The Midwest Industries MK2 30mm RMR Cap in a 45-degree offset configuration (Midwest Industries part no. MIMK230RMR45) lets shooters running a magnified optic on an MK2 30mm mount add a Trijicon RMR-pattern red dot canted to the side for fast close-range transitions. Midwest Industries machines this offset cap to the same precision engraving and hard coat anodized 6061 aluminum finish as the rest of the MK2 lineup, so it installs and functions exactly like the standard-position caps while placing the RMR at 45 degrees off the top rail. That angle lets a shooter roll the rifle slightly to bring the red dot into view for close targets, then roll back to the magnified optic for distance, a setup favored by 3-Gun and tactical carbine competitors who need both capabilities on one gun.
