The Trijicon MRO 1/3 Co-Witness Quick Release Mount is a purpose-built accessory for shooters who want to keep their backup iron sights in play while running a modern reflex optic. This compact, tool-free mount clamps to any Picatinny rail and positions your MRO red dot at 1/3 lower co-witness height—meaning you can see through the sight picture to your iron sights underneath. If you're running a rifle platform that benefits from both digital and mechanical aiming solutions, this mount lets you have both without compromise.

Built from 7075 T6 aluminum alloy, the mount weighs just 1.8 oz, so it won't bloat your setup. The one-handed quick-release lever is intuitive: flip it to detach your MRO and mount as a unit in seconds. No tools, no fiddling. That speed matters on the clock, in the field, or when you want to migrate your sight between rifles. The return-to-zero design ensures that when you reinstall the mount, your zero stays put—a real time-saver if you rotate optics across multiple platforms or need to swap rifles mid-session.

This is the same mount that ships with Trijicon's MRO Patrol, so you get the same rugged, proven design trusted by professionals and serious shooters. If co-witness capability and modular flexibility are part of your rifle philosophy, this mount delivers both in a lightweight, reliable package.
