Weaver 2-Piece (Pairs) Top Mount Aluminum Scope Base - Matte - Winchester 70 LA/SA

The Weaver 2-Piece Top Mount Aluminum Scope Base for Winchester 70 LA/SA is a precision mounting system designed for shooters who demand repeatable accuracy and reliable optic retention. This two-piece base configuration separates the front and rear mounting points, allowing for independent adjustment and alignment optimization, which is critical when installing quality optics on a rifle expected to perform in field conditions.

Engineered from aluminum and finished in matte black, the Weaver base resists corrosion and glare while maintaining a low profile that doesn't interfere with receiver-mounted accessories or backup iron sights. The two-piece design distributes clamping loads across separate mounting locations, reducing stress concentration at any single point and improving long-term zero retention through recoil cycles and temperature extremes.

Weaver's proven dovetail and Picatinny-compatible geometry ensures compatibility with Weaver and Picatinny scope rings, giving you flexibility in optic selection and replacement without base removal. Law enforcement and military armorers have trusted Weaver bases for decades, making them a standard-issue choice for Winchester 70 rifles in professional and competitive settings.
