The CAM-LOK® (Covert Application Mount - Locking) is a universal QD piston system comprised of two parts, the male barrel adapter and the female piston OR now available, the CAM-LOK® Universal Direct Thread Adapter.  This product page is for the CAM-LOK® Universal 1.125 Direct Thread Adapter (bronze colored part that is installed in the booster housing). This direct thread adapter takes the place of the piston and spring.  

These CAM-LOK® Universal 1.125x28 Direct Thread Adapters allow you to convert 1.125x28 threaded Griffin suppressors in their shortest configuration to receive CAM-LOK™ barrel adapters. Adapters also allow you to convert the Griffin Optimus Micro.

The Griffin Armament CAM-LOK® interface affords the user the ability to convert the suppressor to a much faster and more secure mounting solution on fixed barrel pistols. This system provides a rapid, secure attachment to the host pistol.

    Very nicely machined Cam-Lok adapter for my Rugged Suppressor. Have not used it yet though cuz I'm still playing the waiting game.
