This is the standard QD mount for the Trijicon MRO™ (Miniature Rifle Optic) allowing 1/3 cowitness with the Iron Sights on M4 Carbine and AR-15 Flattops. Like all LaRue mounts, they are precision-machined out of bar-stock aluminum and matte black anodized to provide a durable non-reflective surface finish. The locking LaRue Speed Lever provides outstanding return to zero; the optic can be removed, and replaced, without loss of zero. Guaranteed.
Each mount comes complete with replacement mounting screws with wrench, QD adjustment wrench, vial of blue Locktite and Instructions.
