Leupold steel Quick-Release (QR) rings and bases provide a seamless solution for removing and replacing your optic on your firearm while maintaining zero accuracy (+/- 1/4 MOA). This specific ring model is designed to fit any riflescope with a 34mm maintube and pairs perfectly with our Quick-Release bases, making it particularly popular for muzzleloaders and large caliber rifles. The QR mounting system features a patented lever mechanism, meticulously machined with precision tolerances. This mechanism engages the steel base to the ring by pulling it down and forward, securely locking it into place. This intuitive system enables the use of multiple scopes on a single rifle, making it an excellent choice for hunters and shooters who travel by air and require easy scope removal. Our QR 1-piece and 2-piece bases accommodate all QR rings, delivering the convenience and field-proven accuracy you expect from a quality mount. The connection between your scope and firearm is critical, which is why our mounts are as rugged and dependable as the Leupold optics they support. 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 backed by a lifetime guarantee, Leupold mounts are built to withstand the test of time and performance.
