After being asked by precision 22 competitors for years, we are pleased to roll out a precision scope base for Ruger 10/22 receivers. This design, made from a single piece of T7075 aluminum and machined in house on our Haas VF4SS 4 axis machining center is designed to fit precisely, and strong enough that your rimfire will never budge it - all while providing the elevation you need for longer shots.Specifications and Features: Brand: Area 419 Ring & Mount Cant: 15 MOA Ring & Mount Type: Picatinny Style
