Leupold steel Quick-Release (QR) rings and bases provide an effortless solution for removing and reattaching your optic while maintaining zero (+/- 1/4 MOA). This specific model is designed for the Remington 700 and is a popular choice for muzzle loaders and large caliber rifles. The QR mounting system features a patented lever mechanism, precision-machined to create a secure connection between the steel base and the ring. By pulling the lever down and forward, the system locks firmly into place, allowing for quick transitions between multiple scopes on one rifle. This functionality is particularly advantageous for hunters and shooters who travel by air and prefer the convenience of detaching their scope for transport. Our QR 1-piece and 2-piece bases are compatible with all QR rings, providing the convenience and field-proven accuracy you expect from Leupold mounts. The connection between your scope and firearm is crucial, which is why our mounts are engineered to be as rugged and dependable as the 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, Leupold mounts are designed to withstand a lifetime of rigorous use, ensuring they will never let you down when it matters most. Enhance your optics setup with Leupold QR rings and bases for exceptional reliability and versatility.
