Midwest MK2 QD RMR Mount Cowitness

The Midwest MK2 QD RMR Mount Cowitness is a precision quick-detach optic mount engineered for shooters who demand reliable, tool-free mounting of their red dot sights. Built on Midwest Industries' reputation for American-made quality, the MK2 combines a patented QD lever system with the rock-solid repeatability serious shooters expect—whether you're running a dedicated RMR cowitness setup on your AR, zeroing at the range, or carrying for duty use.

The signature feature here is the QD mechanism itself. Unlike generic lever mounts, the MK2's patent-pending design from Elite Defense delivers the smoothest engagement and disengagement in the market, with fully adjustable lever tension that requires no tools. That matters when you're swapping optics in the field or optimizing fit to your specific rail—every gun's receiver has its quirks, and this mount adapts to yours without compromise. The multi-faceted adjustment nut gives you granular control to dial in exactly the tension your setup needs, and it stays dialed in. Zero loss between cycles. The clamping surfaces are precision-engineered to protect your rail from damage or marring, a detail that separates a $200 mount from a $50 knockoff.

Built from 6061 aluminum with hard-coat anodize, the MK2 is finished to last. The premium engraving throughout signals the attention to detail you'll feel when you handle it. Midwest includes their optic adjustment tool, so you can true your sight to the mount out of the box. Available in multiple height and reticle configurations—Low, Lower 1/3 Cowitness, Absolute Cowitness, and NV 2.26" height—and compatible with RMR, Acro, T2, or Micro dot pattern sights, so you can match your platform and mission. Made in the USA with a lifetime warranty backing every unit.

Frequently Asked Questions

Will this mount work with my RMR? What other optics are supported?

The Midwest MK2 QD mount is offered in multiple optic-specific configurations: RMR, Acro, T2, and Micro dot pattern. Order the version that matches your sight. Replacement optic-specific scope ring caps are available separately if you need to switch patterns later.

What cowitness height should I choose?

Cowitness height depends on your backup iron sights and sight picture preference. Options include Low, Lower 1/3 Cowitness, Absolute Cowitness, and NV 2.26" height. Lower 1/3 is the most common for AR platforms with standard A-frame or BUIS; Absolute Cowitness aligns the dot with iron sight posts. Choose based on your iron sights and shooting style.

Can I adjust the QD lever without tools? Will it fit rails that aren't Mil-Spec?

Yes—the QD lever is fully adjustable with no tools required. The multi-faceted adjustment nut lets you dial in exact tension to accommodate rails that aren't machined to Mil-Spec tolerances, so you're covered whether your upper is tight or has a bit of slop.

What comes in the box?

The Midwest MK2 QD RMR Mount Cowitness includes the mount and the Midwest Industries Optic Mount Tool for optic adjustment and fitting.
