You’re spot on — I can tighten it up with a match load or at least a 62 gr bullet. Right now the 55 gr IMI M193 is budget friendly for the range. I have plans to move the Trigicon VCOG from the Colt 6700A4 over to a HK MR556A1 when I find one — USMC is currently using the M27/HK416 and the HK MR556A1 seems to be the civilian version to build a clone off of. I will most likely pickup another ACOG for the Colt 6700A4 down the road.For what it’s worth, I’ve had good results from Hornady Superformance with the 53 gr Vmax in my AR. It’s a bull barrel DPMS with a Timney trigger. I got lucky and ended up with a unicorn AR that shoots exceptional. Had a buddy who bought it to hunt coyotes with and he really hated packing it around and much preferred his bolt gun. I’ll bet if you try a few different bullet weights of some higher end ammunition you can get that gun to MOA or very close.
This Colt 6700A4 (7.99 lbs) is pretty darn heavy with the KAS M5 RAS (.9 lbs) system and VCOG (1.79 lbs) on it — I thought the HK MR556A1 (8.61lbs) would be a bit heavier than the Colt build… nope.
Colt 6700Aq ~10.68lbs (deducting the .791 lbs for the original A2 style hand guards)
MR556A1 ~10.4lbs with VCOG
