Red,
There are several factors beside the barrel quality that will determine if a rifle is sub-moa capable. Quality of ammo being used and shooter ability being just two of those factors. Having shot benchrest for over 10 years I can personally say that if a shooter can't read the wind and other range conditions the best built rifle will not be sub-moa at all times. Please don't take this as a question of your shooting ability. That is not my intent. :-)
