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.
Either an M4A1 or M16
The M4A1 carbine is chambered for the 5.56x45mm NATOcartridge, the same as the assault rifle it was derived from, the M16. It is also capable of firing the .223 Remington sporting cartridge.
BB guns like m16 m4A1 And pedro for a cannon
There is no difference! A m16 or any other gun must be blowback to work. Are you talking about airsoft or something, it does not matter. So a real m16 is already blowback, cant change that! and if your talking about airsoft it does not matter
M4 is the carbine- shorter barrel
its the m16 family including m4a1 carbine aka m4 carbine
The M4A1 version of the M16 rifle has a muzzle velocity of about 2900 feet per second, firing the 5.56mm cartridge.
The M4A1 is generally considered to be a better weapon than the M16 due to its compact design, better maneuverability, and higher fire rate. It is also more versatile and can accommodate attachments and modifications. Ultimately, the choice between the two depends on the specific needs and preferences of the user.
