The 3 on the left are select fire, the 3 on the right are semi auto.
The AR 15 is a very early rifle. I also have a later AR 15A2 with the round hand guards. The CAR 15 is all original GI parts that I sent home - stripped out my CAR 15 and shipped the parts home - that I put on an early AR 15 lower.
The problem with the M16 was not in the gun, but solely the fault with the ammo having the wrong powder for the tropical climate. The military in its inherent wisdom, once they ID'd the problem set about solving it in typical fashion. They 1. added the fore ward assist to the upper. This allowed you to jam the stuck round into the chamber and gave you one more shot before you no longer had a working rifle (until you disassembled it and cleaned it good). When this didn't solve the problem they then changed the powder in the ammo. Problem solved!
I have managed to qualify Expert with the M1 Garand, M1 Carbine, M14 & M16. Only got 2nd best with the stupid ass 45 auto because I had to shoot it the Army Way. With my 45 shooting like I was used to I would most likely have also qualified Expert, but ---
