Iam thinking non-legit, I doubt that the Air National Gaurd has issued pre A1 m16s in over a decade. plus hte triangular hand gaurds are in awful good shapw for a thiry five plus year old service piece. It appears he is wearing a heavy winter weight BDU jacket and summer weight pants (I know in the army that this would get you in real deep kimchee, can't say about the Air Force),Top pressed, pants fresh out of the brass tumbler. The old Pistol belt I can understand, I am sure there are plenty of active duty guys who are using the old style belts today. If this is really a picture of a gaurdsman, then I think the CA NG really needs some work, how in the world are they supposed fight with antiquated equipment, and how would you expect a guy who can't even match his pants to his shirt when he knows he is going to be working in the eye of the public, to remember all of that stuff he learned in basic fifteen years ago?
