Griffin Armament Piston Adapter 13.5×1 LH

The Griffin Armament CAM-LOK piston barrel adapter provides a rapid, secure mounting interface for compatible Browning-style (tilt barrel) pistols. It replaces legacy single-piece direct-thread pistons with a patented universal QD piston attachment system designed for faster attachment and improved alignment. The adapter uses a stepped interface and forward taper to reduce the risk of baffle or end cap contact during mounting. Durable finishing and material choices are included for long-term use.
