EGW Guns Scope Base Features The EGW Guns Scope Base is machined from solid 7075 T6 aircraft grade aluminum a material chosen for its strength to weight ratio and its ability to hold zero under recoil. A matte black hardcoat finish protects the base from wear and corrosion while matching the factory finish of most rifles it is installed on. Built with a 0 MOA profile the base provides a flat true mounting surface without introducing any elevation bias into the optic s sight picture. The continuous Picatinny rail design is compatible with quick disconnect rings giving shooters the flexibility to remove and reinstall an optic without losing zero. At only 2.5 ounces the base adds minimal weight to the rifle while still providing a 5.094 inch overall mounting length and a 2.677 inch center spread for solid ring placement. Mounting hardware including number 6-48 by 1/4 inch screws and a T-10 bit is included along with a specified 20 inch pound torque rating for a proper secure installation. The base is purpose fit to the Bergara BMR action ensuring a precise bolt pattern match without any drilling or gunsmithing required. The EGW Guns Scope Base is made in the USA and available for sale at GrabAGun for Bergara BMR owners looking to mount a riflescope securely.
