So I was talking to my FIL yesterday at a family event and he mentioned that he got screwed on a gunbroker deal. I don't have any experience with them so figured I'd ask you guys on advice to help him out.

Long story short, dealer shipped gun, something happened at post office (they called him because it was "floating" around and wanted to know what to do with it) and it never arrived at his FFL. Dealer is saying FIL is a bad buyer and never paid (check has been cashed) and they blocked him. He told the post office to ship it as instructed on package but they had it labeled as a "damaged package".

He said GB isn't much help.

This is all a short hand story he told me over dinner. He was just tired of arguing with the shop so he chalked it up as a loss as the gun wasn't an expensive one. I assume there has to be an easy way to resolve this but he made it sound like a he said/she said type deal. Im guessing the post office is zero help and someone there probably walked off with it. But, since the receiving FFL never signed, isn't it still the responsibility of the shipping FFL?
