really sorry to here about your problem. i have an edge in .223 and love it. i think i'd get some assorted sizes of shim material at your hardware store and shim it your self. don't tighten everything down too soon ,just use bore sighting to see when your cross hairs ar in the middle of your target when you have them centered in the scope tube. do it at just 50 yds or less. i think this will be a lot better than sending it in to the guys who worked on it before.
