The A-91 bullpup assault rifle (also known as A-91M) was developed during the 1990s by KBP (Instrument Design Bureau) in Tula as an offspring of the A-91 family of compact assault rifles described in the 9A-91 article. While the A-91 retains the basic gas-operated rotating bolt action and a trigger unit design from 9A-91 it features a bullpup polymer housing with an integral 40 mm single-shot grenade launcher mounted under the barrel.
