The SKS packs a bigger round (7.62mm) than the m16 (5.56mm) but the m16 has a higher magazine capacity, better accuracy,and a higher rate of fire, so the SKS is more powerful, but the m16 is generally regarded as a better weapon.
yes and no the m16 veitnam was auto the one to day is 3 round burst
5.56mm
Yes it does.
the standard m16 shoots the 5.56mm, but it can be converted to shoot 9mm, 7.62mm, even .308
Magazines for the M16 are made in 20 and 30 round capacity.
Both guns are very excellent guns, but it just depends on the situation. If your in confined spaces, the m4 would be better due to its compactness; but if your outside, the m16 would be better due to its accuracy. Overall, I think the m16 is better, but that's just my opinion. Besides, there are better guns than the m16 series such as the m468 with its heavier round, and the scar with its interchangability between the 556 round and the 762 round.
The M16 assault rifle is chambered for the 5.56x45mm NATOcartridge. It can also fire the civilian .223 Remington round.
the bolt will remain open
Yes
Depends mostly 3 round burst though can be fully aoutomatic mos accurate with da 3 round burst
The M16 assault rifle was originally issued with STANAG magazines with a 20-round capacity. However, a 30-roundmagazine has now become the norm. 100-round Beta C-Mags are also available. But of course, only one round can be chambered at a time.
