Leupold steel standard (STD) rings and bases stand out as the most versatile mounting system available. This particular model is tailored for a Savage 10/110-round receiver and is an excellent choice for standard calibers under 0.300 Win. Mag. The STD rings are available in five different heights, precision-engineered to perfectly complement STD 1-piece or 2-piece bases. The front dovetail ring is adjustable, allowing for lateral alignment through the rear windage screws during bore sighting. Additionally, shims can be employed to preserve the scope's elevation adjustment for BDC (bullet drop compensation) dial applications. The critical link between your scope and firearm is of paramount importance. This is why our mounts are as robust and dependable as the Leupold optics they secure. With an extensive range of mounting systems to choose from, you'll undoubtedly discover the ideal match for your firearm and shooting style. Crafted in the USA and backed by a lifetime of durability, Leupold mounts are a steadfast choice that will never disappoint.
