The Soviet/Russian special forces group - SPETSNAZ - briefly evaluated the AO-63 in attempting to replace its less accurate 5.45x39mm AK-74 line of assault rifles. However, the more conventional 5.45x39mm AN-94 was eventually selected and the AO-63 fell to history. The AN-94 began service in 1997 and continues to gradually replace the large numbers of AK-74 currently in Russian military service.
A mock up of the AO-63 appeared in the 1989 Dolph Lundgren vehicle "Red Scorpion". This example was really a South African R1 (a local variant of the Belgian FN FAL) heavily modified for screen time with only the lower barrel being made to fire.
