I just noticed your pics of your KISS AR-15. I have a new Colt 6920 on the way and I have decided that the only changes/additions I'm going to make are a red dot scope and flip up rear sights. Does this make sense, i.e., will the flip up rears work with the A2 front sight? Am I on the right track. Are you USAF? I flew C-130s in Vietnam.
