Mikhail Kalashnikov passed away today, and for a lot of people, they don't know who he is.

Mikhail Kalashnikov was an general for the Soviet Union, and a small arms dealer who developed guns, around 150 different models, including the AK-74. He is renown for developing the AK-47, or as we affectionately call it, the "AK".

The AK-47 is the world's most successful gun in every sense that success can be measured for a gun. There were around 75,000,000 AK-47's produced. Many years later, countless militants are still using the AK-47. Even though we as Americans don't see them frequenting the streets, they are everywhere in the rest of the world. It's like soccer and the metric system.
