Just to clarify, I was not posting the question to take a dig at CMMG, in fact just the opposite. I didn't want to jump on the phone and complain about something that might not even be an issue at all. Last thing I want to do is send it back if nothing is wrong with it.
That said, I am very impressed at how Jeff jumped in and immediately said to send it back. No questions, no excuses. In fact I still hadn't decided whether it was worth contacting them at that point, but he is obviously concerned about his customers' satisfaction and wants them to be happy. If any of my local dealers had ever given me that kind of treatment I wouldn't have even needed CMMG in the first place.
Fact is that most of the dealers I have worked with are small shops trying to eek out a living like everyone else and if they don't have to swap out a barrel and give away a few bucks they won't, can't say I blame them, but in the long run it works against them. Also, I could have probably scoured the net to find a barrel a few bucks cheaper, but do you think they would have given a crap at all about whether it met my expectaiton or not? Probably not.
CMMG came highly recommended and now I see why. If they treat all their customers like that then they are the exception and not the rule and certainly they are worth doing business with in the future.
I also ordered a Vltor rail from them and will post some pics and a full review of my experience when my build is done.
Thanks for everyones input.
