Getting high accuracies in gunmaster isn't hard especially as many of the weapons within the cycle are shotguns.

That one red HSKR stat on 247fp is for the USAS12, a pickup explosive shotgun, has around 9% which isn't high at all. It's just marked as red because people usually tend to kill with the gun's splash damage by shooting the ground and not aiming for a player's torso/neck/head.

If that's all there is to it i really can't see anything suspicious.

I just check they are a couple battle report weird 

http://battlelog.battlefield.com/bf4/battlereport/show/1/931610556751597376/788048851   39 kills - 27 hs  (he unlock something with the ump 45)

 WE GOT A WINNER !!!

pretty sure the status is going to change soon.

it's funny  to see that he got  like   24 hs on his last 400 kills.

but only a couple of old reports (that he got  two month ago)  got an impossible hskr

it seems like he switch is aimbot on torso only.

and his friends  Khaled2018K got his stats reset by ff
