gun help please urgent!!!

AK series is pretty accurate so you can usually burst their guns (bursting is when you click and hold the left mouse button for about 3 shots, then release for a half a second and continue in this fashion,) For longer ranges try tapping (same as bursting, but only do one shot each time.) The best players rarely spray their weapons they always use a combination of tapping and bursting, it might not seem like a good idea in blank range but its better to burst/tap a headshot then trying to spray the whole body and praying you kill them.
