EGW Guns Heavy Duty Picatinny Scope Base Features The EGW Guns Heavy Duty Scope Base is machined from ultra-rigid extruded 7075 T6 aluminum to replace a factory scope mount with a single Picatinny rail across the receiver. It is drilled to fit the existing factory mounting holes on a Howa 1500 or Weatherby Vanguard long action so installation requires no drilling or tapping of the receiver itself. Full-width cross-slots are gauged to MIL-STD 1913 specifications within two thousandths of an inch giving a shooter fast simple adjustments to eye relief and the flexibility to run nearly any Picatinny or Weaver ring and scope combination. A 0 MOA elevation keeps the base flat for standard hunting and range distances. At just .35 inch in height and 2.5 ounces the Heavy Duty profile sits .100 inch lower than EGW s Lightweight mounts minimizing added weight while keeping the optic closer to the bore centerline for improved accuracy. The matte black hardcoat anodized finish resists wear and corrosion for a durable long-lasting rail. Installation includes socket head Torx screws and a wrench with EGW recommending 20 inch pounds of torque and a drop of blue threadlocker for a secure mount. Ambidextrous and built for a 4.485 inch center spread this base is a straightforward upgrade for Howa 1500 and Weatherby Vanguard long action shooters.
