Apparatus and methods for a bolt carrier assembly for direct gas operated firearms

Abstract

An apparatus and methods are provided for a bolt carrier that optimizes the operation of direct gas operated firearms. The bolt carrier is a cylindrical member that reciprocates longitudinally within an upper receiver of the firearm. A distal end of the bolt carrier supports a bolt while a proximal end moves within a receiver extension. The proximal end includes a boss, flutes, and a beveled ring. The boss and the beveled ring are configured to reduce the tilt of the bolt carrier when in a battery position. Different diameters of the boss and the beveled ring cause the bolt carrier to seat advantageously in various positions within the receiver extension. The flutes allow air transfer into and out of the space between the proximal end and the receiver extension to prevent air pressure from hindering the reciprocating motion of the bolt carrier.
