Atlas BT43 Leveraged Rail
The BT43 Leveraged Rail is a BT20B and an American Defense ADM-170-S lever as a complete assembly.
The BT39 AIMB is mounted to the AI frame using your existing BT08 Stock Collar Fastener (this fastener is not included in the BT39, it is included with the BT08) being threaded to the lower AI butt pad bolt. The BT08 is then attached to the BT39 AIMB by means of the supplied 5/16-24 socket head cap screw.
Can be collected from our warehouse during regular business hours (M-F 9-5). Please allow 1 business day.
