Griffin Armament Piston Barrel Adapter 1/2×28

The Griffin Armament Piston Barrel Adapter 1/2×28 provides a CAM-LOK piston interface that converts compatible suppressors to a faster, more secure mounting solution for Browning-style (tilt-barrel) pistols. The adapter’s forward taper surface locks with an interfacing piston to reduce or eliminate common baffle and end-cap strikes observed with direct-thread pistons. It is compatible with Griffin’s Universal QD pistons (sold separately) and is designed to maintain the weight profile of legacy direct-thread pistons. Finished with QPQ nitride on durable 17-4 stainless steel, the adapter supports straightforward installation and robust service life.
