Abstract

An M16 type rifle is disclosed having a gas piston assembly with a relatively large piston area and sufficient stroke to actuate the M16 bolt carrier assembly in order to allow the M16 rifle to be chambered for short low-pressure pistol cartridges such as the 45 ACP, 10 mm, and 40 S&W. The gas piston assembly provides relatively constant contact between the piston rod and the gas carrier key of the conventional M16 bolt carrier assembly.
