Ruffs Precision Precision Scope Rings Features The Ruffs Precision Precision Scope Rings include a built-in co-linear bubble level visible to the shooter s non-dominant eye giving an instant reference to cant during the scope mounting process. This eliminates the need for multiple small levels and the balancing act that normally accompanies careful scope installation. An alignment lug ensures the cap and base stay properly aligned when the cap screws are installed which helps keep the ring torque even and the scope tube unmarred. These rings are machined from 6061-T6 aluminum for both the body and cap giving a strong lightweight structure suited to rifles that see hard field use. A 303 stainless steel cross bolt and nut sized at 1/2 inch clamp the rings securely to a Weaver-style base and recommended torque values of 18 in-lbs for cap screws and 45 in-lbs for the cross bolt are provided to prevent over-tightening. At medium height and 1.00 inch of ring clearance these rings are sized for a 35mm main tube scope with a larger objective bell. Proudly made in the USA the two-piece ring set weighs just 4.4 ounces keeping the overall rifle weight manageable.
