M4/M16 overrated in Modern War?

[Outlaw Josey Wales]

I was Infantry 78-82, Reserves 82-84, Infantry again 91-95 and National Guard 95-97. The first time I was in, I used the M16A1 and never had a jam. The second time I used M16A2, liked it better for the 3 round burst over full auto in the A1 and never had a jam. If kept relativiely clean and oiled, should almost never be a problem. Anything past that I would say was because of the climate it was being used in and most likely not properly designed for it.
