Leupold steel Standard (STD) rings and bases are the most versatile mounting system in our line-up, offering exceptional performance for a wide range of firearms. This specific model is designed to fit a Browning A-Bolt WSSM and is ideal for standard calibers up to and including .300 Win. Mag. The STD rings come in five different heights, allowing you to select the perfect fit for your rifle. They are precision-engineered to pair seamlessly with Leupold's STD 1-Piece or 2-piece bases. One standout feature is the front dovetail ring, which pivots to allow lateral adjustment using rear windage screws, making bore sighting quick and easy. Additionally, shims can be used, reserving the scope's elevation adjustment for Bullet Drop Compensation (BDC) dial applications, ensuring precise adjustments for long-range shooting. Leupold's mounts are built to withstand the toughest conditions, offering reliability that matches the ruggedness of the optics they secure. Whether you are a hunter, target shooter or tactical enthusiast, Leupold mounts provide the durability and accuracy you expect. With a broad selection of mounting systems available, you'll find the perfect solution to meet your firearm and shooting style needs. Proudly made in the USA and guaranteed to hold up under years of use, Leupold mounts are a reliable choice that will never let you down.
