The Leupold steel standard bases and rings are the most versatile of any mounting system Leupold offers. 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.

Features:

• Matte black.
• Forged and machined steel construction.
• The forward part of the base accepts a dovetail ring, locking it solidly into position. The rear ring is secured by windage adjustment screws.
• 2-Piece bases offer maximum accessibility to the breech area of your rifle.
