I have received all of my items from the great Centurion Group Buy. I have some parts already purchased but for the first time ever, I am stuck on a barrel for this build.

Hers is what I have planned or already have for this build....

Centurion Lower, Upper receiver and 13" CMR handguard.
Centurion BCG
Colt Lower parts kit and Receiver Extension
Geissele Super Tricon Trigger
Geissele Airborne Charging Handle
BCM Stock and Grip
DD Fixed front sight
KAC rear sight
Trijicon MRO on Sphur mount
Dead Air Sandman K suppressor and mount...

I have no clue what barrel to put on this build. I am leaning heavily toward a 14.5" middy of some type. I was also kicking around a Noveske Afghan barrel but I don't know if i want a stainless steel barrel that will be suppressed most of the time.

What are your thoughts?
Price isn't much of a concern.
I'd like to keep it light but the barrel must also support the suppressor without crazy POI shifts.
