EGW Guns Scope Base Features The EGW Scope Base is precision machined with full-width cross-slots gauged to MIL-STD 1913 specifications to within plus or minus .002 inches ensuring a consistent reliable fit for Picatinny and Weaver rings alike. Its heavy duty profile sits .100 inches lower than EGW s lightweight mounts keeping the optic closer to the barrel s centerline for improved accuracy on the Howa 1500 and Weatherby Vanguard short action platforms. The slot-and-rail spacing allows fast simple changes to eye relief and ring position giving shooters flexibility in scope selection and placement. Because it is drilled to match the factory scope mount holes on the receiver installation does not require drilling or tapping the action. Machined from solid 7075-T6 aircraft grade aluminum the base is built to handle recoil and mounting torque without flexing or loosening over time. It ships with socket head Torx screws and a wrench and EGW recommends 20 inch pounds of torque along with a drip of blue threadlocker for a secure long-term mount. The ambidextrous design works equally well for right- and left-handed shooters setting up their rifle. Finished in Black and weighing only 2.5 ounces the EGW Scope Base is for sale at GrabAGun for shooters wanting a durable American-made one-piece rail.
