I purchased the Cmmg 16", 1/7 barrel in November of 2012 and have been very happy with it. I was a little leary of the WASP nitride coating, but so far (low round count) no issues.
That being said, I feel that you can't go wrong with the Wilson or any other name brand. You'll pay for them, but you'll have a quality barrel.
Technically speaking most would favor the 1/7 twist, but search out the subject and you'll find a ton of info and opinions out there to help you make a decision.
