OKOK HOLD IT.
To the stupid fuck who made this thread, listen to this.
the original M16 was made 50 years ago for vietnam, and USA isnt stupid, weve improved over time.
We've inproved the M16 so much, right now its at M16A4, With 1 shot, 3 shot burst, and on some models, fully auto. (but its more of a precision rifle)
the M16 .556 calibre assault rifle holds 30 rounds, and most models are fully modular.
which means we have scopes, sights, nightvision, lasers, lights, tazers, shotguns, grenade launchers ETC.
the M4 a1 is a .556 calibre assault Carbine made to be a shorter but still deadly m16, and both are widely used.
They dont jam as much anymore, and a LOT more has inproved.
and the US doesnt ONLY use m16, there are A HUGE variety of weapons, mp5, g36k, ETCETC, etc to the max.
And this 100 round weapon you were talking about sounds more like a light support machine gun (not even in the rifle/m16 class) and we have those. (SAW support machine gun.)
so before you go dissing america's FUCKING AWESOME weaponry that we are pwning the stupid fucking terrorists like you in Iraq (who only had dirty run down small arms like ak 47's which you cant mod very well, and rpg's/bombs {which are cowardly}) and before you start saying that the troops arent doing their jobs right (we killed WAY more of them then they killed of us) stop playing video games and do your fucking homework. noob.\
by the way, look here for SOME of our weaponry.
