Trijicon MRO Levered Quick Release 1/3 Co-Witness Mount - Matte Finish

The Trijicon MRO Levered Quick Release 1/3 Co-Witness Mount is a purpose-built mounting system for the compact Trijicon MRO red dot sight. Built from matte-finished aluminum, this quick-release mount delivers the speed and repeatability serious shooters demand. The levered quick-release mechanism lets you mount or detach your optic in seconds without tools, making it ideal for shooters who run multiple rifles or need to swap between setups fast. The 1/3 co-witness height positions your MRO perfectly above the bore axis, allowing you to use standard iron sights or backup sights as a secondary aiming reference.

This is the go-to choice for AR platform rifles, tactical carbines, and duty-configured firearms. Whether you're setting up a home-defense rifle, a dedicated competition gun, or a modular platform you configure for different roles, this mount gives you the flexibility to move your sight between guns without losing zero or dealing with fiddly hardware.

Trijicon's reputation for durability under hard use backs every mount they produce. The aluminum construction is light enough for all-day carry, robust enough for rough handling, and finished in matte black to minimize glint and match most modern rifle platforms.

Frequently Asked Questions

What's the difference between 1/3 co-witness and absolute co-witness?

A 1/3 co-witness mount positions your MRO so that the red dot sits one-third of the way up your backup iron sight picture. This gives you a useful backup aiming reference while keeping the optic lower and less obstructed than an absolute (center) co-witness. Most shooters prefer 1/3 co-witness for red dots because it keeps the sight compact and doesn't require the optic to sit as high on the rail.

Will this mount work on any AR-15 or is it rifle-specific?

This mount fits any firearm with a standard Picatinny rail. It's most commonly used on AR platform rifles, but it will mount on any rifle, carbine, or handgun with a top Picatinny rail.

Can I move this mount between guns without losing zero?

The quick-release lever allows fast mounting and removal. However, like any removable mount, there can be slight zero shift when remounting. For rifles where you're moving the sight between guns, you may need to verify zero on each platform.
