Is it legal to own FAL-FN-type rifles in NJ, assuming they don't have too many evil features?

Sorry to ask such a simple question, but I have to know before making a bid.

Thanks all.

Check out this site! Also keep in mind the 15 round mag rule.  Preban or not, a magazine capable of holding more than 15 rounds are illegal unless they are blocked to 15 rounds.
