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 M3 is the semi-automatic version of the Ar-15 (M4).
The M3 is the semi-automatic version of the Ar-15 (M4).
The M4 is capable of automatic fire, the AR 15 is not
AR-15 = Semi-Auto civilian rifle M4 = Select Fire Military rifle
The AR-15 has a longer barrel, and is semi-automatic. The M4 is a carbine (short barrel) and is capable of fully automatic (burst) firing. The M4 cannot be owned by a private citizen in the US- they were made after the May 1986 cut off date to register full auto firearms.
The M4 is an assault rifle based off it's popular cousins the M16 and AR 15 also assault rifles.
No one answer- depends on your wallet, your tastes, your uses. There are dozens of makers of good quality AR style rifles.
The M16 and the M4 are the US designations for the AR-15 pattern of rifles.
The AR 15 is a rifle, not a caliber. the .223 is a caliber. Usually the AR-15 is made in caliber .223.
Those are M4 profile barrels, and the notch is to accommodate the mounting bracket for the M203 grenade launcher.
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.
no they are different thing...the ar-15 is not a carbine and is mostly used by law enforcement as the m4 is a carbine used by the military...they look very similar and have a set of things about them that make them hard to tell the difference between them..they also have mostly the same functions and stats as well as rpm, (rounds per minute) power, distance rating, and caliber of bullet...does that help?
