The BT49 - 2.05" 1913 Adjustable Picatinny Rail has a center-to-center spacing of 1.2 - 1.6" with a 1.00" radius back. Two machine screws can be used, but are not included (see BT1517) to attach this rail to the forearm of standard rifle stocks.

The BT49 can also be attached to a horizontal surface on the Butt section to attach our Precision Rail Monopods (BT12, BT13, BT31).
