This depends on your play style. There is no such thing as a "BEST GUN" in Call of Duty, it all comes down to one's opinion.
I personally think that the gun is good; not great, but good.
If you engage at medium range, you should like it just fine. It's OK at point blank range.
Well since the peacekeeper just came out that really doesn't count. But the best primary for me is the DSR-50 and my best secondary is the RPG. Yea ik it's weird but hey that's me and not u.
The peacekeeper is a sub machine gun on ops 2. All guns in the class must be gold in the class to achieve diamond status. Until the peace keeper is also golden, diamond is impossible.
