MIDWEST MK2 RMR MOUNT COWITNESS$89.95
Availability: In Stock
The Midwest Industries MK2 RMR Mount with 1/3 cowitness is a precision-engineered optic mount built for shooters running red dot or reflex sights on their AR platform rifles. If you're pairing a compact red dot with a magnified optic or iron sights, this mount positions your RMR at the perfect height to use both systems simultaneously—a huge advantage in the field or on the range. Midwest engineered this mount to deliver the accuracy and durability that matters when your setup has to perform under real conditions.
The MK2 RMR mount is machined from hard-coat anodized 6061 aluminum for a finish that'll weather years of use without degradation. The clamps themselves are 4140 heat-treated steel—serious material for a serious job—and integrated Torx hardware keeps everything locked down tight. Every mount is precision-machined to preserve your zero shot after shot, and the included Midwest Industries Optic Mount Tool takes the guesswork out of installation and adjustment. Made in the USA with a lifetime warranty, this isn't a mount you'll ever need to replace.
The 1/3 cowitness height is the sweet spot for most AR setups. You get a lower-third sight picture through your red dot while maintaining zero reference to iron sights or a secondary optic positioned higher on your upper receiver. This mount solves the real problem: consolidating multiple aiming systems without compromise. Whether you're hunting, running a practical rifle course, or building a home defense carbine, the MK2 RMR mount handles the job with the precision and reliability Midwest Industries is known for.

1/3 cowitness positions your RMR at the lower-third sight line. This height lets you aim through the red dot while keeping iron sights or a magnified optic mounted higher on your upper receiver in your peripheral view. You get two aiming systems without buying a second gun—ideal for hunters and shooters who want a backup sight reference or who run multiple optics in different scenarios.
The MK2 RMR mount is engineered for RMR-pattern optics. If your red dot uses the RMR footprint, this mount will work. Midwest also makes MK2 mounts for other patterns (Acro, T2, and micro dot clones), so verify your optic's mounting pattern before ordering.
The MK2 RMR Mount includes the mount itself and the Midwest Industries Optic Mount Tool, which helps with proper installation and optic adjustment.
Yes. The MK2 is precision-machined specifically for return-to-zero performance, and the 4140 heat-treated steel clamps with integrated Torx hardware create a rock-solid grip on your optic. Combined with the lifetime warranty, you can count on consistent zero.
