Egw Swedish Mauser 3-Hole W/Hump 0 Moa

The EGW Swedish Mauser 3-Hole scope base with hump is a precision-machined mounting solution designed for classic Swedish Mauser rifles. Built from 6061 T6 aluminum, this base provides a solid, lightweight foundation for modern optics on a traditionally-configured rifle. The 0 MOA design sits flat on the rifle's receiver, making it ideal for shooters who want to mount a scope without adding elevation bias—your scope's adjustment range handles all the elevation tuning you need.

What sets this base apart is its Picatinny-compatible slot-and-rail design, which lets you adjust eye relief quickly and swap between scope rings without a trip back to the gunsmith. The cross-slots are gauged to MIL-STD 1913 specs (±0.002"), so rings sit securely whether you're using Picatinny or Weaver-pattern rings. The milled center channel reduces weight without sacrificing rigidity—a thoughtful touch if you're building a rifle you'll actually carry into the field.

Installation is straightforward: the base ships with socket head Torx screws and a wrench. EGW's recommendation is 20 inch-pounds of torque paired with a drop of blue Loctite to ensure the base stays put through recoil and handling. If you're restoring a Swedish Mauser or modernizing one for hunting or range work, this base gives you a clean, proven way to mount contemporary optics without permanent modification to the rifle's character.
