Totally legal in MD, completely illegal to import to the United States. You will not be able to find one here. There MIGHT be a few floating around in Canada, but, again, they are not importable. You would need to shoot it up there. If it "accidentally came home with you", you would be in insane legal trouble if anyone ever caught you.
Wow, I was just pondering if we ever got anything good from China reading the "seeds" thread, and Norinco popped in to my mind right before seeing this title.
