Well, I built everything else as far as the upper goes and changed out the trigger in the lower. Lapped the receiver, bedded the bbl, checked port alignment, gas tube alignment, etc. etc. Same as on the AA rig except that I assembled the lower also on that one and the 5.56 rig. Hopefully this is the only time I run into a long ext. tube, but you can bet I will be checking from now on.
