The Weaver Extended Multi-Slot Base (Weaver part no. 99472) is built specifically for the Browning AB3 long action, giving shooters a Picatinny/Weaver-compatible foundation with a full forward length of extra rail for mounting scopes, night vision, or other rail accessories. Machined from 6061-T6 aluminum with an integral recoil lug, this base resists shifting under recoil and includes no-slip, no-strip Torx mounting screws for a secure, repeatable install. The tactical multi-slot design has no built-in elevation bias, giving shooters full control over how they configure their optic setup, and the Type III hard coat anodized finish holds up to field wear.
