It's hard to see due to the lack of first person spectating, but the interesting thing is that he never shoots next to him, and that he only damages a particular body part, Using a galil long range is bound to spray. In the video he gets shot completely in the torso, with a minimal ammount of bullets. Due to the recoil and spray shooting only the torso on that range is impossible. I'd say that his aim snaps to the head/torso hitboxes. @ box I was about to say that, but I waited for the video
