The Trijicon MRO Full Co-Witness Mount is a precision accessory designed to integrate your MRO red dot sight with AR-15 style rifles while maintaining proper sight picture alignment. If you're running backup iron sights on your rifle, this full co-witness mount positions your optic at the correct height so your BUIS (backup iron sights) align directly behind the red dot reticle—giving you redundant aiming points in the same sight picture without one interfering with the other. It's the go-to choice for shooters who prioritize reliability and want iron sights as a failsafe on a primary optic platform.
Co-witness height matters more than most shooters realize. A full co-witness puts your backup irons and your MRO reticle on the same optical plane, so you can sight through both simultaneously if needed. This setup is especially valuable in duty, competition, or serious defensive rifle work where a optic failure means you can transition instantly to iron sights without breaking your shooting position or zeroing in again. The full co-witness geometry is purpose-built for that seamless transition.
Trijicon engineered this mount to work specifically with the MRO platform, ensuring a solid, repeatable interface that won't loosen under recoil. It's finished in black tactical hard coat to match modern rifle setups and resists corrosion and wear. Whether you're building a patrol rifle, a precision AR-15, or a duty-ready setup, this mount gives you the height and reliability serious shooters expect.

Frequently Asked Questions
What does full co-witness mean, and why does it matter?
Full co-witness means your backup iron sights and your red dot reticle are positioned at the same optical height. When you look through the optic, your BUIS will be perfectly centered in the sight picture behind the reticle. If your optic fails or is damaged, you can transition to irons instantly without adjusting your grip or sight picture.
Will this mount work with my MRO on any AR-15?
This mount is designed for AR-15 style rifles and works with the Trijicon MRO. Compatibility with specific upper receivers or handguard configurations may vary, so verify fitment with your exact setup before purchase.
Can I use a lower-third co-witness setup instead?
Trijicon offers multiple mount heights for the MRO. This product is specifically the full co-witness model. If you prefer your irons in the lower third of your optic view, you would need a different mount height option.
