I think thats quite obvious, dont set the aimbot bone to the head but to the upper or lower chest. Put on smooth aim. No auto fire !! No magic bullets. I suggest to fire off 4/5 bullets after every kill just to smooth out and balance your accuracy. You cannot have a 25% + accuracy on an assault rifle, its a dead give away. Also visibility aim is also important, you dont want to track people behind walls and make sudden 180 degree spins because some guy is behind a wall

Good luck, i've hacked for over 300 hours on my bf3 hack and more then 120 hours on bf4 and nothing. Just keep a low profile and make sure to see if the hack is not detected
