The Weaver Top Mount Base #12 (Weaver part no. 48012) is a black gloss aluminum alloy scope base machined specifically for the Remington 514/Winchester 71, giving the action a Weaver-pattern mounting surface for a set of rings. Weaver machines each base to tight tolerances so it seats on the receiver with a true, repeatable fit, then finishes it in black gloss to match most factory barreled actions. Built as a 1-piece top mount base, it bolts directly to the receiver using the rifle’s factory screw holes, no drilling or gunsmithing required. It’s a straightforward way to add optics to a Remington 514/Winchester 71 that didn’t ship drilled and tapped for a proprietary mount.
