Capability in the face of the unexpected and catastrophic, the BCM A/T Mount is built in anticipation of a ''no fail'' shot that will save another human life.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.A/T (Angled Torque) mounts employ angled torque through a patented clamp which applies triangulating force to create a stronger and more reliable lock up of the mount onto the end users rail. To retain the hardware in field conditions, this system uses a serrated locking spring-washer to prevent the loss of torque on the shaft nut.
