EGW Guns Scope Base Features The EGW Guns Scope Base is machined from solid 7075-T6 aircraft grade aluminum giving it the rigidity needed to hold zero under the recoil of long action Savage calibers. It is built specifically to work with any long action round back Savage receiver that has an ejection port fitting with #8-40 screws designed for that pattern. A matte black hardcoat finish resists wear and glare keeping the base from standing out against the rifle s factory finish. At just 2 ounces and 6.850 inches overall length the base adds minimal weight or bulk to the rifle while providing a full-length Picatinny mounting surface. The base accepts standard Picatinny or Weaver scope rings and is quick disconnect ring compatible giving the shooter the option to quickly remove and remount an optic without losing zero. Its ambidextrous design works equally well for right- and left-hand shooters and the 4.63 inch center spread matches the Savage round back receiver s mounting hole pattern. Installation hardware including #6-48 and #8-40 screws with a T-10 bit ships with the base for straightforward mounting. EGW recommends 20 inch-pounds of torque during installation giving Savage long action owners a reliable no-gunsmithing path to a one-piece scope mount.
