I don't know, I kinda agree with the people say its 50/50. it's the only weapon I have the problem with.
I know, I know... "aim better", right? I aim just fine with it and even with my crosshairs right on a player it's very iffy if I will even get a hit marker.
Very disappointing because I can sometimes get some impressively long kills with it. I just can't seem to get the closer range shots to connect that much. Even when I sneak up behind someone and know my crosshairs are 100% square on the other players back and I am close, it typically doesn't even get a hit marker.
I would normally put it off as lag but it's the only gun that does it for me and it's every time I use it.
It was my favorite weapon in MW3 and my first golden weapon so I am really trying to figure this gun out.
