Trijicon RMRcc Full Co-Witness Mount with Q-LOC System

The Trijicon RMRcc full co-witness mount with Q-LOC System is a compact, quick-release optic mount engineered for shooters running the Trijicon RMRcc on AR platforms and other rifles with Picatinny rails. This mount aligns your RMRcc optic at the same height as your backup iron sights, positioning the red dot at the top of the iron sight post—a setup favored by tactical shooters, competition riflemen, and hunters who want a proven co-witness configuration without sacrificing sight picture versatility.

Built from mil-spec 6061-T6 aluminum and drop-test rated for durability, the Q-LOC mount combines a low-profile footprint with automatic retention that keeps your optic secure through hard use. The tool-less, one-handed mounting design means you can deploy or swap your RMRcc in seconds, and the snag-resistant knob minimizes snagging on gear or clothing—practical details that matter in the field or at the range.

Return-to-zero repeatability is built in, so removing and remounting your optic won't cost you zero. The precision-cut dimensions ensure a tight, wobble-free fit on any standard Picatinny rail, and the quick-release lever gives you the flexibility to transition between setups or run your rifle irons alone when needed. Whether you're building a duty rifle, a precision hunting rig, or a dedicated range gun, this mount handles the job with the straightforward reliability Trijicon is known for.

Frequently Asked Questions

What does "full co-witness" mean for this RMRcc mount?

Full co-witness means the RMRcc optic sits at the same height as your backup iron sights. When you look through the rifle, the red dot appears at the top of the iron sight post, allowing you to use either sighting system while maintaining a unified sight picture. This setup is popular for tactical rifles and hunting builds where iron sights serve as a backup.

Is this mount compatible with flip-up iron sights?

Yes, this full co-witness mount is designed to work with flip-up iron sights. The co-witness height makes it an ideal pairing for raised or aftermarket flip-to-side backup sights.

What makes the Q-LOC system different?

The Q-LOC system combines quick-release functionality with automatic retention and a snag-resistant knob. It allows one-handed, tool-less mounting and removal while keeping your optic securely seated on the rail. The quick-release design means you can swap or stow your RMRcc in seconds without tools.

Will my zero shift if I remove and remount the RMRcc on this mount?

No. This mount features return-to-zero design, so removing and remounting the optic will not affect your zero, provided the mount remains on the rail.
