yes that's what I meant about buyers beware... "Gunbroker" not Milspec.. I have seen the same thing on there.. just now I have seen Milspecs M4 photos posted there and sold and even one of my M4's posted and sold multiple times..
If you're referring to Gunbroker, it's awful right now. I've watched 5 M4's be sold multiple times then the user "unregisters" I'm guessing when the buyer pays them. If it's too good to be true, it is.
