EGW Guns Scope Base Features The EGW Guns Scope Base is machined from solid 6061 T6 aircraft grade aluminum into a one-piece Picatinny rail giving the Howa 1500 Mini Action a rigid single-unit mounting platform rather than a split two-piece base. Built in with 20 MOA of elevation the base shifts the scope s usable adjustment range upward which matters most to shooters stretching a rifle s effective range well past typical hunting distances. The matte black hardcoat finish protects the aluminum from scratches and corrosion while blending cleanly with most factory metal finishes. At just 2.5 oz the base adds negligible weight to the rifle while providing a full 5.882 of mounting length and a 3.155 center spread. This base is compatible with both Picatinny and Weaver scope rings including quick-disconnect ring systems giving shooters flexibility in choosing their preferred mounting hardware. The ambidextrous design works equally well for right- and left-handed shooters setting up optics on their Howa 1500 Mini Action. Mounting hardware including screws and a T-10 bit ships with the base and EGW specifies a 20 in/lbs torque spec for proper installation. Made in the USA this scope base gives Howa 1500 Mini Action owners a durable precision-machined mounting solution built to EGW s established quality standard.
