The Weaver Standard Top Mount Aluminum Scope Base in silver (Model 48002) is a precision one-piece mounting solution engineered for rifles requiring a direct-to-receiver optics platform. This aluminum base provides a secure, snug-fitting interface between your rifle's receiver and Weaver-compatible scope rings, enabling reliable sight picture stability through extended field use and tactical training cycles.
The single-piece aluminum construction eliminates the shifting and tolerance stack-up inherent to two-piece base systems. Its compact 3.35-inch length and minimal profile—0.6 inches in height—minimize additional weight (0.03 lbs) while maintaining the rigidity necessary to prevent zero shift during firing. The silver anodized finish provides corrosion resistance in typical field conditions. Installation requires no receiver modification on compatible platforms, allowing for tool-free mounting and removal when switching between rifles or transitioning to alternative sight systems.
This base is engineered for rimfire and centerfire rifles including Anschutz, Churchill, Cooey, Knight, Sako, Savage, and Tikka platforms—making it a standard choice for precision shooters, small-bore competition shooters, and hunters who rely on bolt-action rifles. The top-mount configuration positions optics directly above the barrel centerline, improving sight radius compared to side-mount alternatives and enabling more ergonomic cheek weld geometry on rifles with traditional stock architecture.
Weaver bases are an industry standard in the precision rifle world due to their consistent dovetail dimensions and widespread ring availability. This top-mount option complements Weaver's full line of one- and two-piece bases, giving operators flexibility in mounting height and configuration based on their specific rifle ergonomics and sight picture requirements.
