Griffin Armament Piston Barrel Adapter CAM-LOK 13.5x1 LH - PI1351LH

This is a barrel adapter designed for Griffin Armament's Universal QD piston systems, featuring the patented CAM-LOK (Covert Application Mount-Locking) attachment mechanism. The adapter uses a forward taper surface that locks with the piston to reduce or eliminate baffle and end cap strikes, and includes coarse top-cut threads for increased durability. Installation is straightforward with a 3/4-inch or 19mm wrench pattern for socket wrench application.
