Quality bases are a must for any solid optics mount, and the Leupold BackCountry Cross-Slot 1-PC Rifle Base ensures that owners of Savage Model 10 and AXIS round-receiver, long-action rifles have a solid mounting point for their rings. These bases are machined from 7075-T6 aluminum and use a glare-reducing matte-black finish. The mounts can be had with either 0 or 20 MOA of built-in elevation. Mfg: Leupold
