An M4 carbine would be better under almost all circumstances. It is lighter, more accurate at range (Assuming both have their stock sights), and more controllable in full auto mode.
However, the AK47 is a cold war-era weapon while the M4A1 are much more modern. A more debatable and relevant question would be "Which is better, an M4 or an AK74?"
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 M4 CARBINE IS BETTER THAN THE M16.
AK47s or really any other variant costs pretty much the same as an M4/M16. Although I don't really know how you can buy any decent gun for 55 quid.
It all depends of the company making it. A Tokyo Marui M1A1 Thompson would be better than a cheap Wal-Mart M4. But a Classic Army M4 would be better than a CYMA M1A1 Thompson.
The AK 47 Is Better Then m4
AK47s and tanks.
The G&G Combat Machine M4 is the best
Many different companies make Airsoft mac 11 and m4's. However, the M4 models are generally a better all purpose weapon, where the mac 11 is only good for very very close quarters combat.
Depends on intended use.
AK47s
Most airsoft battles take place in close quarters which is what the m4 was made for. Unlike the m16 which was made for longer ranges
