The Leupold Steel Standard Bases and Rings represent the pinnacle of versatility in mounting systems. Designed for a secure and precise fit, the rear ring is anchored with windage adjustment screws, ensuring that the scope's internal adjustments are preserved for fine-tuning sight-in. This thoughtful design also allows for the use of shims to achieve gross elevation adjustments, keeping the scope's elevation dial available for bullet drop compensation applications. Whether you're targeting precision or long-range accuracy, this system maximizes performance and ensures your scope stays finely calibrated for every shot.
