Griffin Armament Piston Barrel Adapter .578x28 CAM-LOK - PI57828

This is a barrel adapter for Griffin Armament's CAM-LOK universal quick-detach piston attachment system, designed for .578x28 threaded barrels. The adapter features a forward taper surface that locks with the piston to reduce or eliminate baffle strikes, three 120-degree separated mounting positions for rapid mounting, and coarse top-cut threads for increased durability. Installation uses a 3/4-inch or 19mm wrench pattern socket wrench and requires compatible universal QD pistons (sold separately).
