The Griffin Armament CAM-LOK Piston Barrel Adapter with .578x28 threading delivers a faster, more secure mounting solution for suppressors on browning-style action pistols than legacy direct thread systems. Its patented CAM-LOK universal QD piston attachment system offers three mounting positions spaced 120 degrees apart for rapid attachment, while the forward taper surface locks in place to reduce baffle and end cap strikes.

Coarse threads are top cut for increased durability and wear resistance, and the QPQ Nitride finish provides a durable black finish. The adapter uses a 3/4" or 19mm wrench pattern for secure installation and is compatible with Universal QD pistons sold separately, maintaining identical weight to legacy direct thread pistons while reducing side concussion compared to blind muzzle designs.
