This supressor thing is ridiculous. Like I said contact AFTE directly in DC. Also, if you really want to get a fire started, write or e-mail your congressman and tell him you have had no response from this agency. I GUARANTEE you will get a response from both parties. A letter (certified) is best. Nothing light's a fire under some bureaucrat's posterior than a "Congressional". I know. I have seen the non-gun toting big-wigs running around like frightened children when they got a dreaded "Congressional".
