Griffin Armament Piston Adapter 13.5X1 LH

The Griffin Armament Piston Barrel Adapter 13.5X1 LH provides a CAM-LOK (Covert Application Mount-Locking) quick-detach piston interface designed to convert compatible suppressors from direct-thread mounting to a faster, more secure piston system. The adapter uses a three-position, 120-degree mounting pattern and a forward taper surface to engage the interfacing piston. Constructed with 17-4 stainless steel and finished with QPQ nitride, the adapter is intended for use on tilt-barrel (Browning-style) pistols and other platforms that accept the specified thread pattern.
