EGW Guns Scope Base Features The EGW Scope Base for the Ruger 10/22 is precision machined from extruded 6061-T6 aluminum giving shooters a rigid accurate mounting platform for a rimfire scope. Picatinny slot-and-rail spacing allows fast and simple changes to eye relief and opens up a wide range of compatible scope rings rather than locking the shooter into a single ring style. The base is drilled specifically to the factory scope mount holes on the Ruger 10/22 receiver so it installs directly with no drilling or tapping required. A milled center channel keeps the lightweight tactical design from adding unnecessary bulk to the rifle. Full-width cross-slots are gauged to MIL-STD 1913 Picatinny specifications within plus or minus 0.002 inches ensuring rings seat securely and consistently. The matte black anodized finish on the 6061 T6 aluminum base resists wear from repeated mounting and dismounting of optics. EGW includes socket head screws and a wrench and recommends 20 inch-pounds of torque along with a drop of blue Loctite for a secure long-lasting installation. For Ruger 10/22 owners who want a dependable 0 MOA Picatinny base made in the USA the EGW Scope Base is a smart choice for sale at GrabAGun.
