1.
AK
Avtomat Kalashnikov.
An automatic rifle created by Mikhail Kalashnikov, originally implemented and designated AK-47, the rifle design was closely based on the Nazi Strumgewhr-44 (STG-44) (English: Assult Rifle, 1944). Originally chambered in 7.62x39 Soviet, the caliber was changed in 1974 to a smaller, higher velocity caliber because the Russian military felt that it would be better suited against the .223 Caliber used by the United States. AK is also often used to refer to an assult rifle, and often mistake with Ruger Mini-14 and Mini-30 rifles by stupid cops. The rifle often sports a long, banana clip, but can also accomodate small magazines or drum magazines.
