Availability: In Stock
The Trijicon RMR Full Co-Witness Quick Release Mount is a Picatinny rail optic mount engineered for shooters who want their red dot sight perfectly aligned with their iron sights. Built from mil-spec 7075-T6 aluminum and finished in durable matte black, this full co-witness mount puts your RMR or SRO on the same sight picture as your backup sights—a setup favored by competitive shooters, defensive practitioners, and serious hunters who refuse to compromise on backup iron capability. The one-handed, tool-free mounting system means you can install or remove your optic in the field without fumbling for an Allen wrench.
Full co-witness height places the optical axis 1.384 inches above the rail for RMR models (1.625 inches for SRO), so both your red dot and irons stay in focus as you transition between them. Trijicon's Q-LOC technology ensures zero shift resistance and consistent return-to-zero performance, even after repeated mounting cycles. The low-profile design keeps your sight picture uncluttered while maintaining the rigidity you need for accurate shooting. Made in the USA and drop-tested to mil-spec standards, this mount handles hard use without flinching.
Whether you're building a duty rifle, a 3-gun competition gun, or a hunting platform, this mount solves the alignment problem cleanly. It's compatible with any Picatinny rail and works with both RMR and SRO footprints, giving you flexibility as your optics collection grows.

Yes. This mount is designed to fit any Picatinny rail and positions your RMR or SRO at full co-witness height so both your red dot and backup iron sights stay aligned in your field of view. You get true co-witness capability without choosing between optic and irons.
Yes, this mount accommodates both Trijicon RMR and SRO red dots. The height specifications differ slightly between the two (RMR sits at 1.384 inches full co-witness, SRO at 1.625 inches), so verify which optic you're running before mounting.
The one-handed quick release system requires no Allen wrench or additional tools. Tighten the mount by hand to secure it to your rail; Trijicon specifies a torque range of 12–16 in./lbs. with spring tension only, and up to 44–66 in./lbs. if you need maximum tightness with a torque wrench.
Trijicon's Q-LOC technology ensures your optic returns to zero when you remount it. This makes field swaps and maintenance fast and reliable, so you can trust your zero even after taking the mount on and off.
