Frequently Asked Questions

What is the primary benefit of the BCM A/T Optic Mount's Angled Torque system?

The Angled Torque (A/T) system in the BCM mount applies clamping force at an angle, directing all torque onto the rail. This creates a more durable connection and enhances the mount's ability to hold zero under recoil compared to traditional horizontal interfaces.

What are the correct torque specifications for the BCM A/T mounts?

For the BCM A/T Optic Mount, the recommended torque specification is 65 in-lb. For the BCM A/T Riser Mount, the specification is 40 in-lb. Using a torque wrench is essential for proper installation.

What optics are compatible with the BCM A/T Optic Mount?

The BCM A/T Optic Mount featured is designed with an Aimpoint Micro T2 footprint, making it compatible with optics like the Aimpoint Micro T2 and Aimpoint CompM5, which share this mounting standard.

Can BCM A/T Riser Mounts be used with the optic mount?

Yes, BCM A/T Riser Mounts are designed to be used in conjunction with other A/T mounts, such as the 1.93-inch optic mount. They can be stacked to achieve higher mounting heights or position magnifiers.
