Appalachian Gun in Jasper has a 590 retrograde for 550 and a 590 A1 retrograde with ghost rings for around 825 . I bought a 590 A1 retrograde there myself. They are great people to deal with, very friendly. If you go there ask for Davenport or Josh. I looked on Gun Broker and the A1s were selling in the 1000 range. Also if you happen to go there, tell them that Gene sent you. Good luck. ...
