AK-47 and M16

The Ak-47 is invented by Mikhail Kalashnikov and it is one of the world's most famous weapon because it is cheap and reliable for example if you throw the M16 into a box of sand, the sand will stick to the gun's mechanism and it will be very hard to clean, but if you throw the AK-47 into a box of sand you will need to only shake it a few times and you can safely shoot it without worrying that the gun's barrel will explode.

The M16 is created by Eugene Stoner during the Vietnam War; it is developed from the M14 which uses a round called .50. The M16 is different than the M14 because it uses a smaller round to increase the weapon's accuracy. At first the soldier that uses the M16 thinks that this weapon isn't good as the M14 because it takes more round to kill a person because the size of the bullet is smaller so they threw their guns away and use the Ak-47 that is collected from the Vietcong soldier.

Although the AK-47 is more reliable that the M16, but the M16 has lower recoil because it uses a 5.56 round which is much smaller than the 7.62 round that is used in the Ak-47. Lower recoil means more accuracy because if the gun has lower recoil, the gun will not shake much when shot in full auto, but less accuracy in long range.
