Tier One 11mm DOVETAIL scope mounts are precision made on 5 axis CNC machinery. They are the perfect mount for serious enthusiasts because they are lightweight, extremely accurate, and built tough.The key to making an accurate mount is to manufacture the product in as few operations as possible, on very high quality machinery. By investing in cutting edge, 5 Axis CNC machines and advanced technology we have been able to cut the number of operations required from eight to two. This means there is no accuracy loss due to re-setting for different operations and we can complete each set of rings from the same solid billet.If you were to stack your tolerances across each of your accessories and critical parts you may find that you actually have a very loose setup, and that leads to inaccuracy and poor performance.With Tier One scope rings you can be assured that you have the very tightest tolerances possible, and a sturdy platform for repeatable performance. These rings are a perfectly m...
