The demonstration model (AK-200), presented to Russian Prime Minister Vladimir Putin during his official visit to inspect the products of the Izhmash arms manufacturing plant in Izhevsk, was apparently a basic AK-74 in standard 5.45×39mm caliber.
In 1991 the Izhmash factory in the city of Izhevsk began full scale production of a modernized variant of the AK-74 – the AK-74M (M – Russian: Модернизированный; Modernizirovanniy or "modernized") assault rifle that offers more versatility compared to its predecessor.
The city's Izhmash factory began manufacturing the AK-47 automatic rifle in 1948, and continues to produce modern variants of the design to this day.
The PP-19 Bizon ("Bison") is a 9mm submachine gun developed in the early 1990s at Izhmash by a team of engineers headed by Victor Kalashnikov (son of famed AK-47 designer Mikhail Kalashnikov).
