The Atlas BT81 Lil' Brandi Sling Stud Adapter, part number BT81 from B&T Industries, is a sling stud to MIL-STD-1913 Picatinny rail adapter. Clamp it to a standard sling stud and any Picatinny-mount Atlas bipod goes straight on, with no drilling and no rail installation.
How It Compares
The BT81 is the no-gunsmithing route. Bolt-on rails such as the Atlas BT15 3.35 inch Picatinny rail and the Atlas BT17 4 inch Picatinny rail are more permanent and need matching stock holes. On an M-LOK handguard the equivalent is the Atlas BT73 M-LOK Picatinny rail. Bipods to go on it are in our Atlas bipod range and the wider UK rifle bipod range.
Ideal For
- Deer stalking rifles with a factory sling stud and no rail
- Wooden and synthetic sporter stocks the owner does not want drilled
- Night fox and vermin rifles fitted with a bipod occasionally
- Anyone who wants Picatinny mounting without gunsmithing

Frequently Asked Questions
What does the Atlas BT81 Lil' Brandi do?
The BT81 clamps onto a standard sling stud and provides a MIL-STD-1913 Picatinny rail, so a Picatinny-mount bipod can be fitted to a rifle that has no rail.
Does fitting the Atlas BT81 require drilling the stock?
No — the BT81 clamps to the existing sling stud, so no drilling or permanent rail installation is needed.
Which bipods will fit the Atlas BT81?
Any bipod with a standard MIL-STD-1913 Picatinny clamp will fit, including the two-screw Atlas models such as the BT10 and BT65 and the ADM lever models such as the BT46-LW17.
Should I choose the BT81 or a bolt-on rail?
Choose the BT81 when you want a reversible fitting on a stock with a sling stud, and choose a bolt-on rail such as the BT15 or BT17 when you want a permanent installation and your stock has matching holes.
