EGW Springfield 03A3/03A4 Heavy Duty Steel Scope Bases.
Add the versatility of a one-piece Picatinny scope rail to your shotgun with no drilling or tapping. Precision machined from hardened steel with Picatinny slot-and-rail spacing that allows fast and simple changes to eye relief, plus great flexibility in scope choice. Drilled to fit the factory scope mount holes on the gun’s receiver. Accepts Picatinny or Weaver scope rings. Heavy Duty (HD) mounts are .100" lower than the Lightweight mounts to minimize weight and keep your optic closer to the barrel centerline for improved accuracy. Full-width cross-slots are gauged to MIL-STD 1913 specs to +/-.002". Machined from ultra-rigid 4140 carbon steel pre-hardened to Rc 35-35 before machining. Includes socket head Torx® screws and wrench. EGW recommends 20 inch lbs of torque and a drip of blue loctite.
