At least one of the buyers of STB's replica Carbines has been told the stocks, flips, mag catches, safeties, barrel bands and hammers most frequently aren't USGI, but he has ignored the info and bought another since then, leaving glowing feedback. Maybe these buyers are flipping them to a sucker who doesn't know?
I've witnessed a drunk with an insurance settlement (and another with a wife's insurance settlement) buy until the money is squandered.
