Leupold steel Quick-Release (QR) rings and bases provide a seamless solution for easily removing and replacing your optic on your firearm while maintaining zero (+/- 1/4 MOA). This specific ring model is designed to fit any riflescope with a 1 inches main tube and is intended for use with Leupold's Quick-Release bases. It is particularly popular among muzzleloader enthusiasts and owners of large caliber rifles. The QR mounting system features a patented lever mechanism, machined to precision tolerances, which engages the steel base to the ring by pulling it down and forward, securely locking it in place. This user-friendly system allows you to switch between multiple scopes on a single rifle, making it an excellent choice for hunters and shooters who travel by air and need to remove their scopes from their firearms. Our QR 1-piece and 2-piece bases are designed to accept all QR rings, providing you with the convenience and field-proven accuracy you expect from Leupold mounts. The connection between your scope and firearm is crucial for achieving optimal performance, 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 available, you're sure to find the perfect match for your firearm and shooting style. Proudly made in the USA and guaranteed to withstand a lifetime of rigorous use, Leupold mounts are designed to never let you down.
