The AK-47 ( automatic ) was added in the Gun Update, and is an underpowered weapon. When the weapon was first added it had 14 bullets, however recently it was changed to have 30 bullets. Since the change, the damage of each bullet was reduced by twice as much.
The Shooting Range also known as The Gun Shop.
It is recommended to not use this weapon at all due to it being underpowered. This weapon however is useful when the person you want to kill is low on health.
