Leupold 57310 Standard Scope Base Winchester 70 WSSM Matte Black

The Leupold 57310 Standard Base transforms Winchester Model 70 WSSM rifles into precision platforms ready for serious optics. This two-piece scope mounting system eliminates the guesswork and potential accuracy issues that come with inferior bases, providing the rock-solid foundation your expensive glass deserves.

What Makes This Different

Leupold's machining tolerances exceed industry standards, with each base precision-cut to match Winchester's receiver dimensions exactly. Unlike generic alternatives that rely on one-size-fits-all approaches, this base is engineered specifically for the WSSM action's unique geometry. The matte black finish resists glare and corrosion while maintaining a professional appearance that won't compromise your position in the field.
