Kalashnikov rifle A Kalashnikov rifle is any one of a series of automatic rifles based on the original design of Mikhail Kalashnikov. They are officially known in Russian as "Avtomat Kalashnikova" ("Kalashnikov's Automatic Gun"; Russian: Автома́т Кала́шникова ), but are widely known as Kalashnikovs, AKs, or in Russian slang, as a "Kalash". They were originally manufactured in the Soviet Union, primarily by Izhmash, but these rifles and their variants are now manufactured in many other countries.
