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.
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
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.
The U.S. military primarily uses the M4 Carbine, which is manufactured by Colt's Manufacturing Company under the designation M4. The M4 is a gas-operated, air-cooled, magazine-fed carbine that is widely used by various branches of the military. Other manufacturers, such as FN Herstal and Remington, have also produced M4 variants under military contracts.
You can buy a plastic m4 or you can buy a metal m4
the M4 Sherman
The M16. The M16 entered production in 1960. The M4 entered production in 1984, and was an improvement over the earlier XM-177 carbines.
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.
