Midwest Industries MK2 RMR Cap Features The Midwest Industries MK2 RMR Cap is built as a direct-fit optic cap for the Trijicon RMR footprint letting shooters configure their MK2 scope mount for RMR-pattern red dot sights. Machined from hardcoat anodized 6061 aluminum the cap is engineered to hold up to a lifetime of service while keeping the mount s overall weight manageable. Because the MK2 series is built around a modular cap system shooters can swap optic-specific caps as their equipment needs change rather than replacing the entire mount. This modularity reflects the design philosophy behind the broader MK2 lineup which emphasizes precision durability and adaptability. At 30mm in tube diameter and finished in a matching black hard anodized coating the RMR cap integrates cleanly with the rest of the MK2 mount for a consistent professional appearance. Precision machining on every MK2 component is intended to guarantee reliable return-to-zero performance and the RMR cap is manufactured to the same tight tolerances as the rest of the series. Backed by the Midwest Industries Lifetime Warranty and proudly made in the USA this cap gives RMR-footprint optic users a dependable way to integrate their sight with an MK2 mount. For shooters already running an MK2 scope mount this cap extends compatibility to one of the most widely used red dot footprints on the market.
