Griffin Armament | CAM-LOK Universal Piston (AAC)

The Griffin Armament CAM-LOK universal piston is the piston component (bronze-colored part installed in the suppressor) of the CAM-LOK QD mounting system. It converts a suppressor to a faster, more secure attachment method for tilt-barrel (browning-style) pistols when paired with a CAM-LOK barrel adapter. The CAM-LOK piston accepts a 3/4″ socket for prevailing-torque installation and uses a tapered lock and three 120-degree mounting positions to reduce the risk of loosening and baffle or end-cap strikes common to legacy direct-thread pistons.

Typical applications include range training and competitive pistol shooting where rapid, repeatable attachment and alignment are important. The piston is part of a universal system that enables compatibility between supported suppressors and CAM-LOK barrel adapters without disassembling the suppressor.
