Alright, I thought that I might share this with you (because two people on xfire really want it).
Ok. The AK-47, the most famous/infamous weapon in the world of guns, a very popular choice for real terrorists, and a popular choice for terrorists on Counter-Strike.
The AK-47 in CS:S is a VERY powerful weapon. 1 shot to the head, helmet or not, will kill. However, it has LOTS of recoil and spraying WILL NOT do anything. I've had countless noobs spray me with their AKs when startled. After I've killed them, I notice that my health is still at 100. Spraying the AK-47 does not do anything. A rule of thumb is to NEVER hold down the AK-47's trigger. Instead, repeatedly click at a slower rate, like about half to a quarter second in between clicks.
Aiming with the AK.
At point-blank, you can hold down the trigger, this is the only exception, they'll probably be dead by the third bullet.
The unlucky sucker at the other end of this gun won't last very long...
Use the CENTER of crosshair at Point-Blank
Mid-Range
This is where it starts to get tricky. Aim with the top of your crosshair.
See how the bullethole is on the top line of crosshair.
Long-Range
Recoil plays a big factor here. Slow down if shooting constantly, and continually aim with top of crosshair.
Recoil made my AK-47 go up a bit.
Getting your headshots.

Close range
No need to adjust. Just shoot if center of crosshair is on opponent.
Mid-Range to Long-Range
Position you crosshair accordingly. Aim with top crosshair line.
SHOOT!
Headshot!
With practice, you can do this much faster and while moving.
