Griffin Armament CAM-LOK Universal Piston | Osprey

The Griffin Armament CAM-LOK universal piston is the piston component (bronze-color part) used with CAM-LOK barrel adapters for rapid, secure QD mounting of compatible pistol suppressors. This listing is for the piston only; barrel adapters are sold separately. The CAM-LOK system converts legacy direct-thread pistol pistons to a three-position QD interface that minimizes inadvertent loosening during slide cycling.

Typical applications include range/target shooting with a suppressed pistol and competition stages where fast, repeatable suppressor attachment is required. It is also suited for users who rotate a single suppressor among multiple host pistols via adapter interfaces.

Product Specifications

• The part is the CAM-LOK piston (bronze-color piston installed in the suppressor).
• The item is piston only; barrel adapters are sold separately.
• The interface is the patented CAM-LOK (Covert Application Mount-Locking) universal QD piston attachment system.
• The piston offers three mounting positions 120 degrees apart for rapid orientation and attachment.
• The mounting interface uses an internal taper surface that locks with CAM-LOK barrel adapters to reduce baffle and end-cap strikes.
• The piston supports installation with a 3/4-inch socket wrench for prevailing-torque attachment.
• The material is specified as 17-4 stainless steel in the source description.
• The piston receives H900 heat treatment for improved durability and wear resistance.
• The design maintains a total system weight identical to legacy direct-thread pistons according to the manufacturer text.
• The piston is compatible with any pistol fitted with a 3-lug CAM-LOK barrel adapter that accepts this piston family.
• The piston can be attached or detached in any one of three 120-degree positions ensuring consistent indexing.
• The manufacturer states that mating diameters and interfacing geometry are machined in a single operation for tool-quality accuracy.
• The product description reports the recorded weight as .15 (unit not specified in source data).
• The UPC is 791154085189.

The CAM-LOK piston brings a faster, more secure mounting option to pistols using CAM-LOK barrel adapters. Its taper-lock geometry and tool-installed prevailing torque reduce the need to retorque between sessions and aim to lower the risk of baffle or end-cap impact when compared to legacy hand-tightened direct-thread pistons. Durable materials and H900 heat treatment are used where specified to improve service life.
