BT6569ML / BT6569ML-NC: Atlas CAL Upgrade Mount


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.

Variation differences and compatibility detailed in description below.

SKU: N/A Categories: , Product ID: 1386


Each variation is machined from 6061-T6 aluminum that is hard anodized black with Mil-Spec Type III, Class 2 finish. Available in black only.

The BT6569ML (2-Screw Clamp) Mount is the standard two-screw mount with the 63 degree Cant upgrade part for any model of CAL or Super CAL Atlas Bipod. It mounts directly to any 1913 style Picatinny rail via a low profile two screw clamp assembly.

The BT6569ML-NC (No Clamp) Mount is the standard “No Clamp” mount with the 63 degree Cant upgrade part for any model CAL or Super CAL Atlas Bipods. It has a two hole pattern of 1.100” with the holes being 10/32 threads. It requires any 17S size ”Lever Mount” to such as the ADM-170-S, ARMS 17S, TRAMP from Badger Ordnance, LT271 or most ARCA dovetail mounts with the same hole pattern. It is NOT compatible with the Magpul® QR Rail Grabber (MAG1196). The BT6569ML-NC will also mount directly to our BT19 (AI) Spigot and BT70 M-LOK® Adapter. Includes two 10-32 x 3/8″ hex flathead cap screws 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 (see last image to determine).

INSTRUCTIONS: Replacing the Mount on any CAL or Super CAL Atlas Bipod
