I have trouble hitting targets too... Didn't always, but stutter, freezes and lag have only gotten worse over time. If you have game sense, use your knowledge of the map and the element of surprise. JG is great for waiting around corners. If you get the first round off point blank, you can usually use your opponents panic to circle around them and get a second round off in time or finish them with a perc. Opgl is also good if you use lure tactics. You can lure someone into a tight space with your secondary, run from them and drop some nades as you run. If you time it right, they are like land mines. Or you can always camp with an osmaw or volcano. I am warning you however that people will hate your guts and call you trash... but that's apb for you. In the end, it's not the weapon, it's how you use it.
