Description

The Weaver Standard Top Mount Aluminum Scope Base in silver (#46S) is a precision mounting solution designed for Winchester and compatible rifle platforms. This single-piece top-mount base serves as the foundation for any optics setup, enabling quick and secure attachment of scopes and sight systems without permanent firearm modification. Law enforcement and precision rifle shooters rely on top-mount bases when they need repeatable accuracy and the ability to transition between different optic configurations without zero loss.

Constructed from durable aluminum, the Weaver 48004 base features a silver anodized finish that resists corrosion and provides a clean, professional appearance on the rifle. The one-piece design eliminates the dimensional stacking issues inherent in two-piece systems, resulting in lower bore height and improved cheek weld geometry. The base is engineered to integrate seamlessly with Weaver-standard rings and mounts, utilizing proven dovetail geometry that has been the industry standard for decades. Its compact footprint (measuring 3.35 x 0.65 x 3.75 inches) ensures minimal rail obstruction while maintaining maximum load-bearing capacity for moderate to heavy optics.

This base is ideal for shooters building Winchester bolt-action rifles, lever-actions, or other platforms with compatible receiver dovetail dimensions. Installation requires no permanent modification to the firearm—the base seats directly into the receiver's top slots and secures via set screws, making removal and remounting straightforward. Tactical operators and hunters benefit from the lightweight construction (0.02 lbs) and the flexibility to swap optics while maintaining a consistent shooting platform. Verify your specific Winchester model's receiver profile before purchase to ensure proper fit and alignment.
