Just to set the record straight on a few things:
A NJ resident can purchase a longarm out of state just like everyone else, that's a Federal law. Only NJ specific requirement is that the buyer have a valid FOID and sign a Certificate of Eligibility.
That being said the gun and magazines must adhere to NJ law and that is where the issue is, specifically with a WASR and/or an AK47. The NJ AWB, there is no pre_ban grandfathering in NJ, prohibits "AK47 type" firearms. Its the vagueness of that language that is troublesome, what is AK47 type?
BTW...mags are limited to 15 rounds, not 10.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)
"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
