The GRIFFIN UNIVERSAL PISTON CGS is the piston component of Griffin Armament’s CAM-LOK (Covert Application Mount-Locking) universal QD mounting family. It is the bronze-colored piston installed inside the suppressor and provides a rapid, secure attachment method for CAM-LOK barrel adapters. The piston accepts a 3/4-inch socket for installation with prevailing torque and is engineered to reduce common baffle and end-cap strikes associated with legacy direct-thread pistons.
Product Specifications
This item is the piston portion of the system and is described as the bronze-colored universal QD piston installed in the suppressor.
The mounting interface uses a patented CAM-LOK (Covert Application Mount-Locking) attachment system.
The piston provides three mounting positions separated by 120 degrees for rapid, repeatable alignment.
Installation accepts a 3/4-inch socket wrench and can be torqued to prevailing torque values.
The internal taper surface provides a taper-lock engagement that reduces the incidence of baffle and end-cap strikes.
The piston is compatible with Universal QD piston barrel adapters (sold separately), enabling cross-platform use when paired with CAM-LOK adapters.
Manufacturing tolerances are held to Griffin Armament’s standards for squareness and concentricity to minimize point-of-impact shift.
The piston is produced from 17-4 stainless steel and is H900 heat treated for improved durability and wear resistance.
The design aims to have a total system weight identical to legacy direct-thread pistons when used with matching adapters.
The manufacturer is listed as Griffin Armament.
The model name is GRIFFIN UNIVERSAL PISTON CGS.
The listed UPC is 791154085066.
Whether you are preparing a pistol for frequent range use or competition where repeatable, secure suppressor mounting matters, this CAM-LOK piston provides a mechanically robust alternative to hand-tightened direct-thread pistons. Its taper-lock engagement and indexed mounting positions are designed to make suppressor attachment quicker and more consistent during routine use.
