I don't understand what happened. Why didn't you just send the gun back within 3 days by registered mail?
I looked at his GI listings and the guns he has are, by and large, not real high-end and they are in a price range that will make it not worth your while to initiate a suit.
A friend got screwed on an interstate 100K deal and his lawyer filed a suit in Federal Court and the defendant couldn't afford to defend (he would have lost anyway) but a 20K gun isn't worth it and if fraud was really involved the guys who do it know about the limits they can get away with.
