Getting a bipod onto your rifle starts with knowing your mount. These guides explain the four systems you will run into, Picatinny, M-LOK, ARCA, and sling studs, show which Atlas adapter bridges them, and walk through installing a rail so any rifle can take a bipod.

Frequently Asked Questions
How do I know if my rifle is M-LOK or Picatinny?
Look at the underside of your fore-end. M-LOK is separate oblong slots cut into a smooth handguard; Picatinny is a continuous ridged rail. Small slots mean M-LOK; an unbroken ridged rail means Picatinny. The mounting guides here show each side by side.
Which Picatinny to M-LOK adapter do I need?
It depends on your goal. To mount an Atlas bipod on an M-LOK handguard, use the BT70 Atlas M-LOK adapter. To add a Picatinny rail section or a sling point, other B&T adapters fit. The adapter guide maps each goal to the right part.
How do I mount a bipod if my rifle only has sling studs?
Use the BT81 Lil' Brandi adapter. It threads onto a front sling stud and converts it to a short Picatinny rail, so a standard Atlas bipod can clamp on, with no gunsmithing. This is the common path for hunting rifles.
