With many concerned people purchasing guns there has been huge quantities of Kalashnikovs sold. Yet, the frenzy toward the Kalashnikov may not be as pertinent as many people think it is. It could be useful for the buyers to keep in mind the design concept of the ubiquitous gun.
No one will ever question the AK reliability; there is overwhelming evidence of it. This thing will work in about any circumstance no matter how bad the environment or the maintenance skills of the operator. Anyone who has to face a group armed with this effective weapon should be seriously concerned.
This being said it could be of interest to put it back in context to discover its limitations. This gun was developed as an infantry weapon; what is often overlooked is the Russian infantry concept when it was designed (1947) was to put a lot of man power on the line and equip this man power with as much firepower as possible.
