The EGW Ruger M-77 Long Action scope base gives you a modern Picatinny rail mounting solution for a classic rifle. Built from 6061 T6 aluminum and machined to MIL-STD 1913 specifications, this one-piece base replaces your factory M-77 mount without requiring additional drilling and tapping—it uses the rifle's existing receiver holes. If you're upgrading from iron sights or swapping to a different scope, this rail gives you flexibility in eye relief adjustment and the ability to use any Picatinny or Weaver scope rings you choose.
The 20 MOA built-in inclination is a popular choice for long-range shooters who want to maximize their scope's vertical adjustment range at distance without having to dial up excessively. The precision-machined cross-slots meet strict tolerances (±.002"), so your rings stay put once they're torqued down. The extruded aluminum construction keeps weight minimal—important on a rifle you're actually going to carry—while maintaining the rigidity you need for reliable scope mounting.
Installation is straightforward: the base drops onto the M-77's receiver using its factory hole pattern, comes with socket head Torx screws and the wrench to install them, and EGW recommends 20 inch-pounds of torque and a drop of blue Loctite to secure everything. Whether you're building a hunting rifle, a long-range precision setup, or just modernizing a rifle you've owned for years, this mount is a practical way to get a quality Picatinny platform on an M-77 without gunsmithing.
