I highly suggest you talk to the "home office." Call the ATF-NFA branch, Technologies division. Let me know what they tell you. If you want to know about the NFA rules, call the NFA. You're local branch office isn't the correct "source."
If you will take a letter as "proof" perhaps a conversation with the folks who WRITE the letters will suffice?
ATF NFA branch: 304-616-4500
