So people "instructed" you to go to the ATF, the press, pro gun forums, etc. etc. to destroy a dealers name. You won't find much help here. Not the right way to go about it! Sayin s**t like that sickens me Good luck telling the press you got a bad gun!
He should report the incident to the police. Be sure to bring the gun into the station so that they can inspect it for you.
