So I left the gun there. The smith's, no not the guys for The Matrix, had gone for the day. I have asked that they switch out the barrel with another gun and send me on my way. Had to explain the them that the barrel is not a gun and thus I don't need to do another 4473. The damn wait yesterday was 45mins for the 4473 BTW. I keep you up on what happens. I'm calling in the am to see what they have figured out.
