Leupold steel Standard (STD) rings and bases are the most versatile mounting system available, designed to deliver exceptional performance and reliability. This specific model fits the Ruger 1022 and is an ideal choice for standard calibers up to .300 Win. Mag. STD rings come in five different heights and are precision-engineered to seamlessly match with both STD 1-piece and 2-piece bases. The front dovetail ring features a pivoting design that allows for lateral adjustment using the rear windage screws during bore sighting, ensuring optimal alignment.

The connection between your scope and firearm is crucial, which is why our mounts are built to be as rugged and dependable as the Leupold optics they secure. With a wide variety of mounting systems to choose from, you're sure to find the perfect match for your firearm and shooting style. Proudly made in the USA, Leupold mounts are guaranteed to withstand a lifetime of rigorous use, ensuring they will never let you down when it matters most.
