The Knight’s Armament anti-cant device is a rail-mounted bubble level that helps precision shooters confirm the rifle is level before they break a shot. KAC built a small bubble level into an aluminum base that sits low enough to be used under most optics. It attaches to any M1913 Picatinny rail surface with a screw and clamp arrangement. Canting a rifle shifts the point of impact at distance, so a visible reference at the rail gives a shooter something to check on every setup.
