The Midwest Industries MK2 RMR Mount (brand part no. MIMK2RMRCO) sets a Trijicon RMR-footprint red dot at full, absolute co-witness height, lining the dot up directly over standard-height AR iron sights. It bolts to a Picatinny or 1913 rail as a fixed mount rather than a quick-detach design, giving a solid, repeatable zero with nothing to work loose. It is machined as part of Midwest’s MK2 mount series, matching the fit and finish of the rest of the lineup. Full co-witness suits shooters who want their irons to line up exactly behind the dot as an instant backup sighting system.
