Accu-Shot Atlas Picatinny Rail Adapors
The BT15 3.35" Picatinny Rail will accommodate hole patterns with a center to center spacing of 1.76 to 2.78" with a relieved base to accommodate curved surfaces. The BT17 - 4" 1913 Rail will accommodate hole patterns with a center to center spacing of 2.2 to 3.5" with a FLAT base to accommodate flat surfaces. A standard sling stud can be used as one fastener or two Button head machine screws can be used (not included, see BT1517) to attach this rail to the forearm of standard rifle stocks. The BT15 or BT17 can also be attached to a horizontal surface on the Butt section to attach our BR12 or BT13 Precision Rail Monopods. Both rails have a built in flush cup bushing for QD sling swivels.
