A Marine acquaintance of mine in his retirement manufactured suppressor friendly, guaranteed 300 meter accuracy, AR-15 5.56 mm uppers for a number of US Government 3 letter agencies. He was using 1 in 7 twist, heavy profile, quick twist on/off suppressor style barrels and found that his uppers were invariably more accurate at the proofing distance with the suppressor on the barrel. Thus, your idea of getting a barrel assembly dedicated to a dual attachment point .308 suppressor makes great sense to me. I would also suggest that due to the fairly significant end of the barrel heavy beam moment type of mass of the .308 suppressor that you get the absolute heaviest barrel possible in order to mitigate the tendency toward increased barrel harmonic movement.
