Personally, I think there both wrong. M4a1 can actually one hit kill to the head, i have it on demos and I can prove it. Also the AK is very acurate if your know how to control it. Everyone plays with there crosshair at 5000, 3000, and sizes that are just plain stupid. If you use Large, medium or small you can control your crosshair so much better! How you control your spray is you have 4 lines. You get the left, bottom and right on his legs and just spray.
