USED Bravo Company MFG 1.93in Height A/T Optic Mount for Trijicon MRO Black BCM-OM-AT-272. Improving on Mil-Spec rail interfaces dating back over 30 years the BCM A/T mount delivers unprecedented zero retention on a properly mounted red dot optic. Low profile and snag-free BCM A/T Mounts are built with a minimal number of components - delivering a stronger component with less points of failure ready to take on dynamic and adverse settings. Each A/T Mount features multiple integral recoil lugs to mitigate recoil and counter recoil to preserve your zero and ensure no fail shots are placed where intended by the trained rifleman. Each 7075T6 billet mount is hard coat anodized per Mil-A-8625F. Additionally both the steel alloy clamp and nut are hardened with Nitride coating.
