These rings are some what of a new product to the shooting world. I saw them at the 2011 Shot Show, and thought they were worth showing to all of you. They are made from the strongest aircraft aluminum available, and are engineered to provide the most even clamping pressure with minimal torque on the low profile screws. They are light weight and slim in profile. I used them for the first time on a rifle I built for my self recently and couldn't be happier. I will post pics of the rifle in the bolt rifle section of the rifle which I installed them on. They normally come black anodized in any size that scopes are made, but I asked for them in the white so that I could polish them for my application. If any one wants more info look them up by company name. American Rifle Company.
