These Talley Manufacturing Ruger American Scope Mounts provide a singular and straightforward one-piece scope ring and base solution for the Ruger American rifle. The risk of a "out of alignment" interface or "loose connection" between the ring and base of conventional two-piece designs is eliminated by this streamlined mounting solution. Overall, this is lower in weight and offers more strength and longevity than competing steel rings and bases. This sturdy scope mounting platform doesn't need to be lapped and is ready to use right out of the box thanks to its complete CNC machining from lightweight aircraft-grade aluminium to the closest tolerances in the industry.
