Weaver Mounts 48046 Top Mount Base 46 1-Piece Aluminum Black - Browning/Savage/Marlin

The Weaver Top Mount Base #46 is a rugged 1-piece scope base purpose-built to fit Browning, Savage, and Marlin rifles. Each base is machined to tight tolerances for a custom fit, and the durable aluminum construction with a classic black finish gives rings the strength they need to hold zero under hard use in the field.

Designed in the time-tested Weaver pattern, the 48046 top mount base bolts directly to the receiver and accepts any standard Weaver-style scope ring (rings sold separately). The single-piece design eliminates alignment concerns between separate front and rear bases, giving you a rock-solid, repeatable mounting platform for your optic. This base is purpose-built for the specific Browning, Savage, and Marlin rifles listed in the Weaver #46 fit table, so installation is straightforward and the fit is dialed in from the factory.

Whether you are replacing a worn factory base, swapping an old optic setup, or mounting a brand new scope, the Weaver 48046 Top Mount Base delivers the fit, strength, and value that have made Weaver a trusted name in scope mounting for generations.
