It is pretty ok in one on one engagements and definitely requires a person to play in core but it isn't great.
The moment you get two people in close proximity to you then you are dead unless you get lucky and one of them is bad and you kill the first guy in the first "burst".
It isn't bad or broken but requires attachments to make it competitive. In KC, fast mags are almost required to stay mobile though oddly/luckily, the laser doesn't seem to tighten up the spread enough to make it worth while. Long Barrel is pretty much required as well.
Sure a person can do well with it, but it isn't a great weapon and you are most certainly at a disadvantage when using it.
