Description

The BT20-B Atlas® Accuracy International Spigot Bottom Rail was originally designed to attach to the bottom of the BT19 AAIS. Progression of various mounting options prompted some end users to adapt their Atlas® Bipod while utilizing their existing quick detach lever on the “LW17” style of Atlas® Bipods and/or the 2-Screw mount style of Atlas® Bipods.

We found our BT20-B Bottom Rail to be the perfect solution to this request. By installing onto any clamp with matching center-to-center hole spacing of 1.100″, you are given a ready solution to adapt to your choice of attachment.
