I've always had a fondness for the HK G11 personally

A revolutionary new concept - perfected - with nothing comparable internationally
In the development of infantry small arms the fact that the problem of effectiveness could not be solved satisfactorily showed that the concept of a weapon/ammunition system such as the G11 meant tackling paths previously unexplored. Assault rifles in service around the world today are too heavy as individual weapons due to the caliber. Their recoil is excessive and it is impossible to keep them aimed on targets during sustained fire. Bullet trajectories today are also too high and do not fill current needs. <span id='postcolor'>
I assume there will be a bunch of posts flaming the weapon in a matter of minutes, So I'm gonna suggest an off-topic weapon so it can be flamed at the same time for future reference....and notice i said "off-topic"
What about the HK CAWS? That would be a nice close quarters combat weapon.
Although not in that time era nor an assault rifle, it's a hell of alot better then the poor excuse for shotguns we have available in multiplayer at the moment. And you can aim with it atleast unlike the Kolzice
