Bcm At Optic Mount Lower 1/3 - For Trijicon Mro

The Bravo Company AT Optic Mount for Trijicon MRO is a precision 1/3 co-witness mounting solution engineered for shooters who demand absolute zero retention and reliability under stress. Built on Bravo Company's proprietary Angled Torque (A/T) system, this mount applies triangulated clamping force to the Picatinny rail—delivering roughly twice the holding power of conventional horizontal clamps—ensuring your red dot stays zeroed through recoil, movement, and dynamic tactical applications.

Machined from 7075-T6 billet aluminum and finished with hard coat anodizing per military spec (Mil-A-8625F), the AT mount pairs durability with minimal weight and profile. A hardened, nitrided steel clamp and serrated locking spring-washer prevent torque loss in the field, while multiple integral recoil lugs work to preserve zero shot after shot. Low-profile and snag-free by design, this mount is optimized specifically for the Trijicon MRO optic, positioning it at lower-1/3 co-witness height for faster target acquisition and enhanced sight picture flexibility.

Bravo Company engineered this mount with fewer moving parts than legacy designs, reducing complexity and points of failure—a philosophy that extends across their entire optics mount lineup. The result is a proven platform trusted by shooters who run their rifles hard, whether in competition, patrol, or hunting scenarios where a lost zero isn't an option.

Specifications

Frequently Asked Questions

Is this mount compatible with my Trijicon MRO?

Yes—this BCM AT mount is specifically optimized for the Trijicon MRO and positions it at lower-1/3 co-witness height on your rifle.

What's the benefit of the Angled Torque clamp design?

The A/T clamp uses angled, triangulating force to lock onto the Picatinny rail. Compared to older horizontal clamp designs, it delivers approximately twice the clamping force, which translates to superior zero retention through recoil and dynamic use.

Will this mount hold zero under heavy recoil?

The mount features multiple integral recoil lugs engineered to mitigate recoil and counter-recoil, working to preserve your zero. The serrated locking spring-washer also prevents the hardware from loosening under field conditions, ensuring the clamp maintains its torque.

What is lower-1/3 co-witness and why does it matter?

Lower-1/3 co-witness positions your red dot optic so that your rifle's iron sights (front and rear) appear in the lower third of the sight picture when looking through the optic. This height gives you flexibility to use the optic as your primary aiming reference or quickly reference iron sights as a backup without moving your head position.
