Many use this gun as a sub-machine gun because the F2000 is not well suited for long range firefights
Pros:
a fast fire rate compared to other assault rifles
If a grenade launcher is used with this gun the recoil is significantly reduced.
The F2000's RDS is not effected by an EMP
---------------
Overall this gun should not be used unless you are trying to complete challenges.
I rate this gun a 4/10 and only recommend use of it in Hardcore game mode. If you want to use this gun in core use the grenade launcher to reduce the recoil.

If you want all the technical info check the source
The gun is a beast if you know how to shoot in bursts. Also I too felt the gun was way more manageable with a holographic sight.
Also no offence but that's a pretty shitty guide, most gun guides around here give tips on whether certain attachments are good or not and more detailed info in general.
