The Leap is the strongest Trijicon MRO Quick-Detach mount we've ever tested.We put a variety of QD mounts on a digital test stand, capable of exerting up to 1500lbs of force, and analyzed load versus displacement data for each. We then used everything we learned from these tests to refine our original design, culminating in the Leap; a quick-detach mount that is both the lightest and strongest on the market today. Fits: Trijicon MRO, MRO HD, MRO Patrol
