Look up Weaver’s official base chart for select Browning, Winchester, and Beretta rifles and you’ll land on Application #46 — the exact base in this listing (Weaver part no. 48004). Weaver machines it from aluminum and finishes it in a silver matte that matches stainless and nickel-finished receivers. It bolts straight to the factory-drilled holes on these rifles, no gunsmithing required, and accepts standard Weaver-style rings. If you’re mounting a scope on a Browning, Winchester, or Beretta bolt rifle in this fit list, this is the correct base to start with.
