The Atlas BT1517 Rail Mounting Fastener Set, part number BT1517 from B&T Industries, is the fixing kit for mounting B&T's 1913 rails. It contains two 10-32 T-nuts and two 10-32 × ¾ inch (19 mm) button head screws, and is compatible with both the BT15 and BT17 rails.
How It Compares
This is the fastener set, not a rail. The rails themselves are the Atlas BT15 3.35 inch radius-back Picatinny rail and the Atlas BT17 4 inch flat-back Picatinny rail. If you are replacing nuts for the AFAR rail kit rather than these rails, the correct part is the BT28-N AFAR rail nuts. Everything else is in our bipod accessories.
Ideal For
- Fitting a new BT15 or BT17 rail to a stock
- Replacing fixings lost during a stock refinish or rebuild
- Gunsmiths and stockers building rail mounting into a rifle
- Keeping a spare set with the rail
