The AK-107 is a Russian 5.45×39mm assault rifle developed from the AK-100-series. It features a "balanced" operating system, similar to that used in the AEK-971. In this case, the designation AK does not indicate Avtomat Kalashnikova but Alexandrov/Kalashnikov. The revised designation indicates the incorporation of a new gas system, designed by Youriy Alexandrov, for Kalashnikov-pattern rifles.

The AK-100 family is a series of Kalashnikov rifles, based upon the AK-74M, intended for export sales. The family of rifles offers the AK-74M system, in multiple cartridges and lengths.
