Area 419 Scope Base Features The Area 419 Scope Base was developed after years of requests from precision .22 competitors looking for a dedicated mounting solution for the Ruger 10/22 platform. Machined from a single piece of T7075 aluminum the base is cut in house on Area 419 s own Haas VF4SS 4 axis machining center for tight tolerances and a precise fit to the receiver. The 30 MOA of elevation built into the MIL-STD 1913 Picatinny rail gives shooters the additional adjustment needed to reach out to longer rimfire distances without running out of turret travel. At 9.25 long and just 0.17 lb the base adds minimal weight while providing a full length mounting platform for rings or a cantilever mount. The Area 419 Scope Base ships finished in Type III black hardcoat anodizing for a durable corrosion resistant surface that stands up to repeated handling and range use. It includes the necessary wrench for properly torquing the clamp screws so the base can be installed and secured without hunting for the right tool. Built strong enough that a rimfire action will never shift it under recoil the base is designed to keep a mounted optic returning to zero. The Area 419 Scope Base for Ruger 10/22 is a purpose built upgrade for shooters serious about rimfire precision.
