I know a lot of us piss, and moan about the ATF in general. My communication with them has been Fantastic! I even received a return call on the weekend when I was dealing with the Cascade fiasco. I just got a job opportunity to work in Lawton, OK, and (I think they expedited my suppressor approval) to make it happen. I know ATF should be a convenience store, but if you talk to them in a professional manner they will respond in kind.
