AR SERIES RIFLES CAUTIONARY INFORMATION
WARNING
There are certain safety procedures relative to the handling and firing of the AR series of rifles and ammunition which every individual must follow to avoid possible injury or death.
DANGEROUS PROCEDURES
Never interchange bolts and/or bolt carrier groups between two weapons without checking headspace before firing. Bolts may appear the same, however, interchanging them may result in incorrect headspace, which in turn may cause the weapon to blow up. When assembling the bolt carrier group, insure that the Bolt Cam Pin is installed. The weapon may fire without it, but it will blow up. Failure to remove water from the barrel may result in the weapon blowing up. If the weapon has been submerged in water, exposed to heavy rain and/or dew, or there is any reason to believe there is excess moisture in the barrel, point the muzzle of the weapon toward the ground and pull the charging handle 2 to 3 inches to the rear, breaking the seal formed by the chambered round and allowing the water to drain out of the barrel. Release the charging handle and strike the forward assist to make sure the round is reseated in the chamber and the bolt is locked. If a noticeable difference in sound or recoil is experienced, further firing should be suspended. Either of these conditions could indicate an incomplete propellant combustion and present the possibility that the projectile has not been propelled with sufficient force to clear the bore. In such instances, the bolt should be retracted slowly to remove and identify the fired cartridge case. The weapon should be cleared and examined for the presence of unburned propellant grains in the receiver, or possible presence of a bullet remaining in the bore. Any unburned propellant or obstruction in the bore should be removed before further firing.
