The EGW Winchester 70 Short Action scope base delivers a rock-solid one-piece Picatinny rail solution for your Winchester 70, engineered to mount directly to factory receiver holes with zero drilling or tapping required. Built from precision-machined 6061 T6 aluminum, this 20 MOA base combines lightweight construction with tactical-grade rigidity—ideal for hunters and shooters who demand repeatable accuracy on their bolt-action platform without gunsmithing hassle.
The full-width Picatinny slots conform to MIL-STD 1913 specs (±.002"), so you have total freedom choosing Picatinny or Weaver rings and adjusting eye relief to suit your optic and shooting position. The milled center channel reduces weight where it counts, and the one-piece design eliminates the precision losses that come with split or two-ring bases. Whether you're building a long-range rig or a close-quarters hunting setup, this base gives you the flexibility to dial in exactly what works for your gun.
Installation is straightforward: the base uses socket head Torx screws (wrench included) and EGW recommends 20 inch-pounds of torque plus a drop of blue Loctite to keep everything locked in place. No guesswork, no surprises—just a purpose-built mount that respects your Winchester 70's legacy while modernizing its optics capability.
