I was really impressed with the look and feel of their Ultra-Light Tactical Rings. These rings are manufactured in Colorado out of 6061 T6 aluminum, and are intended to interface with a Mil-Std 1913 rail. They are hard black anodized, and come standard with a clever anti-cant level cap. These rings are available in 30mm, 34mm, 35mm and low, medium, and high. I think these rings would work well on any rifle build where weight saving is desirable.
