Thanks. I'm in Charlotte so I guess my chances are pretty slim. I don't have any plans to get one...but it's nice to know that it's a possibility if I decide to.
However, I did see this document which seems to state that NC has a law against silencers. See page 25 item 10. It seems to state that a silencer or muffler of any type is considered a weapon of mass destruction. Does the NFA regulations get around state laws or am I missing something.
