Factbox: The M4 and AK-47 Compared

Taliban fighters in Afghanistan are attacking U.S. Army soldiers with AK-47s, while the army relies upon the M4 Assault rifle. The AK-47 uses a larger bullet, which leads to more kickback upon firing. Some reports indicate that the U.S. Army is looking to upgrade the weapons being used in Afghanistan to larger caliber guns.

Here, the differences between the two weapons.
