PP-2000.
At close range, the XM8 C is comparable and requires less rounds per kill but accuracy suffers.
With magnum ammo, all the weapons are pretty much the same out to 30 meters. After that, the PP-2000 dominates.
The Uzi is just terrible. It's got a lower rate of fire, less ammo, is less accurate and deals the same damage as the PP-2000.
I see a ton of people running around with the AKS-74U and I have no clue why.
