Griffin Armament CAM-LOK Universal Piston

The Griffin Armament CAM-LOK (Covert Application Mount-Locking) piston is the bronze-colored piston component designed for use with CAM-LOK barrel adapters. This piston converts a suppressor to a faster, more secure quick-detach mounting solution for browning-style (tilt-barrel) pistols compared with legacy single-piece direct-thread pistons. The CAM-LOK piston installs in the suppressor and interfaces with a CAM-LOK barrel adapter to provide repeatable, tool-assisted attachment and improved retention during cycling.

Key Specifications

• The interface is a CAM-LOK (Covert Application Mount-Locking) universal QD piston.
• Mounting offers three positions separated by 120 degrees for rapid, repeatable alignment.
• This listing is for the piston (bronze-color part installed in the suppressor).
• The piston material is 17-4 stainless steel.
• The component is H900 heat treated for improved durability and wear resistance.
• Compatibility is with SilencerCo 3-lug barrel adapters (barrel adapters sold separately).
• The design includes an internal taper lock surface intended to reduce baffle and end cap strikes.
• The total piston weight is identical to legacy direct-thread pistons.
• The system supports tool-installation with a 3/4 socket and prevailing torque to secure the mount.

As the piston half of Griffin Armament’s CAM-LOK system, this component brings tool-assisted repeatability and a taper-lock interface to suppressor mounting on compatible pistols. Its construction and heat treatment prioritize durability and alignment accuracy, and its interchangeable design enables use across CAM-LOK-compatible adapters without disassembly of the suppressor. For users who value reliable, secure quick-detach mounting on tilt-barrel pistols, this piston provides a practical upgrade path from legacy direct-thread systems.
