LaRue Tactical QD Pivot Mount Tall Black. 725" centerline height-alignment...providing proper cheek-weld. With durability and simplicity in-mind the angled spring-tensioned pivoting arm rotates on a robust shaft. No buttons no switches no delicate places to fill with sand. You simply grab the optic one-handed pull back move it in-position release and you're good-to-go. Once it's in position it does not move unless you want it to. The design allows the Aimpoint 3X to fit over top of most flip-up rear sights. The LT755 shown fits 30mm bodies such as the Aimpoint 3X Magnifier. The mount is available by itself or as a Aimpoint 3X combo special. Both Mounts and Combo packages come complete with QD adjustment wrench vial of blue Locktite and Instructions. LT755 will not work with the MAKO magnifiers due to the rib that runs around the outside diameter. LT755-30T: This magnifier mount will properly align with the following LaRue mounts LT150 LT129 LT110 (mounted behind not piggyback) and LT659. This combo comes complete with QD adjustment wrench vial of blue Locktite and Instructions.
