Description
A levered, quick-release lower 1/3 co-witness mount that lets Trijicon MRO users detach and remount the optic quickly while keeping return-to-zero accuracy.
The Trijicon MRO Levered Quick Release Lower 1/3 Co-Witness Mount is built from aircraft-grade aluminium and is Mil-Spec drop-test rated, with an intuitive lever-locking design finished in Matte Black Anodized.
The lever can be locked to the front or the rear, making the mount fully ambidextrous, and its paddle includes an expanded grip zone for quick, simple mounting and removal. A through-hole in the lever also allows the optic and mount to be tied down with paracord for extra security in demanding conditions.
The mount offers return-to-zero capability on any Picatinny rail, and its lower 1/3 co-witness height positions the MRO higher than back-up iron sights for a clearer field of view, while keeping those iron sights visible in the lower third of the optical window as a backup.
Key features
- Ambidextrous lever lock — The locking lever can be set to the front or the rear, so the mount works equally well for left- and right-handed shooters.
- Expanded grip zone — An enlarged paddle area on the lever makes attaching and detaching the optic quick and simple.
- Paracord tie-down hole — A through-hole in the lever lets the optic and mount be tied down with paracord for extra security in combat or extreme conditions.
- Return-to-zero quick release — The mount returns the optic to zero on any Picatinny rail after it is removed and remounted.
- Lower 1/3 co-witness height — At 1.6 in. (40.64mm) above the rail, the mount positions the MRO higher than back-up iron sights while keeping them visible in the lower third of the optical window.
- Rugged aluminium housing — The housing is machined from aircraft-grade aluminium and is Mil-Spec drop-test rated, finished in Matte Black Anodized.
Typical applications
- Mounting a Trijicon MRO on a Picatinny-rail rifle where quick, repeatable removal and remounting of the optic is needed.
- Setups that keep back-up iron sights visible for use alongside the red dot.
- Environments where the optic and mount benefit from being tied down for extra security, such as combat or extreme conditions.
