Griffin Armament | CAM-LOK Universal Piston | Dead Air

The Griffin Armament CAM-LOK® universal piston is the bronze-colored piston component installed in compatible suppressors to enable a rapid QD mounting system. It converts legacy direct-thread pistons to a three-position CAM-LOK interface that reduces the risk of loosening during slide cycling and improves repeatable alignment. Typical applications include range training and pistol competition where fast, secure attachment and repeatable point-of-impact are important.

Product Specifications

• The manufacturer is Griffin Armament.
• The UPC is 791154085028.
• The product is a universal QD piston (the bronze-colored piston installed in the suppressor body).
• The interface is the CAM-LOK® (Covert Application Mount-Locking) system.
• The piston offers three 120° mounting positions for rapid attachment.
• The internal taper surface provides a taper-lock engagement with CAM-LOK barrel adapters to reduce baffle and end cap strikes.
• This piston is compatible with 3-lug CAM-LOK barrel adapters (barrel adapters sold separately).
• The material is specified as 17-4 stainless steel.
• The piston receives H900 heat treatment for improved durability and wear resistance.
• The piston supports installation with a 3/4 socket wrench using prevailing torque.
• The design maintains a total system weight identical to legacy direct thread pistons.
• Manufacturing tolerances emphasize squareness and concentricity to minimize point-of-impact shift.
• This part is intended for use with browning-style (tilt-barrel) pistols when mated to appropriate CAM-LOK barrel adapters.
• The listed fit is Dead Air.

The CAM-LOK piston simplifies suppressor mounting on supported pistols by offering repeatable indexing, tool-installable prevailing torque, and a taper-lock interface to limit movement under cycling. Its materials and heat treatment emphasize durability and alignment precision to protect the suppressor internals and reduce maintenance caused by loosening. For users who prioritize quick deployment and robust attachment on range or competitive platforms, this piston is a focused upgrade to legacy direct-thread designs.
