I just wanted to add one more comment on the barrel profile of the C7.
The initial C7 barrel was a standard A2 government profile, cold hammer forged, 1/7 twist and chrome lined.
Later, all Diemaco made barrels were Hammer Forged Heavy barrels.
The pencil barrel image is of the Israeli M16A1 with the replacement C7 style upper receiver.
As true Diemaco C7 uppers are unobtainium, this is close enough for my clone
