Quit yer bitchin'. You'll have a legitimate issue if they tell you made a mistake and you're sh*t out of luck. That won't happen though.

My bet is they replace the barrel with few/no questions asked, once they get to it.

I used to live 30 minutes away from the factory in NH. I took guns in twice. OnceI needed screws replaced because I screwed the heads up. The other was a gun I didn't even own, but brought in so they could look at a cracked stock. All they have ever done for me is take my gun in the back, and re-emerge 20 minutes later with a replaced part and a repaired gun. Since I moved, I have e-mailed them, and they always return the message within a week.
