Picatinny Rails

If your rifle does not have a rail where you need to mount an Atlas, these Picatinny rails add one. B&T offers short forend rail sections, an adjustable rail, and the BT81 sling-stud adapter, so you can give almost any rifle a clean Picatinny mounting point for a bipod or monopod. This page helps you pick the right rail for your forend, your stud, or your length needs. Everything is American-made and backed by a lifetime warranty.

New to rails? A Picatinny rail (the MIL-STD-1913 slotted standard) is the mounting platform that gives a bipod, monopod, or accessory a place to clamp onto your rifle. For the full standard-by-standard breakdown of what a Picatinny rail is and how it compares to M-LOK and Weaver, see our explainer. Below, pick the B&T rail, mount, or accessory that fits your setup.
