Griffin Armament | Universal CAM-LOK Piston | SIG SRD

The Griffin Armament CAM-LOK universal piston is the piston component used with the CAM-LOK® mounting system to enable rapid, repeatable attachment of compatible suppressors to host pistols. This listing is for the piston portion (the bronze-colored part installed in the suppressor) and is designed to work with CAM-LOK barrel adapters sold separately. The CAM-LOK interface reduces the risk of inadvertent loosening that can occur with legacy single-piece direct-thread pistons and supports secure attachment under slide cycling.

Typical applications include suppressed range training and competition shooting where fast attachment and reliable concentricity are priorities, and multi-host suppressor setups where interchangeability between adapters improves logistics.

Product Specifications

• The product is the piston component of the CAM-LOK® universal QD piston attachment system.
• This listing is for the piston (bronze color part installed in the suppressor).
• The CAM-LOK system provides 3 mounting positions spaced 120 degrees apart for rapid alignment and installation.
• The interface uses an internal taper surface designed to lock with compatible barrel adapters and reduce baffle or end cap strikes.
• The piston is compatible with any pistol mounted with a 3-lug CAM-LOK barrel adapter (adapter sold separately).
• The piston is intended to provide a faster and more secure attachment on Browning-style (tilt barrel) pistols than legacy direct-thread pistons.
• The piston assembly supports installation with a 3/4″ socket wrench to achieve prevailing torque.
• The piston is stated as H900 heat treated to improve durability and wear resistance.
• The listed material for the piston is 17-4 stainless steel.
• The product appearance is described as a bronze color piston component.
• The design intent is to maintain identical total system weight compared to legacy direct-thread pistons for balance preservation.
• Griffin Armament reports manufacturing accuracy for mating diameters and interfacing geometry held to tool-quality tolerance for alignment and minimal POI shift influence.
• The piston family is designed for interchangeability with compatible CAM-LOK barrel adapters across supported suppressors.
• The listed weight value is .15.
• The UPC is 791154085196.

Engineered to simplify mounting and improve repeatability, this CAM-LOK piston is a practical component for shooters who use suppressors across multiple host pistols or who require a more secure QD interface than traditional direct-thread pistons provide. The combination of H900 heat treatment and 17-4 stainless construction addresses wear resistance while the three-position taper-lock interface prioritizes quick deployment and concentricity for range training and competition use.
