The Leupold Standard 2-Piece Steel Base for the Winchester 70 Reversible Rear (part no. 50021) fits the classic Model 70 with a two-piece rotary-dovetail mount built for repeatable alignment. Leupold machines the bases from steel and finishes them matte black, and the reversible rear element flexes to match different receiver contours. The rear ring’s windage adjustment screws preserve the scope’s internal windage for fine sighting, while shims handle gross elevation changes at 0 MOA baseline. Among scope bases for the Model 70, this Standard set is the fitted, proven choice.

Frequently Asked Questions

What does the reversible rear element do? It gives the rear base flexibility to match variations in receiver contour across Model 70 production, improving fit consistency.

Does this preserve my scope’s internal windage? Yes, the rear ring’s windage screws set lateral zero mechanically, so the scope’s own windage adjustment stays available for fine corrections.
