M16 vs ak47

Answer 1

The answer is simple.

AK can break through concrete, M16 can't.

Run over AK with Humvee, it still works, M16 will break to pieces.

Bury an AK in dirt, still works fine. Bury an M16, doesn't work.

Submerge an AK in water, works just great. Submerge an M16 in water, jams.

The M16 is more accurate that the AK47. It has a higher muzzle velocity. It has a much higher rate of fire. The weight of a soldier's supply of rounds is much less with the M16.

The AK has substantial impact at 300 - 600 meters. The M16 has very little impact at that range. This is because the AK uses 30 calibre (7.56 mm) bullets and the M16 uses 22 calibre (5.56 mm) bullets. The small diameter causes the bullet to slow from air resistance quite rapidly.

The M16 has a problem (as do all rapid-firing ultralight assault rifles) of overheating when firing long bursts. One method that some American instructors taught their soldiers to destroy weapons that had to be left behind was to fire a full 20 round clip and then push the barrel against the ground. The barrel will warp. The AK is much more resilient.
