Leupold steel Quick-Release (QR) rings and bases are designed to make it simple to remove and replace your optic while maintaining zero (+/- 1/4 MOA). This model, specifically designed for the Savage 10/110 Round Receiver, is a top choice for muzzleloaders and large-caliber rifles. The QR mounting system features a patented lever mechanism, machined to exact tolerances, that engages the steel base to the ring by pulling it down and forward, securely locking your optic into place. This easy-to-use system allows you to quickly swap between multiple scopes on one rifle, making it an excellent choice for hunters and shooters who frequently travel and need to remove their scope for transport. Leupold's QR 1-piece and 2-piece bases are compatible with all QR rings, offering field-proven accuracy and convenience. Built to be as rugged and reliable as the Leupold optics they secure, these mounts ensure a strong and dependable connection between your scope and firearm. Proudly made in the USA, Leupold mounts are guaranteed to last a lifetime, withstanding the toughest conditions. With a wide variety of mounting options available, you'll find the perfect match for your firearm and shooting style, ensuring consistent performance year after year.
