I have an 18" middy CMMG.  I have heard they had issues for a while with slightly off center bores.  While not a huge issue in most cases if I want to put a can on it (which I do)  this becomes a much larger issue.  What is the easiest way to tell if my barrel is good or not.

Have a gunsmith check it. ADCO offers this service for $25. You always want to have each barrel checked for concentricy before you mount a can on it.
