Egw Mauser 98 Large Ring (3-Hole) Undrilled 0 Moa

The EGW Mauser 98 Large Ring scope base is a precision-engineered mounting solution built for classic and modern large-ring Mauser 98 actions. This undrilled, 0 MOA base gives you a clean slate to customize eye relief and scope selection on your build, with a Picatinny rail design that accepts either Picatinny or Weaver-pattern rings—flexibility that lets you match your optic and mounting hardware without compromise.

Machined from 6061 T6 extruded aluminum, the EGW Mauser 98 Large Ring base combines lightweight construction with rigid strength. The milled center channel reduces weight without sacrificing durability, while the full-width cross-slots are gauged to MIL-STD 1913 specifications (±.002") to ensure precise, repeatable ring seating. The three-hole mounting pattern is engineered specifically for large-ring Mauser actions, and the undrilled condition means you'll bed it exactly where you want it on your rifle.

Installation is straightforward: the base ships with socket head Torx screws and a wrench, and EGW recommends 20 inch-lbs of torque with a drop of blue loctite to secure everything permanently. The adjustable eye relief courtesy of the Picatinny rail design is a major advantage if you're building a precision rifle, hunting rig, or reconfiguring an existing setup—you can dial in the perfect viewing distance for your shooting style without swapping bases.
