EGW Guns Heavy Duty Scope Base Features The EGW Guns Heavy Duty Scope Base is machined from solid extruded 7075-T6 aircraft grade aluminum with full-width Picatinny cross-slots gauged to MIL-STD 1913 specifications within 0.002 inches. This precision allows fast and simple changes to eye relief and gives the shooter broad flexibility in scope and ring choice. The base is drilled specifically to fit the factory scope mount holes on the Weatherby Mark V 9-lug bolt receiver so no drilling or tapping of the action is required. Its 0 MOA elevation keeps the base flat for standard hunting distances without compensating for bullet drop in the mount itself. A matte black finish resists glare in the field and matches the factory finish of most Weatherby rifles while the ambidextrous design works equally well for right- and left-hand shooters. At 7.064 inches overall length and just 2.5 ounces the base adds minimal bulk or weight to the rifle. The mount is quick disconnect ring compatible and ships with socket head screws and a wrench with EGW recommending 20 inch-pounds of torque and a drop of blue thread locker during installation. Entirely American made this EGW base gives Weatherby Mark V owners a reliable no-gunsmithing path to mounting a scope.
