Weaver Mounts 48004 46S Top Mount Base Silver Aluminum 1-Piece Browning/Beretta/Winchester

The Weaver Mounts 48004 Top Mount Base is a 1-piece Weaver-style scope base machined from durable, lightweight aluminum with a silver finish. Part of Weaver's 46S top mount series, this base is purpose-built to give you a rock-solid mounting platform for optics on Browning, Beretta, and Winchester receivers.

Weaver constructs each base to tight tolerances for a custom fit, giving rings the maximum strength to hold tight under heavy recoil. The classic Weaver cross-lock design accepts any detachable top mount Weaver ring, so you can pair this base with your preferred ring height and style (rings sold separately). The streamlined 1-piece top mount design keeps the optic positioned correctly for a repeatable cheek weld and consistent eye relief.

Lightweight aluminum construction keeps added weight to a minimum while providing the rigidity needed for reliable return to zero. Whether you are replacing a worn factory base or setting up a new optic, the Weaver 48004 offers an affordable, time-tested mounting solution for Browning, Beretta, and Winchester long guns.
