The Midwest MK2 30MM RMR Cap is an optic-specific mounting adapter designed to crown your MK2 QD scope mount with a red dot sight. If you're running a Midwest MK2 base and want to add an RMR, Acro, T2, or compatible micro red dot as a primary or backup optic, this cap gives you a clean, integrated platform. The MK2 system is built on the philosophy that your mount should work with your gear—not force you to compromise—so Midwest engineered this cap to deliver solid performance without the guesswork.
Built from hard-coat anodized 6061 aluminum and manufactured in the USA, the RMR Cap is precision-machined to maintain zero shot after shot and comes with premium Torx hardware for secure mounting. The cap includes torque spec engravings right on top, eliminating the need to hunt down manual specs during setup. If you're familiar with Midwest's approach to mounting solutions, you know they focus on reliability and user control—this cap follows that same ethos. Just remember that taller scope turrets on your primary optic can sometimes limit your view through certain red dot patterns, so plan your setup accordingly.
Installation is straightforward, and the included Midwest Industries Optic Mount Tool helps with any adjustments needed during fitting. Whether you're building a rifle for hunting, 3-gun, home defense, or duty work, this cap lets you add optical redundancy or speed up target acquisition without swapping your entire mount system.
