EGW Guns Scope Base Features The EGW Guns Scope Base is machined from ultra-rigid extruded 6061-T6 aluminum giving it the strength needed to maintain zero through repeated scope mounting and field use. Drilled to align directly with the factory scope mount holes on the Winchester 70 short action receiver the base installs without any drilling or tapping of the rifle itself. Full width cross slots are gauged to MIL-STD 1913 Picatinny specifications within plus or minus .002 inches giving the shooter a tight repeatable fit with standard Picatinny or Weaver rings. The 0 MOA elevation keeps the scope s point of impact centered on the bore axis for shooters who do not require built-in cant. At 6.276 inches in overall length with a 3.259 inch center spread the base is sized to cover the full length of the Winchester 70 short action receiver for a solid stable mounting platform. The matte black anodized finish matches most factory Winchester finishes and resists the wear that comes with repeated field handling. Hex head mounting screws and a wrench are included to simplify installation and EGW recommends 20 inch pounds of torque with a drop of blue Loctite for a secure fit. For Winchester 70 short action owners seeking a reliable no-modification scope base EGW s Picatinny rail is a direct fit solution.
