The Griffin Armament CAM-LOK (Covert Application Mount-Locking) Patented Universal QD piston attachment system delivers rapid, secure mounting with three positions spaced 120 degrees for fast, repeatable setup and minimized downtime. A forward taper surface locks firmly in place with interfacing piston, dramatically reducing or eliminating common baffle and end cap strikes while maintaining a compact silhouette. Coarse threads are top cut to boost durability and wear resistance, and the 3/4 inch or 19mm wrench pattern allows secure, easy installation with a socket wrench. Compatible with Universal QD pistons (sold separately), this adaptor integrates into a quiet, balanced system that preserves the internal bores side concussion advantages versus traditional blind muzzle designs, helping to maintain visual and auditory integrity during operation. Crafted from 17-4 stainless steel and finished with a durable QPQ Nitride coating for a low-reflectance, hard-wearing surface, the CAM-LOK adaptor mirrors the weight of legacy direct-thread pistons, ensuring consistent performance. It also supports Universal Carry Comp and other suppressor mounting devices, making it a versatile, high-integrity option for precision shooters seeking streamlined versatility.
