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-74 and 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.

The AK-103 is most likely in limited service with select units in the Russian Army Spetsnaz, due to the good armor and cover penetration of the 7.62x39mm, and is already being exported to other countries such as Venezuela. During the Red Mosque siege (2007) in Islamabad, Pakistani special forces used the AK-103.

Differences from the AKM series include redesigned rear and front trunnions, as well as a 90 degree gas block, AK-74 style front sight block, the use of a black ribbed 30-round magazine constructed of phenolic resin (which is AKM-compatible as well), an AK-74-type muzzle brake, and black synthetic furniture with a heat shield.
