Midwest Industries MK2 30mm RMR Scope Ring Cap

The Midwest Industries MK2 30mm RMR Cap (Midwest Industries part no. MIMK230RMR) is an optic-specific replacement scope ring cap built for shooters running an MK2 30mm scope mount who want to add a Trijicon RMR-pattern offset or top-mounted red dot. Midwest Industries designed the MK2 line around interchangeable, optic-specific caps rather than a one-size-fits-all design, so upgrading or changing optics does not mean replacing the entire mount. Machined to match the precision engraving and hard coat anodized 6061 aluminum finish of the rest of the MK2 lineup, this cap installs with the included Torx hardware for a secure, repeatable mount. It is purpose-built for the RMR footprint, giving shooters who run this widely supported pattern a clean, factory-matched way to add that optic to an existing MK2 30mm mount.
