Trijicon MRO 45° Offset Quick Release Mount - Matte Finish

The Trijicon MRO 45° Offset Quick Release Mount delivers a proven co-witness solution for shooters who want their red dot optic working in concert with iron sights. Built from mil-spec 7075-T6 aluminum and engineered to survive hard drop testing, this mount pairs rock-solid durability with the speed and simplicity of tool-free, one-handed installation. Whether you're running a modern carbine with backup iron sights or building a versatile patrol rifle, the MRO mount gets your optic into the fight fast and keeps it there.

The 45° offset geometry lets you mount your MRO to the side of the rail, leaving your upper receiver and handguard clear for lights, lasers, or other gear. This mounting position also means you're not sacrificing your co-witness alignment—the aiming dot sits right at the top of your iron sight post when both are in use, so you can transition between optic and irons without re-aiming. Q-LOC Technology ensures repeatability: mount it, use it, remove it, remount it, and return to zero is maintained. The low-profile, lightweight design won't burden your rifle or slow your movement.

Trijicon engineered this mount to work on any Picatinny rail, so compatibility across platforms is straightforward. Torque specs are generous—spring tension alone holds it, but you can cinch it down to 44–66 in./lbs. if you want belt-and-suspenders security. The matte finish resists glare and blends into modern rifle aesthetics without fuss.

Frequently Asked Questions

Will this mount work with flip-up iron sights?

Yes. The full co-witness height is designed to position your MRO aiming dot at the top of the iron sight post, making it ideal for use with pop-up backup sights. When both are in use, you maintain proper sight picture and can transition between optic and irons.

Do I need tools to install or remove this mount?

No. The MRO 45° Offset mount features tool-free, one-handed installation and removal. Q-LOC Technology preserves zero even after you've taken it off and reinstalled it, so you can swap it between rifles or remount without re-zeroing.

What rail systems is this mount compatible with?

The MRO 45° Offset mount works on any standard Picatinny rail, making it compatible across AR-15s, AR-10s, and most modern tactical and hunting rifles with mil-spec rails.

How tight should I torque this mount to the rail?

Spring tension alone will secure the mount, but Trijicon specs allow torquing between 12–16 in./lbs. for spring tension only, or up to 44–66 in./lbs. if you want maximum security. Always verify zero after installation regardless of torque method.
