AK-47

The AK-47 is an Assault Rifle variant in Left 4 Dead 2. It can be found mostly in the location of the SCAR in areas where the assault rifle spawns.

Differences
Compared to the M16, the AK-47 has a much smaller magazine, but makes up for this by doing more damage per bullet. However, it seems that its accuracy is worse than the other rifles, as its crosshair is wider than the others'. It also has a longer reload time and a lower rate of fire compared to the regular Assault Rifle, but keeps being fully automatic, unlike the Combat Rifle or the M16.

Also, it appears that AK-47 has the highest chance to spawn, as seen in videos, where the Combat Rifle or M16 are almost never found.

Tactics

 * It is recommended not to use the AK-47 if good accuracy is desired.
 * The AK-47 is good for killing Special Infected at close range such as the Hunter, the Boomer, and the Tank.
 * The AK-47 isn't really meant for killing distant Smokers. That job should be left to SCAR and the G3 users.
 * It appears the the AK-47 can kill common infected with one shot, depending on the difficulty.

Trivia

 * Most of the AK-47s in real life, have a 30 magazine capacity, some new recent models have 40 (like in-game) or even up to 75.
