The FAST FTC PA magnifier mount uses a force-to-overcome mechanism, stowing the magnifier below the optical sight plane and within the footprint of the weapon's receiver when not in use. UNITY's FTC (flip-to-center) technology cancels the flip-to-side placement of legacy products, eliminating snag hazards and occlusion of sight pictures when stowed. The FAST FTC PA was designed for the Primary Arms Micro Magnifier and comes standard with a low-profile integrated FAST QD Lever. RSR -
