The EGW Mauser 98 Large Ring 0 MOA scope base is a precision-machined mounting solution built for shooters who demand solid, repeatable performance on classic Mauser 98 actions. If you're working with a vintage or modern large-ring Mauser and need a reliable way to mount modern optics, this aluminum base delivers the rigid foundation that separates a shooter from a hunting season full of reliability problems.
These bases are machined from 6061 T6 aluminum—a material choice that balances strength with lightweight design. The Picatinny rail design accepts both Picatinny and Weaver scope rings, giving you flexibility in ring selection without forcing you into a single product ecosystem. The slot-and-rail spacing allows you to shift your rings along the base to dial in eye relief for your particular scope and shooting style, so you get a custom fit rather than a one-size-fits-all compromise. Full-width cross-slots are gauged to MIL-STD 1913 spec within +/-.002 inches—tight tolerances that translate to zero shift between range visits and hunts.
Installation is straightforward: EGW includes socket head Torx screws and a wrench, so you're not hunting the hardware drawer. The manufacturer recommends 20 inch-lbs of torque and a small drop of blue loctite to lock everything in place permanently. The rigid extruded aluminum construction resists flex and vibration, keeping your zero stable through recoil and temperature swings—critical for hunters counting on their rifle when it matters most.
