BT6569ML / BT6569ML-NC: Atlas CAL Upgrade Mount

New product

The BT6569ML and BT6569ML-NC are current production CAL mounts that provide 45 degrees of Cant. All Gen. 2 CALs shipped from B&T Industries through August 2019 had 30 degrees of Cant. While fully functional, additional Cant is considered an upgrade (see illustration to determine which mount you have). This additional 15 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 45 degree Cant upgrade part for any CAL or SCAL Atlas Bipod.

The BT6569ML-NC Mount is the standard “No Clamp" mount with the 45 degree Cant upgrade part for any CAL or SCAL Atlas Bipods. Two 10-32x3/8" hex flathead cap screws are included for attaching to compatible lever, spigot, M-LOK® or ARCA mounts.

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.
