The EGW Mauser 98 Large Ring 20 MOA scope base is built for shooters who need precision mounting on classic large-ring Mauser actions with built-in elevation correction. Machined from 6061 T6 extruded aluminum, this base delivers the rigidity required for repeatable long-range accuracy while keeping weight minimal—the milled center channel trims unnecessary mass without compromising strength. If you're running a Mauser 98 and want to dial in serious distance without maxing out your scope's elevation turret, the 20 MOA (minute of angle) cant built into this base buys you extra vertical adjustment room downrange.
The Picatinny rail design accepts both Picatinny and Weaver scope rings, so you're not locked into one ring ecosystem. The cross-slots are gauged to MIL-STD 1913 specs to within ±.002 inches—tight tolerances that keep your rings and scope where you put them. Quick eye relief adjustments are simple thanks to the slot-and-rail spacing; swap your scope or rings and you're not starting over with a new base. This is the kind of foundational component that separates a sloppy build from one that groups tight.
Installation is straightforward. The base ships with socket head Torx screws and wrench, so you've got what you need to mount it. EGW recommends 20 inch-pounds of torque and a small drop of blue Loctite to lock everything in place and prevent shift under recoil. Whether you're building a long-range hunting rifle or a precision shooting platform, this base gives you the elevation correction and mounting flexibility to make the most of quality glass.
