I actually watched an Asian (Korean?) dude playing a while back and he would just use an SKS with a RED DOT and a shotgun. Now, he of course was in his most hardcore win mode so he just looted until the 2nd circle, then drove to a shack in the middle of the circle and sat there. Only killing people that came to his door or drove by. He did eventually have to move, but by that time there was 1 guy left and he killed him and won with like 5 kills. Incredibly boring, but efficient. But my point is that he was basically using the SKS as an Assault Rifle. He'd red dot shoot people within 100-200m with it at a pretty fast pace and he was really good at it. I think that's almost it's strong point is in mid range fired in the quickest possible succession. Whenever you TRY to line up a headshot it just seems to fuck you over or just not work at all.
