Weaver 48004 Top Mount Base 46S Silver - Browning/Beretta/Winchester

The Weaver 48004 Top Mount Base delivers rock-solid scope mounting for Browning, Beretta, and Winchester rifles with its precision-machined aluminum construction. This silver-finished base transforms standard hunting rifles into accurate long-range platforms by providing a stable foundation for optics.

What Makes This Different

Unlike generic mounting systems, the Weaver 48004 features rifle-specific engineering that matches the exact receiver dimensions of compatible firearms. The 46S configuration provides optimal scope positioning for proper eye relief and cheek weld. Precision CNC machining ensures consistent return-to-zero performance even after scope removal and reinstallation.

Key Features

• Precision-machined 6061-T6 aluminum construction for maximum strength-to-weight ratio
• Silver anodized finish resists corrosion and provides attractive appearance
• Rifle-specific design ensures perfect fit on Browning, Beretta, and Winchester receivers
• Standard Weaver/Picatinny rail compatibility accepts wide range of scope rings
• Low-profile design maintains clean rifle lines while maximizing scope clearance
• Precision-drilled and tapped mounting holes eliminate guesswork during installation
• Heat-treated aluminum maintains zero under heavy recoil conditions

Field testing demonstrates consistent accuracy retention across temperature extremes and extended shooting sessions. The rigid aluminum construction eliminates scope movement that can occur with flexible mounting systems. Professional gunsmiths recommend this base for hunting applications where reliability cannot be compromised, from African plains game to North American big game hunting.
