P308 Piston Bolt Carrier Assembly

Our 1-piece billet machined P308 piston bolt carrier assembly is custom manufactured with the mechanical key built in and positioned behind the cam pin. As a result, this prevents carrier tilt and eliminates the possibility of the key becoming misaligned. All gas piston carriers feature nickel plated bolts, extractors, and chrome firing pins. In addition, all piston carriers come standard with POF-USA's Roller Cam Pin.
