After being asked by precision 22 competitors for years, Area 419 are pleased to roll out a precision scope base for Ruger 10/22 recievers. This design, made from a single piece of T7075 aluminum and machined in house on Area 419's 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. Bases will come Type III black hardcoat anodized and will come with the necessary wrench for torquing the clamp screws. Recommended torque spec: 15 in/lb The rail comes in a 30MOA cant as it is meant for guys pushing their 22LRs out to 300+ yards or usin Mfg: Area 419
