Weaver Mounts 48019 Top Mount Base #19 Black Aluminum for Winchester 1903

The Weaver Top Mount Base #19 is a precision-machined 1-piece aluminum scope base finished in gloss black, custom-fit to the Winchester 1903 bolt-action rifle. Built to Weaver's tight-tolerance standards, this top-mount base seats Weaver-style scope rings squarely so optics lock in and hold zero.

Manufactured in the USA from durable aluminum, the Base #19 offers maximum clamping strength without unnecessary weight. The detachable top-mount design bolts directly to the Winchester 1903 receiver. Pair it with your favorite Weaver-style rings to complete the optics-mounting system.
