Thanks for the replies.
I'm an lawyer, not directly involved with firearms laws, but have read them in this state.
I'd have to try to review the Federal case law (if any is out there) with regard to "posession with intent to violate NFA" situations. I imagine you could be in this situation if you had say an AK parts kit with all of the FA parts and bought a receiver flat. Theroetically you could assemble it into a NFA weapon. The posession of the short barrel alone *could* be evidence of intent to assemble an NFA weapon in violation of US law. I guess the bottom line for me is I'd hate to be the test case ...an attorney has a column in every Small Arms Review mag, I should get in touch with him.
PS yes, even though I'm a lawyer I'd want to talk to a specialist in this area, too much stuff I don't know in this area of law...
Thanks.
