the m16a1 was first feilded invietnam,later the m16a2 was made to fix some of the mistakes in th a1. the m4 is a carbine version of the a2. 1963 i belive
well eugene stoner is the designer of the m16 and the m4 is just a shorter varient of an M16A2
They are not the same. The M4A1 was first issued to U.S troops in 1997. It is more reliable than the M4 and has a fully automatic fire capability.
The cartridge most commonly used with the M4 is the 62 grain M855 or SS109.
The M4 is a military rifle capable of semi automatic or 3 shot automatic fire. It is used where a lighter shorter rifle is useful.
The standard M4 bolt size commonly used in industrial applications is 4 millimeters in diameter.
The standard M4 screw size is commonly used to secure components in electronic devices.
they are bothe very similar but i would have to say the m4 because of higher power and it is used by the military not like the ar-15 which is mostly used by law enforcement. It depends on the m4 though because there is a very wide variation of models of the m4 unlike the ar-15 which is one basic model... there isn't much difference between the m4 carbine and the ar-15
You can buy a plastic m4 or you can buy a metal m4
the M4 Sherman
m4 <><><> You would have to define better. The M4 has a greater range, the AK a heavier bullet, the M4 a faster bullet, you can carry more ammo for an M4, the AK needs less maintenance, the M4 has a higher rate of fire- and so on.
The M16. The M16 entered production in 1960. The M4 entered production in 1984, and was an improvement over the earlier XM-177 carbines.
