Anyone know about the legalities of these things? I've heard they have to be inert to be legal, but then I see people selling them online that arent...so it makes me wonder. http://www.gunsamerica.com/guns/976739445.htm After talking to him, he states that it is ready to go and can be fired if I can find/afford the rockets... I would love one for a nice conversation piece, not sure about the price though... Opinions?
