The Griffin Armament DUAL-LOK Tactical Compensator integrates 60 machined mounting position locking grooves, which is doubled by the mount's two locking positions, hence the double entendre DUAL-LOK. How is this achieved? The mounts' two locking positions are machined out of phase of one another by 3 degrees which provides the 120 effective locking positions and ensures a tightly mounted and locked suppressor. When the suppressor is installed, only one of the two positions will generally function by allowing the spring to push the locking collar rearward over the splines.The DUAL-LOK Tactical Compensator incorporates vast R&D resources from years of testing low concussion devices but also adds to it with new technology. Billet machined from 2 pieces of 17-4 Stainless steel, this device is laser welded together to provide the largest possible internal expansion chamber which reduces concussion as effectively as possible. The benefits of laser welding include a much deep...
