The ARK-545 (Assault rifle, Kalashnikov-styled 5.45 mm) is an assault rifle based on the Kalashnikov platform produced by United Arms Tactical Inc. for the Russian Army because, well.... let's face it, all the weapons produced by United Arms Tactical Inc. have been for Canada and it's allies, and little to no companies produce weapons for NATO and Russia. It's chambered in the 5.45x39mm M74 cartridge, which is the standard cartridge used by the Russian Army, and has been used in limited service with the Russian Ground Forces along side the AK-74M.
