Which brings us to the m16 Americas longest service service rifle. Beginning with the orginal m16 to the current m4, furniture has changed we've gone from auto to burst back to auto, shorted the barrel, but the core of the rifle is the same since the 60s.
Today's post skips ahead in time a bit since I do not have a M16, A1, A2, or M4 yet.
Here is a FN M16A4 both with and without the ACOG. This one holds special place for me as I learned to shoot on an A4 in basic. I never held a rifle until drill sgt Fredricks handed me my M16A4
