This guy is clearly a jackass and a moron. It makes me angry to read his lame communication and it's not even my situation.

I'd tell him to fxxx himself and demand the rifle and the $700 (with interest) back. For that money and maybe a little more you could have G&H rebarrel the rifle. If he refuses, sue him in small claims court. No excuse for that sort of behavior, even if he is the Leonardo da Vinci of firearms (which i doubt).

Good luck.
