Sixty years ago, a former tank sergeant named Mikhail Kalashnikov submitted an assault-rifle design to the Red Army for trials. It was selected as the new personal weapon for most Soviet soldiers, and designated Automat Kalashnikova 1947 – AK47 for short. That designation went out of official use in 1959, but to this day “AK47” is probably the world's most widely-known gun name. Just as open-source Linux - the "communist" software, according to Steve Ballmer - has made Linus Torvalds famous, the genuinely communist open-source AK has given Mikhail Kalashnikov a profile at least as high. The AK47 and its successor designs are the most widely-used firearms on the face of the planet.
