Here's my experience with them. First I bought a maple stock for my T/C hawken. I had a fitting issue that I was able to resolved with a bit of wood work. But I did call them and told them and they said that they would definitely look into it so the next person wouldn't have an issue.
Second, a couple years ago I called to see if they had a .59 cal GM drop in barrel for my Renegade. The guy told me that they didn't have any more. BUT, about an hour later the same guy called me and told me that the owner had one he was taking to a gun show and asked me if I wanted it. Now that's customer service.
