Weaver Standard Top Mount Aluminum Scope Base - Gloss Black - #47 - REAR Sears 53

The Weaver Standard Top Mount Aluminum Scope Base in gloss black finish is a single-piece optical mounting platform engineered for rifles requiring a solid, repeatable connection between the firearm's receiver and optics. The #47 rear base configuration is designed for Sears 53 receivers, making it an essential component for operators and enthusiasts looking to mount precision optics on heritage or legacy rifle platforms.

This Weaver base employs aluminum construction to balance weight and durability while maintaining the mechanical rigidity required for maintaining zero under recoil. The gloss black finish provides moderate corrosion resistance appropriate for standard indoor range and field use. As a rear-position base, this component pairs with a front base to establish the full mounting plane for Weaver-pattern rings and optics. The base is supplied with precision-cut fastening hardware sized specifically for secure installation into the receiver's threaded holes—no gunsmithing modifications required. The one-piece design eliminates base-to-base alignment issues that can complicate two-piece setups, simplifying the scope mounting process and reducing potential points of failure.

This rear base suits shooters working with vintage rifles, legacy firearms in collections, or specialized builds using Sears 53 receiver dimensions. Competitive shooters, hunters, and rifle sport competitors who require reliable optics platforms for precision work will find this base delivers the straightforward mounting solution Weaver bases are known for. Whether setting up a long-range hunting rifle or restoring a classic platform to modern capability, Weaver top-mount bases remain the industry standard for non-tactical applications where quick-detach systems are not essential.
