The A-91 is a Russian bullpup assault rifle developed by the KBP Instrument Design Bureau during the 1990s. It is an evolution of the earlier 9A-91 carbine, primarily designed to be compact, reliable, and versatile in urban combat scenarios. The rifle is notable for its integrated 40mm grenade launcher and the use of a bullpup configuration, which positions the magazine behind the trigger, allowing for a more compact design without sacrificing barrel length.

The Gyrojet is a family of unique firearms developed in the 1960s named for the method of gyroscopically stabilizing its projectiles. Rather than inert bullets, Gyrojets fire small rockets called Microjets which have little recoil and do not require a heavy barrel or chamber to resist the pressure of the combustion gases. Velocity on leaving the tube was very low, but increased to around at . The result is a very lightweight and transportable weapon.
