Relatively new weapon at the time, shorter range than M-14, but more payload.
Advantages of M-16
- Higher Payload
- Faster Rate of Fire
Advantages of M-14
- Higher Range
- More Stopping Power
In real life, the M16's had many positives and negatives. Commonly known is that they were extremely unreliable. This was due to lack of maintenance and cleaning, the wrong gunpowder being used, and barrel corrosion. Despite this setback, the M16 did have its advantages. It fired the 5.56x45mm NATO round, which is a very lightweight round, so the user can carry much more ammunition and can fire much more controllably. Even though it was light, the 5.56 has impressive stopping power due to it's yawing or tumbling effect; on the other hand, it lacks penetration.
The M16 itself is much lighter than the AK-47 and M14 and was much more sustainable when firing, even at its much higher firing rate. It exceeds the AK-47 in both range and precision. It also has a bit more stopping power than the AK-47, yet has only slightly more than half the penetrating power of the AK-47.
It wasn't until the M16A1 came out that the M16 truly shined. The reliability problem was solved. Cleaning kits were issued, barrel corrosion was prevented by adding chrome lining to the barrel, and the M16's original gunpowder (the only one it was approved to use), IMR gunpowder, replaced the ball powder the military had been using.
