Weaver 48421 Top Mount Base Savage 110 8-40 Screw Pattern Black

The Weaver 48421 Top Mount Base transforms Savage 110 rifles into precision platforms ready for modern optics. This machined steel base creates a rock-solid foundation for scope rings while maintaining the rifle's inherent accuracy potential.

What Makes This Different

Unlike generic bases that rely on soft metals or loose tolerances, the Weaver 48421 features precision-machined steel construction with exact dimensional specifications for the Savage 110 action. The matte black finish resists corrosion and glare while the traditional 8-40 screw pattern ensures compatibility with classic Weaver ring systems. Each base undergoes quality control testing to verify proper fit and alignment before packaging.

Key Features

• Precision-machined steel construction for maximum strength and durability
• Factory-specific design engineered for Savage 110 receiver dimensions
• Traditional 8-40 screw hole pattern accepts standard Weaver rings
• Matte black oxide finish prevents corrosion and eliminates reflective glare
• Low-profile design maintains clean rifle lines and reduces snag points
• Hardened steel screws included for secure, permanent installation
• Compatible with variable and fixed power scopes up to 56mm objective

Field performance depends on proper installation and quality rings, but the 48421 base provides the stable platform essential for consistent shot placement. Hunters appreciate the corrosion resistance during extended outdoor exposure, while target shooters rely on the dimensional accuracy for competition-grade precision. The steel construction handles recoil forces from magnum cartridges without shifting or loosening over time.
