Griffin Armament Piston Barrel Adapter 1/2×28

The Griffin Armament CAM-LOK piston barrel adapter provides a rapid, secure mounting interface for suppressors on browning-style (tilt-barrel) pistols. It replaces legacy single-piece direct-thread pistons with a patented CAM-LOK quick-attach system for faster, more repeatable installation. The adapter’s internal bore and forward-taper locking surface are designed to reduce common baffle and end-cap strikes while minimizing side concussion and visual disturbance. Finished in QPQ nitride over 17-4 stainless steel, the adapter is built for durability and frequent use.
