It really depends on the situation:
The M4a1 carbine is often used by counter terrorist on indoor operations because of their small size and rate of fire.
The M4 has a burst fire mode rather than an automatic fire mode. It is very effective in urban settings.
The M16 is amazingly accurate and lighter than an AK47. Usually every squad or so has a back up M16a4 incase they are facing an enemy at a long range.
Personally I would take an M4a1
Not entirely. The Marines retained the M16, and most Army mech units opted for the M16A4 rather than the M4.
The M4 CARBINE IS BETTER THAN THE M16.
The M16 assault rifle has a greater range than the M4 carbine as a result of its 20-inch barrel, compared with 14.5 for the M4. The M16 can hit an area target out to 800 meters while the M4 is effective to 600 meters.
M4 is the carbine- shorter barrel
An M4 is a short barreled version of the M16, so yes, they can look quite similar.
The M16. The M16 entered production in 1960. The M4 entered production in 1984, and was an improvement over the earlier XM-177 carbines.
Yes, along with the carbine version of the M16, the M4.
The M16 and the M4 are the US designations for the AR-15 pattern of rifles.
If you mean the US Army, the M16 and the M4 variant of the M16.
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
Not really too much to tell. The M16 has a longer barrel, and the projectiles will leave the barrel with greater velocity for it. The M4 has the collapsible buttstock and 14.5 inch barrel, so it would be the easier of the two to utilise in urban terrain and such. The M16's longer gas system is the more reliable of the two, and the muzzle flash and noise of the M16 is reduced. The operating mechanism is the exact same, except that the M4 and M16 won't use the same return spring or buffer.
The M4 is a smaller version of the M16. It has less range, but it is better for urban combat.
