The AK-103 is a modern, Russian-designed version of the famous AKM assault rifle, chambered for the 7.62x39mm M43 round. It combines the AKM design with developments from the AK-47 and the AK-74M, with the use of plastics to replace metal or wooden components wherever possible to reduce overall weight. The AK-103 can be fitted with a variety of sights, including laser, night vision, and telescopic sights, plus a suppressor and the GP-30 grenade launcher
