Leupold steel Quick-Release (QR) rings and bases are expertly designed to allow for the easy removal and replacement of your optic, all while maintaining zero (+/- 1/4 MOA). Specifically engineered for the Weatherby Mark-V, these mounts are a popular choice for muzzleloaders and large-caliber rifles. The QR mounting system features a patented lever mechanism, machined to precision tolerances, which engages the steel base by pulling it down and forward, securely locking your optic into place. This user-friendly system is ideal for hunters and shooters who use multiple scopes on one rifle or those who frequently travel and need to remove their scope for transport. The QR 1-piece and 2-piece bases accept all QR rings, providing field-proven accuracy and ease of use that Leupold is known for. The connection between your scope and firearm is critical, which is why Leupold's mounts are built to be as rugged and reliable as the optics they support. Made in the USA and guaranteed to withstand a lifetime of heavy use, Leupold mounts are designed for durability and performance in any shooting condition. With a wide variety of mounting systems available, you're sure to find the perfect match for your firearm and shooting style, ensuring consistent accuracy and dependability for years to come.
