Though not a site sponsor, MDTS teaches carbine classes in the NY/NJ area. I'm sure they would go to PA if he could get a full class.
I would say for you to come to a class in NJ but seeing as you are from a state without retarded gun laws you would more than likely not be able to legally have your rifle in NJ or NY. Hell, I can't even take my magazines into NY for a class.
..It was you to me who taught
In Jersey anythings' legal, as long as you don't get caught.
