Performance & Practical Use

This two-piece base forms the crucial link between your rifle and optic. The precision-machined steel construction delivers a solid mounting platform that helps maintain alignment over repeated shooting sessions. The separate base pieces also make it easier to place scope rings exactly where you need them without sacrificing access to the rifle’s breech or controls.

During installation, the pivoting front dovetail allows you to fine-tune the lateral placement of your rings with the rear windage screws, helping streamline bore-sighting and initial setup. Using optional shims under the front ring can reserve your scope’s internal elevation adjustments for fine tuning, especially when using long-range or high-BDC optics.

Made with Leupold’s reputation for ruggedness in mind, this base is suitable for everyday hunting, range use, and field shooting where durability and repeatable performance matter.

Best Suited For

✔ Hunters and shooters mounting optics on Mauser 98 or similar large-ring rifles
✔ Users who want a two-piece base for flexible ring placement
✔ Shooters pairing with Leupold STD rings for adjustable ring height options
✔ Optic setups where windage adjustment and bore-sighting access are helpful
