Griffin Piston Barrel Adapter .578×28

The Griffin Armament piston barrel adapter provides a CAM-LOK quick-detach interface to convert compatible suppressors for use on Browning-style tilt-barrel pistols with .578×28 threads. The CAM-LOK (Covert Application Mount-Locking) system enables faster, more repeatable mounting compared with legacy single-piece direct-thread pistons. Constructed from corrosion-resistant 17-4 stainless steel with a durable QPQ nitride finish, the adapter is designed for repeated use and secure attachment.
