the m16... great stopping power!?
Holy shit, you've got to be kidding me.
It usually can't pierce kevlar, and if you get hit by the round, you won't be knocked down, and you'll still be able to fight (providing that the hit wasn't in a vital area).
If the AK was at its RL capacity, THEN nobody would need another weapon.
Except, perhaps the Dragunov SVD, which calibers a pretty big round, very accurate, durable, semi-auto, etc.
Oh, and AR's DO have automatic functions, except the soldiers tend to fire in BURSTS.
The modes on a AR are usually "safety, semi, and auto"
No burst.
the m16 is rightfully underpowered, since to take out a enemy in Combat it actually takes from 2-3 shots.
