I just got off the phone with them and they will be here in Vegas for the shot show. I was told that he always has on hand at least 50 of each setup. +1 for contacting them directly or come out for shot show if you really cant wait.
the reason, i went to us tactical, is that is what is says on the bottom of the McRee precision website. I didnt know I could contact Scott directly. I will do that.
