Modus has less bloom. Most cap guns have a very noticeable less bloom than the original guns. You wasted your time over analyzing the two guns because modus outguns AKS all the time if you have two players at the same level. You will probably outgun modus if you are a better player while using regular AKS. The reason why people suck with modus and get outgunned is because the bloom is so much smaller meaning they have to be more accurate which many modus users aren't. And, modus has higher dps meaning if you are an experienced player, you will be more likely to win.
