Product Info for American Defense Manufacturing Aimpoint Comp M4 Mount 1 Piece Lower 1/3rd Co-Witness

Nothing says "no-nonsense" like the American Defense Manufacturing Aimpoint Comp M4 Mount 1 Piece. These Red Dot Sight Mounts from the trailblazers at American Defense Manufacturing feature a 1 piece design that brings a level of quality rarely found in red dot mounts. With an understated beauty, the American Defense Manufacturing Aimpoint Comp M4 Mount 1 Piece features a Mil-Spec hard anodized finish. For the most part, these will fit snugly on your flattop upper receiver. However, they do require a slight gunsmithing to bring the mount into perfect alignment which can take up to 3 hours. Thankfully, the American Defense Manufacturing Aimpoint Comp Mount 1 Piece solves all of those issues by clamping down on the sight instead of the more common hook and loop methods. No more having to rely on a wobbly adapter to get the Red Dot Sight Mount that just doesn't belong. Equip the American Defense Manufacturing Aimpoint Comp Mount 1 Piece for a level of quality mounting for your favorite Comp M4 on your next mission.image
