Weaver 48071 Top Mount Base - Browning/Sako Winter Hunter Black

The Weaver 48071 Top Mount Base delivers rock-solid scope mounting for Browning and Sako Winter Hunter rifles. This precision-machined base transforms your rifle's receiver into a stable platform for optics, ensuring consistent point of impact shot after shot. Built to withstand harsh hunting conditions and heavy recoil, this mount base maintains zero even under extreme temperature variations.

What Makes This Different

Unlike generic mounting solutions, the Weaver 48071 features rifle-specific machining that matches the exact contours of Browning and Sako Winter Hunter receivers. The base incorporates Weaver's proven cross-slot design with precise 0.206-inch slot spacing for universal ring compatibility. Each base undergoes CNC machining to maintain tolerances within 0.001 inches, eliminating the flex and movement common in stamped alternatives.
