Alright, first u need an m4 and when u do, go to a close wall and do this
first straight up
left
right
then left again until 30 bullets are out
try to practice on a empty server.
and always aim at head or neck
-How to shoot from far distance
when u shoot from far distance u might wanna take off that silencer unless u can shoot really well with it, but u still might wanna take it out.
alright what u do is
shoot 2-4 bullets at a time
always move short movement, stop then move again.
-Silencer
silencer for me sucks dick lol, but use it when u are in a sneaky postition.
