The AK-47 is perhaps the most widely used firearm in the world. Carried by enemies and allies of America alike since 1947, it is the standard infantry weapon for 106 countries. There are an estimated 100 million AK-47s of a number of variations around the world.

It is a popular weapon among firearms enthusiasts, professional soldiers and terrorists alike. In the United States, it is best known as a "bad guy" weapon, given its history and use among many past foes.
