Underclocked recommended the Warne QD rings to me. He was finally right about something (just kidding there buddy). The Warne QD rings are the best rings I have ever used. I have them on almost all my rifles. I have yet to have one not come back to true zero. Also I broke a ring (my fault I might add). I called Warne and their responce was, mail it to us with a letter and the had me a brand new set at my house in five days. Now that is customer service. The trick is you do not have to crank them down as hard as I was doing. Just thumb tight is all needed. They really do hold well and I recommend them to everyone that asks about rings.
