Leupold STD 2-Piece Browning X-Bolt Aluminum Scope Bases - Black

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.
