Browning 12389 T-Bolt Two-Piece Scope Base Matte Black

The Browning 12389 is a two-piece scope base purpose-built for the Browning T-Bolt rimfire rifle. Machined from solid steel and finished in a low-glare matte black, this base set delivers a secure, repeatable mounting platform that keeps your optic sitting low over the bore for a clean sight picture and consistent cheek weld.

Browning's signature double recoil shoulder design locks each base positively into the T-Bolt's receiver to absorb the sharp impulse of magnum rimfire cartridges without shifting point of impact. The two-piece layout mounts directly to the receiver using the factory screw holes, with no bedding, drilling, or gunsmithing required. The split design also lets you space your rings to fit virtually any scope tube diameter or objective bell.

This base is engineered exclusively for Browning T-Bolt rifles chambered in .22 LR and .17 HMR. Scope rings are not included and must be purchased separately to match your optic's tube diameter.
