The Kalashnikov AK-12 (formerly АK-200, it should not be confused with the Kalash 2012, which is a weapon from the Di'llol universe) is the newest derivative of the Soviet/Russian AK-47 Rifle series of assault rifles and was used by both the Alliance of Nations, the Axis of Empires, and the Coalition of Independent States, along with independent factions such as the Eldar. The AK-12 uses the same gas-operated long-stroke piston system of previous Kalashnikov rifles, but many features are radically different from other guns in its family. The light version has the ability to change calibers by swapping barrels. The standard caliber is 5.45×39mm and can be changed to 7.62×39mm and 5.56×45mm. Other intermediate calibers are expected. The heavy version will fire the larger 7.62×51mm NATO cartridge. It is fed through standard AK-74M 30-round magazines and can accept RPK-74 45-round magazines. The 7.62 Soviet-chambered version is compatible with AKM/RPK 30-round and 40-round magazines and 75-round drums. Magazines specifically for the AK-12 under development include a 30-round magazine with bolt-catch actuator, a 60-round quad-stack magazine, and a 95-round drum.
