What is the best gun on COD Black Ops 2?
Each weapon has a range advantage and disadvantage, but the maps make the SMG dominant and the accuracy of the MSMC make it the best weapon overall. Best is a matter of opinion, and perhaps a camper might say AN-94 or M8A1, but the MSMC is generally the most consistent weapon you can use if you are moving around.Black Ops 2 is the only Call of Duty I haven't played the multiplayer. So I copied this answer off another website. Hopefully it's helpful.
Why do people even ask these kinds of questions? anyway each guns hvae their pros and cons there is no "best" gun just one that you manage to learn how to develop and handle.
AN-94 or pdw
My favorite setup it an94 with grip and suppressor and as my secondary as the dsr 50 with no attachments and it make a good rushing weapon idk about camping cause I'm not a camper. I also like the Msmc and the m27
