The EGW Mossberg 500, 590, 835, 930, 935 post-1997 scope base lets you add an optic to your shotgun without gunsmithing. This one-piece Picatinny rail mounts directly to your receiver using the factory scope mount holes—no drilling, no tapping, no trips to the gunsmith. Whether you're setting up a deer gun, a tactical platform, or a long-range slug shooter, a solid scope base is where accuracy starts.
Built from 7075 T6 extruded aluminum and machined to MIL-STD 1913 Picatinny specs, this base is rigid enough to hold zero through hard use. The heavy-duty profile sits 0.100" lower than standard mounts, keeping your optic closer to the barrel centerline for better sight picture and less height-over-bore. Full-width cross-slots are gauged to +/−0.002" for fast, repeatable ring adjustments and simple eye relief changes. Works with any Picatinny or Weaver scope rings, giving you flexibility in your optic choice.
Installation is straightforward: the base drops onto your Mossberg's receiver, aligns with the existing holes, and you're ready to mount rings and glass. EGW includes socket head Torx screws and a wrench; they recommend 20 inch-pounds of torque and a drop of blue Loctite for a permanent, vibration-proof fit. This is the kind of foundation that turns a shotgun into a real precision tool.
