The Weaver Extended Multi-Slot Base (brand part number 99473) mounts a scope to a Browning AB3 short-action rifle while adding an extra inch of forward ring placement over a standard base. Weaver machines it from aircraft-grade 6061-T6 aluminum and finishes it with a Type-III hard coat anodized matte black coating, so it holds zero under recoil and resists wear from field use. The multi-slot layout accepts either Picatinny or Weaver-style rings, giving a shooter flexibility to run whatever mounting hardware they already own or prefer for eye relief. It’s a direct-fit, no-gunsmithing upgrade for a Browning AB3 owner who wants more ring position options than the factory base allows.
