The Leupold steel STD 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.
This 30mm diameter all aluminum scope ring works with Weaver style and Picatinny bases. Four screws per ring hold the top cap securely in place preventing movement of the scope in the rings. The steel cross bolt withstands Magnum Recoil. Wrap-around design manufactured from Aircraft aluminum. Maximum scope retention and twice the clamping area. Exceptional clamping strength.
The characteristic that distinguishes the Quick Release™ system from the Dual Dovetail™ and STD systems is the ability to remove the scope from the rifle and reattach it without the loss of zero (within ½-MOA). This system boasts machined steel construction and supremely close machining tolerances.
