I wouldn't even begin to consider buying any sort of rifle right now except for a bolt-action hunting rifle. Every thing else is panic-price, but hunting rifles are a drug on the market. Probably be able to buy a good-used rifle at half the asking price at a pawn shop, after hard bargaining.
Better off to buy gold or junk US silver coins and wait six months.
