Weaver Extended 1-Piece Base for Winchester 70 SA - 6061-T6 Aluminum

Overview

The Weaver Extended 1-Piece Base is crafted for Winchester Model 70 Short Action rifles produced between 1984 and 2008. This single-piece, extended base rethinks mounting space, offering an extra inch of forward length to accommodate a broader choice of scopes and rings while preserving a low, clean silhouette.

Durable build and finish

Made from 6061-T6 aluminum, the base balances strength and lightness for field use. The matte Type III hard coat anodize provides a rugged, low-reflection surface that resists scratches and weathering during hunts or range sessions.

Mounting compatibility

The base is designed to work with both Picatinny and Weaver-style rings, giving you flexible hardware options. The no-slip, non-strip Torx screws help maintain alignment and reduce the risk of movement under recoil.
