Midwest Industries MK2 Co-Witness QD RMR Features The Midwest Industries MK2 mount uses a patented QD lever from Elite Defense that is the smoothest functioning quick-detach lever in its class allowing shooters to remove and reattach their optic without tools. A multi-faceted adjustment nut lets the lever tension be fine-tuned to fit rails not machined to strict Mil-Spec tolerances ensuring a snug rattle-free fit across various rail brands. The clamping mechanism grips securely without coining or damaging the rail surface protecting the host rifle over repeated mounting cycles. Precision machining throughout the mount ensures optimum return to zero performance every time the optic is reattached. Machined from hard coat anodized 6061 aluminum with steel components this mount is built in the Black finish for long-term durability against the elements and daily handling. Set at a co-witness height and cut to an RMR footprint it positions a red dot sight in line with standard AR iron sights for a fast backup sighting option. Measuring 2 inches long and 2.26 inches tall while weighing just 2.30 ounces it adds minimal bulk to the top of a rifle. Midwest Industries includes their own optic mount tool with the MK2 giving shooters everything needed to fit and adjust their optic properly.
