I found that ad on Gunsamerica when I was doing a search.  I found another one that said:

"Note: if you buy a USR postban gun, it won,t take any magazines except post ban 10 round ones, you can,t thread barrel for any reason, no flashhiders allowed, etc. There may be other reasons not to buy it as 5 people have tried to trade me their USRs for my AUG. "

Where do they come up with this crap?

(PS--the guy with the AUG actually had a fair price on it).
