It was nerfed after 2017 until last year when everything went pre-2017 mods. That nerf decreased it's fire rate and magazine size. I think that is fair to nerf it back down. You have people miss 19 of 20 shots.
I'd rather buff cetain guns instead of nerd ak cause m16 bad HUGE not good enough and mac10 should do more close range damage
m16 2taps headshots with almost no recoil, huge is decent if you just aim for the head and control your spray on close range and mac10 is just kinda a meh weapon overall, if you have skill as a non donator use m16 if u dont use shotgun
M16 has a slow enough firerate that anyone with a ak or shotgun could take you out before getting a second shot so it's almost never better. Also with an ak you can just pull down and you get nearly perfect accuracy.
