Leupold Standard 1-Piece bases fit most rifles. The forward part of the base accepts a dovetail ring, locking it solidly into position. The rear ring is secured by windage adjustment screws.

The Leupold steel standard bases and rings are the most versatile of any mounting system we offer. The rear ring is secured by windage adjustment screws, allowing the scope's internal adjustments to be reserved for precise sight-in. Additionally, shims can be used for gross elevation adjustment, reserving the scope's elevation adjustment for bullet drop compensation dial applications.
