The Weaver 48096 Top Mount Base provides a rock-solid foundation for scope mounting on Winchester 70, 670, and 770 long action rifles. This precision-machined base eliminates the guesswork in scope installation while maintaining the low profile essential for proper cheek weld and sight alignment.
What Makes This Different
Unlike generic mounting solutions, the Weaver 48096 features rifle-specific machining that matches Winchester's receiver dimensions exactly. The base incorporates Weaver's proven cross-slot design that distributes recoil forces across multiple contact points rather than relying on simple screw retention. This engineering approach reduces scope shift under heavy recoil loads by up to 40% compared to standard bases.
Key Features
- Precision-fit design specifically engineered for Winchester 70/670/770 long action receivers
- Matte black finish resists corrosion and eliminates glare in field conditions
- Cross-slot configuration accepts standard Weaver-style rings and mounts
- Steel construction with hardened contact surfaces for maximum durability
- Low-profile design maintains proper scope height for comfortable shooting

Field testing demonstrates the 48096's ability to maintain zero through extended shooting sessions and temperature variations. The base performs consistently across hunting scenarios from mountain elk hunts to prairie varmint shooting. Competitive shooters report maintained accuracy through 500+ round count sessions without scope movement or base loosening.
