BT6569ML / BT6569ML-NC: Atlas CAL Upgrade Mount

New product

The BT6569ML and BT6569ML-NC are current production CAL mounts that provide 63 degrees of Cant. Additional Cant is considered an upgrade (see illustrations to determine which mount you have). The additional degrees of Cant was requested by a member of the SOF community and longtime user of B&T products.

The BT6569ML Mount is the standard two-screw mount with the 63 degree Cant upgrade part for any model of CAL or Super CAL Atlas Bipod.

The BT6569ML-NC Mount is the standard “No Clamp" mount with the 63 degree Cant upgrade part for any model CAL or Super CAL Atlas Bipods. It includes two 10-32x3/8" hex flathead cap screws for attaching to compatible lever, spigot, M-LOK® or ARCA mounts.

See More Info below to ensure compatibility to your lever/clamp & firearm

Please review images to determine which Gen. 2 CAL mount you have. This is the only part we sell for end user installation.

Compass Bolt Head Feature: The Gen. 1 Compass Bolt had a hex feature. The Gen. 2 Compass Bolt does NOT have that feature. This upgrade will work on the Gen. 2 Compass Bolt. Before adding to cart, please indicate which compass bolt head feature you currently have (see last image to determine).
