                other
                changes.  The Secretary of the Treasury is authorized to
                conduct
                additional amnesties (Sec. 207(e) of P.L. 90-618, the 1968 Gun
                Control Act), at his discretion, provided each is not longer
                than
                90 days, and are announced in the Federal Register.  There
                has
                never been one.  ATF officials have stated there will never
                be another
                Amnesty, because it could ruin all prosecutions in progress at
                the time, as well as increase the number of NFA guns overnight,
                because people will make guns that don't exist now, to register
                them. 
                
                     In early 1994, ATF decided (in ATF
                Rulings 94-1 and 94-2)
                that three 12 gauge shotgun models, the USAS 12, Striker 12, and
                Street Sweeper, were destructive devices, owing to their
                non-sporting character, and having a bore over 1/2 inch, as all
                12 gauge shotguns do.  ATF required owners of these guns to
                register them, as NFA weapons.  This is not exactly an
                amnesty,
                as the weapons were not NFA weapons when made.  While ATF
                has not
                required the payment of the $200 making/transfer tax to register
                them, they had required the registrant obtain the law
                enforcement
                certification on the registration paperwork (Form 1). 
                According
                to the 7/95 Machine Gun News, NFA Branch has now dropped the
                requirement for the law enforcement certification on the initial
                Form 1 registration,  subsequent transfers will be by
                regular NFA
                procedures.  ATF began notifying owners of the guns on
                2/1/94 of
                the classification decision, and gave them 30 days to register
                the weapon or dispose of it, after notice.  Supposedly ATF
                calculated the 30 days from when the last owner (they could
                locate) of a weapon was notified.  If you purchased the
                weapon
                privately, and there was no "forward trace" paper
                trail, then you
                may not have known when the 30 days began to run.  However
                according to Machine Gun News, as of 7/95 ATF is still accepting
                registration applications.  It would be wise to contact
                them
                before assuming they will not let you register such a gun, and
                either throwing it away, or just keeping it without complying
                with the registration procedures.  
                
                     As this does constitute the
                addition  of existing
                unregistered weapons to the Registry, in my opinion the 
                Secretary should have used the amnesty procedures in the 1968
                GCA.   He did not because he did not want folks to be
                able to
                register any  unregistered NFA weapon, there is not a
                procedure
                for limiting the scope of an amnesty (although I suppose the
                Secretary of the Treasury could have made one up, and let people
                sue him).  However the fact that ATF chose not to either
                grandfather these shotguns, like they did with the open bolt MAC
                style semi-autos, or pre 11/81 AR-15 drop in auto sears, or have
                an amnesty, and require they be registered, in my opinion will
                cloud any attempts to prosecute persons possessing these weapons
                without having registered them.  
                
                     In all likelihood 18 USC sec. 922(o),
                the ban on civilian
                possession of machine guns registered after the law took effect,
                or never registered, precludes an Amnesty (as provided for under
                existing law) for machine guns.  You
                could register it, and comply with the NFA, but you would still
                be in violation of sec. 922(o), because the gun would have been
                registered after the law took effect.  The penalties are
                the same
                under either law.  One could register all other categories
                of NFA
                guns at an Amnesty. 
                
                            
                MACHINE GUN SEARS AND CONVERSION PARTS
                
                     The definition of
                "machinegun" in the NFA (26 USC sec.
                5845(b) includes parts to convert a gun into a machine
                gun.  Note
                that conversion parts are not included in the definition of
                "firearm" under the Gun Control Act, one of the few
                things I know
                of that is a firearm under the NFA, but not the GCA.  Thus
                the
                purchaser of a conversion part from an FFL need not do a 4473
                form, unlike  other NFA weapons.  Of course the host
                gun, if
                purchased from an FFL, will require the 4473.  This reading
                of
                the law is based on  numerous statements from ATF, and the
                definition of "firearm" under the GCA, which requires
                it be able
                to expel a shot.   However, at  least one very
                slow judge has
                decided that somehow the definition  of "firearm"
                in the GCA
                "incorporates" the definition of "machine
                gun" under the GCA
                (even though the law doesn't say that) and that a machine gun
                conversion part is a "firearm" under the GCA as well
                as the NFA.  
                I think the judge is clearly wrong, even ATF reads the law
                better
                than that, but the point is to be careful.  The case
                is  U.S. v.
                Hunter, 843 F.Supp 235 (E.D. Mich. 1994), and see also the same
                judge's second opinion in the same case, at 863 F.Supp. 462 (E.D.
                Mich. 1994).  These parts are called registered sears, as
                well as
                other parts or sets of parts to convert a gun into a machine
                gun. 
                
                     In every case, the part(s) are
                installed into a
                semi-automatic gun, and without any alteration to the semi-auto
                gun's receiver, the new part(s) will allow the gun to fire as a
                machine gun.  As a general rule a sear conversion is less
                desirable than an original gun, or a registered receiver
                conversion.  This is because if the registered part breaks
                or
                wears out it cannot be replaced, only repaired, if possible. 
                BATF considers replacing it with a new part to be the new
                manufacture of a machine gun, and a civilian could not own it,
                as
                it would have been made after the 1986 ban.  This
                wear/breakage
                thing is also true of the receiver on a gun where that  is
                the
                registered part, but in general the receiver is less subject to
                wear or breakage than a small part, like a sear.  
                Being larger,
                a  receiver may also be easier to repair.  The sear
                conversion
                will most likely not be just like the factory machine gun
                version; it will be working in  the semi-auto version of
                the gun. 
                A registered receiver conversion can  (and should, but
                isn't
                always) be mechanically identical to the original  full
                auto
                version of the gun, and factory spare parts may be used. 
                Some 
                sear conversions require altered parts, in addition to the
                registered sear.  
                
                     However for HK guns it is pretty much
                all there is,
                especially if you want an MP-5 type gun.  And if you want a
                version of the Colt 9mm AR machine gun, the auto sear route is
                more plentiful than the few registered receiver conversions, and
                the even fewer factory Colt guns, as the model was introduced
                (1985) right around the same time as the 1986 ban.  And in
                general the sear or other registered part is cheaper to buy than
                the same gun as a registered receiver, both because you aren't
                getting a gun also, and because it is less desirable. 
                However
                you may find that due to the escalating value of the semi-auto
                host guns, the conversion part already installed in a host gun
                may cost as much as a registered receiver conversion of the same
                gun, like an IMI semi-auto UZI with a registered bolt installed
                versus a registered receiver UZI conversion.   It pays
                to shop
                around.
                
                     A sear that does require alteration to
                the host gun's
                receiver is not a conversion part, and is not able to be
                registered as such.  Some slipped by NFA Branch, in
                particular
                AK-47 "sears" that required a hole be drilled in the
                gun's
                receiver, like a regular receiver conversion of the semi-auto
                AK. 
                Such "sears" in the hands of innocent buyers were left
                on the
                Registry, with the requirement that they were not to be removed
                from the host gun, in effect converting them into receiver
                conversions in the eyes of BATF.  However any in the
                possession
                of the persons who made and registered them were disallowed, and
                removed from the Registry. See Vollmer v. Higgins, 23 F.3d 448
                (D.C.Cir. 1994) for info on the AK sears.   Also see
                FFL Newsletter, Summer Issue 1988, Bureau of Alcohol,
                Tobacco and Firearms, page 2, Washington, D.C.
                
                     Some examples of conversion parts; a
                SWD Auto Connector (for
                AR rifles), an AR-15 drop-in auto sear, an HK sear, as made by
                Fleming Firearms, J.A. Ciener, and S&H Arms, among others, a
                AUG
                sear as made by F.J. Vollmer and Qualified Manufacturing, an
                FN-FNC sear, as made by S&H, an M-2 conversion kit for the
                M-1
                carbine, registered by many class 2's, a slotted UZI machine gun
                bolt, made by Group Industries, and many others, or a Ruger
                10/22
                trigger pack, as made by John Norell.  There are also sears
                to
                convert Glock and Beretta 92 pistols into machine guns, but I
                believe all of them are post-86 manufacture, and thus
                unavailable
                to civilians.
                
                     As the sears do turn the host gun into
                a machine gun, the
                host  gun is no longer regulated as a semi-auto, and is not
                subject to 18  USC sec. 922(v), (assault weapon law) or
                sec.
                922(r) (ban on domestic assembly from imported parts of an
                unsporting semi-auto rifle or shotgun), for example.  
                Thus you
                may put an  HK sear in a post 1989 import ban SAR-8 rifle,
                for
                instance, and then put  a regular pistol grip stock set on
                that
                otherwise thumbhole gun, as  well as a regular slotted
                flash
                hider.   The host gun need not even  have been on
                the planet when
                the sear was made.  This is how F.J. Vollmer  keeps on
                cranking
                out MP-5's even though the new making of MG's for 
                civilians was
                ended in 1986.  As long as the sear is in there you
                may  also
                have the barrel cut down to below 16 inches; a machine gun is 
                not also a short barreled rifle.   HOWEVER, if the
                sear is placed
                into a second gun, the first gun is no longer a machine gun, and
                must comply with the laws regulating it as a
                semi-auto.   In my
                example, the barrel must grow back, and the thumbhole stock
                needs
                to return.  If the sear in question is a AR-15 drop-in auto
                sear,
                the gun needs to have the M-16 internal parts needed for the
                sear
                removed as well, lest it be induced to fire more than one shot
                at
                a time, as was done in the U.S. v. Staples case.
                
                     The ability to move the sear or other
                parts between like
                guns is a nice feature of the sear; you can have all your HK
                guns
                be full autos, one at a time, and only have one registered item,
                and one transfer tax to pay, for example.   However
                each sear or
                conversion kit may require a bit of fine tuning to the host gun
                to make it work, this swapping feature may be overrated,
                depending on the design of the sear and of the host gun.
                
                     NFA Branch desires that folks who
                install sears into guns
                where the sear is not very accessible, HK guns in particular,
                tell them the make, model and serial number of the gun into
                which
                the sear is installed.   This makes it easier on them,
                as they do
                not have to open the gun up to see the sear, if they know that
                gun is the one with the sear in it.   This is called
                "marrying"
                the sear to the gun.   It is especially useful when
                the host
                semi-auto has been modified so as to make it potentially illegal
                without the sear, like putting a shoulder stock on an H&K
                SP-89
                pistol, or cutting the barrel of an HK-94 to less than 16
                inches. 
                You may "divorce" the two, but don't if the host gun
                will end up
                an unregistered short barreled rifle, or other unregistered NFA
                weapon.   Often this marriage info is in box 4(h) on
                the Form 4,
                so anyone who looks at the paperwork can see the sear is in that
                gun; local law enforcement, for instance.
                
                     If the gun is a sear conversion you may
                not alter the
                receiver to full auto configuration, in particular you may not
                install a push pin lower on your HK.  You may alter  a
                push pin
                lower shell to accommodate your clip-on trigger pack, so it
                looks
                authentic, but don't alter the receiver.   You may
                also alter one
                of the MG burst packs to fit on your semi-auto receiver,
                provided
                it is also modified internally so it no longer just uses the MG
                trigger pack with the original MG trip.   Making an
                unaltered MG
                trigger pack fit the semi-auto is making a new conversion
                device;
                some registered HK conversion parts are MG trigger packs
                modified
                to fit right on the semi-auto receiver.
                
                     This is an area with a variety of items
                registered; many in
                the frenzy of registration after the 1986 making ban was being
                passed into law, similar to the frenzy of making seen in 1994
                during Congressional deliberation on the ban on new manufacture
                of "semi-automatic assault weapons" for sale to
                civilians.
                
                     A few notes: before November, 1981,
                BATF did not consider
                the drop-in AR-15 sear to be a machine gun in itself, because
                you
                had to replace all the internal parts with M-16 parts, as well
                as
                install the sear, and thus it didn't convert the AR by itself. 
                However in ATF Ruling 81-4, BATF changed its mind about what a
                thing had to do in order to be a conversion part, grandfathered
                all AR sears made before the ruling, and decided all made after
                that needed to be registered.  HOWEVER, the fact that the
                sear
                itself, if made before 11/81, and sold through ads in Shotgun
                News to this day (they sure made a lot of 'em back then, or
                maybe
                not) is not required to be registered, DOES NOT mean you may
                install it in an AR-15, or even possess it with an AR-15 rifle. 
                Either scenario is a machine gun also, and also needs to be
                registered.  Except of course you cannot register it
                anymore, and
                thus it is just a millstone, waiting to send you to a federal
                prosecution.  And that exact scenario has been the basis
                for many
                prosecutions.   
                
                     Likewise an M-1 carbine receiver and an
                M-2 carbine receiver
                are identical, and all the parts to convert a gun from an M-1 to
                an M-2 are available on the surplus market.  HOWEVER having
                all
                the parts, and an M-1, or even just some of the M-2 parts
                together, is a machine gun under the NFA.   While the
                US Supreme
                court decision in the Staples case should help to protect truly
                innocent possessors of such things, you are playing with fire.
                
                     A registered sear is not a license to
                use it to convert any
                gun you wish.  BATF takes the position that installing a HK
                sear
                in any gun but an HK, or a HK clone gun (like one of the Greek
                or
                Portuguese G-3 semi-autos) is not allowed, and is making an
                unregistered machine gun.  So while you can put it in any
                HK type
                gun, don't put it in something else, like an FNC or AK (it has
                been done) thinking the sear is a license to convert any gun you
                can shoehorn it into.  Or if you want to do that, take BATF
                to
                court first, don't just do it.
                
                                              
                DEWATs  
                
                     A DEWAT is an unserviceable gun that
                has an intact receiver,
                thus, as of the GCA of 1968, it is a machine gun.  In 1955
                the
                ATT decided that a gun that was a registered war souvenir (or
                for
                a time, a contraband unregistered gun) could be removed from the
                coverage of the NFA if it was rendered unserviceable by steel
                welding the breech closed, and steel welding the barrel to the
                frame.  All this was to be done under the supervision of an
                ATT 
                inspector.  See Revenue Ruling 55-590.  The gun became
                a wall 
                hanger, ornament, like parts sets now.  This was not the
                same as
                an unserviceable gun, which was still subject to the NFA, but
                exempt from the transfer tax.  These steel welded guns were
                DEWAT's.  DEWAT stands for DEactivated WAr Trophy; it was
                regularly done for servicemen who wished to bring home NFA war
                souvenirs.  It was also done to WWI and WWII era guns
                imported as
                surplus by companies like ARMEX International, and Interarmco,
                and then sold through the mail in ads in gun magazines. 
                The
                glory days before 1968.  A DEWAT must now be registered to
                be
                legal, there is no longer a legal difference between a DEWAT and
                an unserviceable weapon.  A few states only allow
                individuals to
                own DEWAT machine guns, Iowa comes to mind.
                
                    A DEWAT machine gun transfers tax free, as a
                "curio or
                ornament", on a Form 5.  To be a DEWAT, a gun should
                have a steel
                weld in the chamber, and have the plugged barrel steel welded to
                the frame or receiver.  Having said that, a gun may be
                registered
                as unserviceable and not be de-activated in this manner. 
                It may
                have cement or lead in the barrel, or a piece of rod welded,
                soldered or brazed in the barrel. Despite the repeated warnings
                from ATT, apparently DEWATs were made or imported that did not
                have steel welds.  And a weapon registered as
                "unserviceable"
                before 1968 was not held to these standards.  One
                (ostensible)
                reason machine gun receivers were redefined as machine guns in
                1968, thus bringing DEWATs under the NFA regulation, was that
                folks were regularly and easily making their DEWATs live guns
                w/o
                complying with the law. Some barrel plugs were so poor they
                would
                fall out with little coaxing.  The thing with buying a
                DEWAT is
                that it may be easy to make it live, or it may be hard. 
                The gun
                may be pristine or rather beat up.  They usually cost less
                than a
                live gun because they will not be 100% original if made live. 
                However if you just want a shooter buying a DEWAT and getting it
                made live can often be cheaper than an original gun.  DEWAT
                guns
                are best not bought sight unseen, unless you do not wish to make
                it live, but have it as a wall hanger. The exact state and
                extent
                of the welds will determine how hard it is to make live. 
                However
                if you want a wall hanger, a dummy gun is much cheaper, and
                requires no paperwork.  They can look totally
                authentic.  They do
                not have an intact machine gun receiver, but a partially
                machined
                dummy receiver.
                    
                     To re-activate the gun, ATF requires
                you file a fully
                completed Form 1 (ie you get the gun on a Form 5, including the
                law enforcement certification, photo and fingerprints.  You
                have
                to do all that again for the Form 1), and pay the $200 tax the
                gun was exempt from before. Then when that is returned approved
                you can break the welds off the receiver, and install a
                replacement barrel, or get the weld out of the barrel, if a
                spare
                cannot be found.   In the alternative, a Class 2
                manufacturer may
                re-activate the gun, and file a Form 2 reflecting the gun is now
                live.  ATF considers re-activating to be manufacturing, and
                requires the re-activator to mark the gun with his name and
                address, whether done on a Form 1 or Form 2.  If you sent
                your
                DEWAT to a Class 2 to make live he would have to transfer it
                back
                to you on a fully completed Form 4, as a tax paid transfer. 
                These procedures are not in the NFA law nor the regulations. 
                They are apparently based in part on the Revenue Rulings that
                created the DEWAT program in the 1950's.  As a DEWAT was
                not a
                NFA firearm, before 1968, requiring the making tax made sense
                then as you were making a machine gun out of something that was
                the equivalent of a door stop, legally.  Now that is not
                true,
                the DEWAT is a machine gun, and no making tax should attach, as
                you are not "making" anything, merely changing the gun
                from
                unserviceable to serviceable. 
                    
                     Folks who are around NFA guns for very
                long will find there
                are still a lot of DEWAT guns that were never registered during
                the Amnesty, and are  now contraband unregistered machine
                guns.  
                Folks have them in closets, up over the mantle... They can be
                stripped of parts, to make a parts set, and have the receiver
                thrown away.   Torch cutting the receiver into 4 or
                more parts
                may be acceptable; you would have to contact ATF to find out the
                current standard for "de-mill"ing (short for
                demilitarize) a
                receiver; a de-milled receiver is not a firearm, it is scrap
                metal.   A receiver only cut in half may well not be
                scrap; ATF
                has prosecuted folks where they could duct-tape together the
                receiver and get the gun to fire.   Best to check on
                this before
                proceeding.  The U.S. v. Staples, - U.S. - (1994), decision
                should end such ridiculous prosecutions, now the feds must
                prove,
                beyond a reasonable doubt, you knew the gun was subject to the
                NFA, ie you knew it was a machine gun, that it could fire more
                than one shot with a pull of the trigger, and so on.  But
                even if
                there were no prosecution, you could lose the receiver and or
                parts to a forfeiture, if ATF though it was in fact a machine
                gun, and it was not registered.   
                
                                       
                ANY OTHER WEAPONS  
                
                     An AOW is:
                     "...any weapon or device capable
                of being concealed  on the
                     person from which a shot can be
                discharged through the
                     energy of an explosive, a pistol or
                revolver having a smooth
                     bore designed or redesigned to fire a
                fixed shotgun shell,
                     weapons with combination shotgun and
                rifle barrels 12" or
                     more, less than 18" in length,
                from which only a single
                     discharge can be made  from either
                barrel without manual
                     reloading, and shall include any weapon
                which may be readily
                     restored to fire.   Such term
                shall not include a pistol or
                     revolver having a rifled bore, or
                rifled bores, or weapons
                     designed, made or intended to be fired
                from the shoulder and
                     not capable of firing fixed
                ammunition." 26 USC sec.
                     5845(e). 
                
                     Thus the question to be answered in
                deciding if a weapon is
                an AOW would be, does it fit into any of the three categories
                below: 
                     1) Is the weapon both not a pistol or
                revolver, and capable
                of being concealed on the person?
                     2) Or is it a smooth bore pistol or
                revolver?  Examples of
                this include the H&R Handy-Gun, or Ithaca Auto-Burglar
                gun.  This
                does not include weapons made from a shotgun.  That would
                be a
                short barreled shotgun.  The receiver of a smooth bore
                pistol, in
                order to be an AOW, must not have had a shoulder stock attached
                to it, ever.  The shoulder stock attachment deal on some
                H&R
                Handy Guns, with a stock, will make them into a short barreled
                shotgun. 
                     3) Or is it a combination gun, a
                shoulder fired gun with
                both rifled and smooth barrels between 12" and 18"
                long, and
                which has to be manually reloaded?  Examples of this
                include the
                M-6 military survival gun, with a single shot barrel in .22
                Hornet, and a  companion .410 shotgun barrel, as well as
                some
                models of the Marble's Game Getter.   
                
                     Weapons that fit the first category
                above are commonly
                called gadget guns;  pen guns, stapler guns, cane guns,
                alarm
                clock guns, flashlight guns, the list of objects is pretty
                long.  
                A few have been removed from the scope of the law because their
                collector status makes them unlikely to be misused; original
                Nazi
                belt buckle guns for example.   See the C&R list
                for these.  
                
                     If a gun has rifled barrel(s) of less
                than 16", and it has
                never had a shoulder stock it would be a pistol, unless it
                either
                has no grip at an angle to the bore, or if it has more than one
                grip.  ATF has made the questionable decision that a
                handgun with
                more than one grip is an AOW.  This is based on the gun a)
                being
                concealable on the person, and b) not meeting the definition of
                a
                "pistol" in the regulations promulgated under the NFA,
                since they
                say a pistol has a single grip at an angle to the bore. 
                However,
                at least one federal court has decided that if the grip is added
                later, the gun is not "originally designed" to be
                fired by
                holding in more than one grip, and thus putting a second grip on
                a pistol does not make it an AOW.   Whether ATF will
                regard the
                decision as binding beyond that case is unknown, I would doubt
                it. The case is U.S. v. Davis, Crim No. 8:93-106 (S.C. 1993) 
                (Report of Magistrate, June 21, 1993).   By the same
                token in mid
                1996, ATF decided that "wallet" holsters for small
                guns, from
                which the gun could be fired, somehow are AOW's.  This
                would
                affect, for example, the North American Arms mini-revolver and
                the wallet holster NAA sold for the gun, as an accessory. 
                ATF
                seems to be thinking that the grip has disappeared, and thus it
                fits into the first category.  This strikes me as bizarre
                and
                stupid, and I suspect the courts will have their shot at it,
                given how common the wallet holsters are.  What if you put
                the
                gun in a purse, from which it can be fired?  A folded up
                newspaper?   
                
                          27 CFR
                sec. 179.11 - "pistol.  A weapon originally
                          designed,
                made and intended to fire a projectile
                          (bullet)

                          fixed
                shotgun ammunition." 
                
                There is also a revolver definition, but it does not add
                anything
                except a provision for guns with revolving cylinders, rather
                than
                permanent chambers.  
                
                     Note that this definition is only in
                the rules for the NFA,
                and not the GCA.   It is designed to interact with the
                AOW
                definition.   For example even though this definition
                excludes
                such things as the .410 T/C Contender pistol from the pistol
                definition, it is also not an AOW as it has a rifled bore. 
                And
                it is also a handgun under the GCA.  The NFA statute does
                not
                define "pistol" or "revolver".  I think
                that excluding handguns
                designed to be fired when held in two hands is not necessarily
                justifiable. But it allowed them to declare that an HK SP-89
                pistol with a K grip is an AOW.   As is an M-11/9 or
                TEC-9 with a
                foregrip. The Auto Ordnance 1927-A3 pistol is apparently
                exempted, for historical authenticity.

                and from which a
                     destructive device may be readily
                assembled.   The term
                     'destructive device' shall not include
                any device which is
                     neither designed nor redesigned for use
                as a weapon; any
                     device although originally designed for
                use as a weapon,
                     which is redesigned for use as a

                     line throwing, safety or similar
                device; surplus ordnance

                other device which the
                     Secretary of the Treasury or his
                delegate finds is not
                     likely to be used as a weapon, or is an
                antique or is a
                     rifle which the owner intends to use
                solely for sporting
                     purposes."  
                
                     Secretary in the above refers to the
                Secretary of the
                Treasury, unless it says otherwise.  The fee for the FFL to
                deal
                in DD's is $1000 a year (type 09), and one must also be a
                special
                taxpayer, add another $500 a year.  Making them requires a
                different $1000 a year FFL (type 10), although an individual may
                make them on a Form 1, tax paid ($200).  Transfers require
                the
                whole routine just like full-autos; a form 4, $200 tax, a law
                enforcement sign-off, pictures and fingerprints.  Most
                class 3
                dealers don't have the $1000 a year FFL to deal in
                DD's.   Note
                that antiques are excluded.  Thus the definition of an
                antique
                NFA firearm is important.

                available in the
                     ordinary channels of commercial
                trade."  
                
                     Some examples of what is a DD and what
                is not: 
                 
                     Muzzle loading cannon - NOT, as it is
                an antique design,
                unless it has some special features allowing breech
                loading.  
                     Explosive grenade - is a DD
                     Molotov cocktail - is a DD  
                     M-79 or M-203 40mm grenade launcher -
                is a DD  
                     Smooth bore 37mm projectile launcher -
                not a DD.   Not even
                a title 1 firearm.   This item falls under the
                "not a weapon"
                (signaling device) exception, I believe. Generally a large bore
                device for which no anti-personnel ammo has ever been made will
                NOT be a DD.  This used  to be true of the 37mm
                guns.   However,
                according to ATF, some folks have started making anti-personnel
                rounds for these guns, and ATF has ruled that possession of a
                37mm launcher and a bean bag or rubber shot or similar
                round  is
                possession of a DD, and at that point the launcher needs to be
                registered.  Put another way, before you make or buy 
                anti-personnel rounds for your 37mm launcher, register it as a
                DD.  The rounds themselves, not being explosive, incendiary
                or
                poison gas, are  not regulated in themselves either. 
                It is just
                the two together.  See ATF Ruling 95-3.
                     40mm grenade for an M-79 or M-203 - a
                DD.  
                     Non-explosive 40mm practice ammo - not
                a DD.   Commercial
                making of it would require a type 10 FFL though, as although the
                ammo is not itself classified as a DD, making ammo for a DD
                requires the FFL. 
                     Non-sporting 12 gauge shotgun - is a
                DD, because it has a
                bore over 1/2", and is not exempted unless it meets the
                "sporting
                use" test. Check out the case Gilbert Equipment Co., Inc.,
                v.
                Higgins, 709 F. Supp. 1071 (D. Ala. 1989) for how the sporting
                use test has been  re-interpreted from what it meant when
                the law
                was enacted to having  ATF be arbiters of what is
                "sport".  
                     Flame Thrower - not a DD, nor even a
                firearm.  Unregulated
                as to possession, under federal law.  Great way to clear
                snow off
                the driveway. 
                     Japanese Knee Mortar - A DD.  Even
                though there is no
                available ammo for it, explosive or otherwise, and hasn't been
                since 1945, because anti-personnel ammo was made for it in the
                past, it is a weapon.  As it has a bore over 1/2" and
                isn't
                sporting, it is a DD. 
                
                                       
                SOUND SUPPRESSORS
                  
                     While the statute calls these devices
                "silencers" or
                "mufflers", the US NFA industry term is "sound
                suppressor", as
                the word silencer has been given a negative connotation, and
                because it is inaccurate, as these devices do not eliminate all
                sound from firing a gun.  However you can point the folks
                who get
                all high and mighty about the use of the word
                "silencer" to this
                definition; it is the  legal term.
                
                          18 USC
                sec. 921(a)(24)  "The term 'firearm silencer' or
                     'firearm muffler' means any device for
                silencing, muffling,
                     or diminishing the report of a portable
                firearm, including
                     any combination of parts, designed or
                redesigned, and
                     intended for use in assembling or
                fabricating a firearm
                     silencer or firearm muffler, and any
                part intended only for
                     use in such assembly or
                fabrication."
                  
                     As can be seen this covers improvised
                sound suppressors, and
                component parts of a sound suppressor.  There is no thresh
                hold
                level of sound reduction for something to fall under this
                definition.  ATF used to require the device
                "appreciably" lower
                the sound (see Revenue Ruling 57-38); now the working definition
                seems  to be anything that traps gas from the muzzle of the
                gun,
                or from  porting of the barrel, is a sound
                suppressor.  In
                general recoil  compensators and flash hiders do not fall
                under
                this definition, but some designs could fall into the
                category.  
                As with any borderline  device the thing to do is to get a
                written opinion from the Technology  Branch of ATF.  
                It is what
                they exist to do.  
                
                     Note that the silencer definition
                applies only to devices
                for firearms, i.e. powered by an "explosive".  An
                air gun
                silencer is not covered.  But if it can be used on a
                firearm it
                would be.  Thus an airgun silencer permanently attached to
                the
                airgun, or too flimsy to be used on a firearm, should be exempt.
                
                If you have an interest in pursuing  this line of thought
                submit
                a sample or drawings to ATF Tech. Branch. I am not aware of any
                airgun silencer currently made, or determined to be exempt from
                this definition.   But clearly there is room under the
                definition
                for such a gadget.   Likewise, since antique guns, as
                defined in
                the GCA are not "firearms", a silencer for such a gun
                is not, or
                should not be, covered. Perhaps one fitted permanently to a
                pre-1899 gun?  The mind reels.     
                
                                      
                SHORT BARRELED RIFLES
                
                    A short barreled rifle (SBR) is defined in
                the law as:
                     26 USC sec. 5845(a)
                     *  *  *  *
                     (3) a rifle having a barrel or barrels
                less than 16 inches
                     in  length;
                     (4) a weapon made from a rifle if such
                weapon as modified
                     has an  overall length of less
                than 26 inches or a barrel or
                     barrels of less than 16 inches in
                length; * * *
                
                     The NFA law also  defines
                "rifle":
                
                     26 USC sec. 5845(c)  "The
                term 'rifle' means a weapon
                     designed or  redesigned, made or
                remade, and intended to be
                     fired from the shoulder  and
                designed or redesigned or made
                     or remade to use the energy of an 
                explosive in a fixed
                     cartridge to fire only a single
                projectile through  a rifled
                     bore for each pull of the trigger, and
                shall include any
                     such  weapon which may be readily
                restored to fire a fixed
                     cartridge. 
                
                    Thus you can see why a machine gun is not
                also a short
                barreled rifle; it is not a rifle.  And you can see why a
                barrel
                is not subject to regulation, or registration, in itself. It is
                a
                barrel, it cannot discharge a shot.  A receiver alone is
                also not
                a short rifle; a short rifle is  only a complete weapon
                that fits
                into the length parameters outlined. 
                
                    ATF takes the position that this includes any
                combination of
                parts from which a short barreled rifle can be assembled. 
                And
                they said this included a set of parts with dual uses. In the
                Supreme court case of Thompson/ Center Arms v. US, - U.S. -
                (1994)
                ATF said it was a set consisting of a receiver, a 16"+
                barrel, 
                a pistol grip stock, a shoulder stock, and a barrel less than 16
                inches long.  The idea of the kit was that
                you needed only one receiver, and you could have both a rifle
                and
                pistol in one gun.  While making a pistol out of a rifle is
                making
                a short rifle, ATF has long approved of converting a pistol into
                a rifle, and then converting it back into a pistol, that was not
                an issue.  T/C made one set on a Form 1, then sued for a
                tax refund, claiming the set was not a SBR, unless it actually
                was assembled with the shoulder stock, and short barrel,
                something they instructed the purchaser of the set not to
                do.  
                The Supreme court disagreed with ATF, and agreed with
                Thompson/Center.
                
                    The court said that a set of parts was not
                a  short barreled
                rifle, unless the only way to assemble the parts was into a
                short
                barreled rifle.  As this set had a legitimate, legal, use
                for all
                the parts it was OK.  However they also approved of lower
                court
                cases holding that the sale by one person, at the same place, of
                all the parts to assemble an AR-15, with a short barrel, was
                sale
                of a SBR, even if they weren't assembled together at the moment
                of the bust, and had in fact never been assembled.  See
                U.S. v.
                Drasen, 845 F.2d 731  (7th Cir. 1988).  This was
                because the only
                use for the parts was a SBR.   If the person in that
                case also
                had a registered M-16, then there would be a legitimate use for
                the SMG barrel, and there shouldn't be a problem.  
                And the Court
                agreed, of course, that a fully assembled rifle with a barrel
                less than 16", or an overall length of less than 26"
                was also
                subject to registration.  Although it was not addressed in
                the case,
                the rule is that an otherwise short barreled rifle that is very
                easily restored to firing condition (readily restorable); e.g.,
                one missing a firing pin, but for that pin one may substitute a
                nail or other common object, is also subject to the law.  
                
                    Therefore, if one has a semi-auto HK-91, and
                an HK-93
                converted with an auto sear, and having a barrel less than 16
                inches, one may not remove the sear from the HK-93 and put it on
                the HK-91.  That would leave the semi-auto pack from the
                HK-91,
                and the receiver/barrel combination from the HK-93; a set of
                parts for assembling a rifle, and said rifle would have a short
                barrel, and further not be  registered.   I think
                that if one
                disposed of all trigger packs one had, except the one the sear
                was in, one could legally swap it between the rifles, without
                having to register the HK-93 as a SBR.  The leftover HK-93
                receiver and barrel setup would not be capable of firing a shot,
                with the parts in the possession of the owner, except with the
                sear converted pack, and using that on it would be
                OK.   HOWEVER,
                I think ATF would disagree, and would prosecute should such an
                arrangement be attempted.  If someone is serious about
                doing
                this, they need to ask Technology Branch if they would agree
                with
                the reasoning outlined.  If they didn't, one would need to
                sue,
                or run the risk of having to fight it in a criminal, rather than
                civil, context.   
                
                                           
                APPENDIX
                                     
                STATE NFA RESTRICTIONS 
                
                    Here is my attempt to list what state allows
                what in terms of
                NFA weapons.  The "Y" indicates state law allows
                private
                individuals to own the weapon in question.   Most of
                the "Y"
                states require the weapons be possessed in compliance with
                federal law to be legal under state law.  Some of the
                "N" states
                may allow only police officers to possess them, or dealers, or
                neither. Basically if the privileged class was so narrow, by
                statute, I said "N".   In many states the
                class of folks able to
                own NFA weapons is narrow by practice (California), or because
                no
                law enforcement officers will sign the certification needed for
                a
                transfer to an individual.  Some of the "N"
                states may also have
                grandfathered weapons, the "N" applies to a 
                current transaction. 
                 Some "N" states may also allow unserviceable
                weapons.  Some
                states may regulate one or more of these weapons as handguns.

                A Note about NFA Weapons and California 
                
                As a general rule the definitions of NFA weapons, as regulated
                in
                California, track exactly the federal definitions, and
                categories.
                
                Cal. Penal Code Sec. 12020(a) prohibits the possession of, among
                other
                things, AOW's (Any other Weapons) and short shotguns and short
                rifles.
                Subsection (b) lists exemptions to the application of
                (a).    
                
                Subsection (b)(7) of section 12020 exempts any "firearm or
                ammunition" 
                lawfully possessed under federal law and on the C&R
                list.   
                Subsection (b)(8), exempts ALL AOW's except pen
                guns.   
                Subsection b(2) is the exemption for the movie permit for short
                shotguns 
                and short rifles with the procedure for its issuance found at
                section 12095.   
                
                Californians can legally possess any AOW, except a pen gun, as
                long
                as it is possessed in compliance with federal law. 
                Likewise they
                can possess any C&R listed short rifle or short shotgun. 
                
                Short shotguns and short rifles are defined at (c)(1)
                and (c)(2) respectively; the definitions are essentially the
                same as
                federal law.   HOWEVER, unlike the feds, California
                courts have
                ruled that the length of a rifle with a folding stock is
                measured with the stock folded, not extended, as the feds
                do.  So a 
                gun that is not a short rifle under federal law may be one under
                California 
                law.  See People v. Rooney, 17 Cal.App.4th 1207 (1 Dist.
                1993).
                 
                Any firearm whose possession is otherwise prohibited
                by subsection (a) is ok, under b(7), if the gun is a C&R one
                and lawfully possessed under federal law.   This would
                not provide an 
                exemption to the requirement for a state permit for a machine
                gun, 
                as 12020(a) does not regulate mg's.   That is section
                12220 (ban) 
                and 12230 et seq. (permits).  Rules for DD's are at section
                12301 et seq.  
                Silencers are regulated at section 12500 et seq.   The
                state Department
                of Justice has totally discretionary authority to issue permits
                to possess DD's or machine guns.   Civilians are
                totally prohibited 
                from owning silencers.
