Weaver Mounts 48053 Top Mount Base #53 Black Aluminum Winchester 88/100

The Weaver Mounts 48053 Top Mount Base #53 is a 1-piece scope base machined from aluminum and finished in gloss black, purpose-built for the classic Winchester Model 88 and Winchester Model 100 rifles (also cross-fits select Sako models). It provides a solid, factory-pattern mounting platform for Weaver-style rings, allowing you to securely attach a scope or red dot to your rifle.

Each Weaver #53 base is machined to tight tolerances for a precise, custom fit on the receiver, delivering the maximum strength needed to keep your rings locked down shot after shot. The signature Weaver cross-lock design and included mounting screws make installation straightforward, while the gloss black finish blends cleanly with the factory bluing found on these vintage Winchester rifles.

This is a receiver-mounted, top-mount 1-piece base in the Weaver mounting pattern. Rings are sold separately, letting you choose the ring height and style that best match your optic and intended shooting application. The Weaver #53 is a direct, no-modification drop-on base for factory-drilled and tapped Model 88 and Model 100 receivers.
