MIDWEST MK2 34MM RMR 45 OFFSET BLK

Offset mounting systems solve the problem of co-witnessing iron sights with your primary optic without sacrificing sight picture. The Midwest Industries MK2 34mm RMR mount delivers that solution with a 45-degree angle that keeps your backup sights functional. Whether you're picking up a new optic or transferring one through our FFL transfer in Sunnyvale, this platform handles the geometry correctly.

45-Degree Angle Design and Zero Retention

The 45-degree offset positions your optic out of the sight line while maintaining enough clearance for reliable transitions between primary and backup aiming references. Midwest Industries built this mount with tool-free installation in mind—no gunsmithing required. The rigid attachment prevents drift during recoil cycles, which matters whether you're running duty loads or practice ammunition. Shooters working with PC §32100 exempt revolvers often pair offset systems with secondary optics for enhanced versatility. TacticCAL is your local gun shop in the Bay Area.

Frequently asked questions

Will this 45-degree offset mount work with my RMR optic?

Yes. The MK2 is specifically designed to accept RMR-pattern optics. The 34mm mounting surface accommodates the footprint, and the 45-degree angle keeps your co-witness sight line clear for rapid transitions.

What rail systems does the Midwest Industries MK2 attach to?

The mount uses a picatinny rail interface, so it fits any MIL-STD-1913 rail. Check your upper receiver or handguard to confirm picatinny compatibility before ordering.
