EGW Guns Picatinny Scope Base Features The EGW Guns Picatinny Scope Base is machined from aluminum alloy giving owners of the Winchester Super X Pump and Impala Plus shotguns a durable lightweight mounting surface for optics. Picatinny slot-and-rail spacing allows fast simple changes to eye relief and offers far more flexibility in scope choice than a proprietary mounting system. The base is drilled to fit the factory scope mount holes on the receiver meaning no drilling or tapping is required for installation. Full-width cross-slots are gauged to MIL-STD 1913 specifications within plus or minus .002 inches ensuring Picatinny or Weaver rings seat securely and consistently. Lightweight Tactical mounts like this one feature a milled center channel for weight reduction keeping the base from adding unnecessary bulk to the shotgun. Hex head screws and a wrench are included with every base simplifying installation for owners adding a red dot or scope for turkey hunting slug shooting or home defense use. EGW recommends 20 inch pounds of torque along with a drip of blue Loctite to keep the base locked securely in place under recoil. Finished in a durable matte black this Picatinny base gives Winchester Super X Pump and Impala Plus owners a simple no-gunsmithing path to mounting an optic.
