That is a 2002 Huntsman. I have seen one like it with a great looking CCH receiver like the BC's. Thought about it a week and stopped back in to bring her home with me, but somebody beat me to it.
The Sidekicks have have that as well, but with a smaller lug. I wouldn't assume that it wouldn't need to go through a FFL, even though it cannot be fitted with other barrels, it still has the NS serial number like the other 2002 rifles and shotguns. Don't see very many 2002's so you might want to call Customer Service on that one.
Can you posts some pics of the side of the receiver, they are sweet looking.
