Weaver Mounts 99472 Extended Multi-Slot Base Black Aluminum Browning AB3 Long Action

The Weaver 99472 Extended Multi-Slot Base is a one-piece scope base purpose-built for the Browning AB3 Long Action rifle. Constructed from aircraft-grade 6061-T6 aluminum and finished in matte black Type III hard coat anodizing, this base delivers a lightweight, rigid mounting platform designed to hold up to repeated recoil.

The extended profile adds an additional inch of forward rail length compared to a standard AB3 base, giving shooters extra room to position long-objective scopes or fine-tune eye relief. Its multi-slot rail accepts both Weaver-style and Picatinny-style rings, while an integral recoil lug keeps the base locked down shot after shot.

Installation is straightforward. The base bolts directly to the factory mounting holes on the AB3 receiver with no bedding or gunsmithing required. This listing is for the base only; rings and optics are sold separately.
