In real life the first made M-16s were okay. They jammed frequently, ought to the wrong powder being put in it and when it first came to Vietnam people thought that it wouldn't have to be cleaned. The newer versions of it didn't jam often because they replaced the ball powder with the original DuPont IMR powder and had a 30 round clip. They replaced the M-14 as the standard rifle for all infantry, due to it's lower cost, lighter weight, less kickback,and a faster rate of fire.
In Vietnam, the M16 had the upper hand over the AK-47. It could fire over twice as fast, weighed 2/3rds of the AK-47, a soldier could carry twice as ammunition, the stock was made of steel doing more damage than the AK-47's wood stock, almost did as much damage as an AK-47, had a much further range, far better accuracy, and unlike the AK-47's high kickback and muzzle climb, the M16 had no kickback.
M-16 is still the U.S. standard rifle today, although it has had mass improvements since Vietnam use. Some parts were also made of plastic giving it a space age look at the time.
