Being the local boys, my first AR was a CMMG 16" Midlength with a Medium Comtour barrel. It's still my go-to AR. They're good people. I would have no reservations about buying another CMMG AR.
My main advice for the AR buyer is don't get caught up in buying a Colt. They're nice guns, but about 80% Kool-Aid as opposed to actually offering anything over any other reputable AR mfr.
