BT81: Lil’ Brandi – Sling Stud to Picatinny Rail Adapter

Looking for a no-fuss way to mount a 1913 Picatinny rail onto a traditional rifle stock—without drilling, gunsmithing, or permanent modification? The BT81 Lil’ Brandi has you covered. Proudly crafted from 7075‑T6 aluminum and finished with Mil‑Spec Type III Class 2 hard coat, this rail adapter simply clamps onto your existing sling stud. It comes with a cross-pin, set-screw, and hex wrench for quick, secure installation.
Featuring three functional Picatinny rail slots, it supports attaching Atlas® Bipods or sling mounts without any hassle. The rail achieves rock-solid stability as the internal angled slot allows the cross-pin to wedge the unit firmly against the stock when the set screw is tightened. This elegant, patent-pending design ensures a snug fit—no disassembly required—while the angled wings with rubber pads protect the stock’s finish. Designed for curved stocks (not flat stocks), the BT81 measures 1.95″ × 1.50″ × 0.663″ and weighs just 0.89 ounces.
