MIDWEST MK2 RMR MOUNT 1/3 COWITNESS

Precision optics mounting requires hardware that won't shift under recoil or compromise your sight picture. This 1/3 cowitness design positions your red dot at the correct height above iron sights, letting shooters transition between aiming systems seamlessly. Whether you're building a rifle in Redwood City or anywhere else, proper mount selection matters. TacticCAL handles FFL transfer in Sunnyvale so you can focus on your setup.

Cowitness height and sight alignment

The 1/3 cowitness height places your red dot optic one-third of the way up your iron sight picture. This geometry keeps both aiming systems usable without forcing you to choose between them. Midwest Industries engineered this mount for RMR-pattern optics on AR-platform receivers. Installation is straightforward once you understand the mounting pattern and torque specs. Our staff can discuss mounting questions, and we handle all FFL transfer pricing transparently so there are no surprises. Visit our gun store in Sunnyvale for our full catalog.

Frequently asked questions

Does this mount work with all RMR-pattern red dots?

This mount is designed for RMR footprint optics. Verify your specific red dot uses the standard RMR mounting pattern before purchase. Most modern micro red dots follow this standard, but compatibility always depends on exact model specifications.

Can I install this mount without gunsmithing tools?

The MK2 RMR mount installs on standard Picatinny rail systems using basic tools. You'll need appropriate screwdrivers and a torque wrench for proper fastening. If you're unfamiliar with mounting procedures, consider consulting a qualified gunsmith.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Find gun store San Mateo at TacticCAL.
