EGW Guns Scope Base Features The EGW Guns Scope Base is precision machined from domestic 6061-T6 extruded aluminum giving it the rigidity needed to hold zero through repeated scope changes and range sessions. The base is designed specifically for the Ruger 10/22 and 10/22 Takedown platforms aligning directly with the factory scope mount holes already present on the receiver. Full width cross slots meet MIL-STD 1913 Picatinny specifications allowing the shooter to use standard Picatinny or Weaver rings and adjust eye relief by sliding the rings forward or backward along the rail. This 0 MOA design keeps the scope centered on the bore line without introducing any additional cant. Finished in a silver matte anodized coating the base is designed to complement the factory finish found on many Ruger 10/22 rifles rather than clash with it. At 4.645 inches in overall length with a 2.57 inch center spread the base is sized to fit cleanly across the compact 10/22 receiver without overhanging. Hex head mounting screws and a wrench are included simplifying installation without the need for additional tools. For 10/22 and 10/22 Takedown owners who want a clean correctly finished scope mounting solution the EGW Scope Base offers a direct well matched fit.
