EGW Guns Scope Base Features The EGW Guns Scope Base replaces the factory mounting system on a Browning A-Bolt long action with a single piece Picatinny rail giving shooters full width cross slots gauged to MIL-STD 1913 specifications within 0.002 inches. This precision eliminates the fitment issues that can plague aftermarket bases ensuring Picatinny or Weaver scope rings seat securely and consistently every time. A milled center channel reduces the overall mass of the mount keeping added weight to a minimum while in many cases preserving a clear line of sight to the factory iron sights. At a 0.4 inch height and 7.064 inch overall length with a 3.86 inch center spread the base is drilled specifically to match the Browning A-Bolt long action s factory scope mount holes for a drop in fit. Machined from ultra rigid 6061-T6 extruded aluminum the base is built to handle the recoil and vibration of hard use in the field without loosening or shifting over time. Hex head screws and a wrench are included for installation and EGW recommends 20 inch pounds of torque along with a drip of blue Loctite to keep everything secure. The matte black finish matches most factory and aftermarket finishes on a Browning A-Bolt rifle giving the installation a clean factory correct appearance.
