Design

The A-91 retains the simple gas-operated, rotating bolt action and a trigger unit design from the 9A-91, it features a bullpup polymer housing, with an integral 40 mm single-shot grenade launcher mounted under the barrel. The earliest prototypes of the A-91 bullpup were added with the grenade launcher above the barrel, and with a frontal vertical foregrip; current models are fitted with the underbarrel launcher, which serves as a forearm. The A-91 has a forward ejection system, initially developed in Tula by designers like Afanasiev during the early 1960s. In this system, the ejection port is located right above the pistol grip, and is directed forward. Extracted cases go from bolt head through the short ejection tube to the ejection port, and fall out of the gun well clear of the shooter's face, even when firing from the left shoulder. As for now, the A-91 is made in small numbers and, probably, is used by some elite police units in Russia; it is also offered for export and domestic military and police sales.
