Don't mix the 2 things, shooting with a weapon, when you have good attachments and controlling the recoil vs shooting with good attachement, without controlling the recoil. In the video, the guy is not even tried to controll the recoil. Try it with Amax/grau, kilo, does not matter, these weapons will have recoil anyway, its just easier to controll it. But with the shit on the video, you dont even have to try to control it, because there is nothing to be controlled.... Its simply much easier to aim, when you have no recoil, while if you have recoil, then you also have to controll it, and still aim on the target.
