Though born of the same line of KBP-designed A-91-series assault weapons (to include the 9A-91 assault carbine), the A-91 assault rifle is a departure in that it utilizes a "bullpup" configuration for ultimate compactness in-the-field. The action is set aft of the pistol grip/trigger group which allows a full-length barrel to be retained within a shorter overall gun body length. The result is a solid Russian-originated weapon that has seen limited acceptance beginning in 1990 with Russian Army and some select police forces.
Unlike other assault rifles, the A-91 is built with an integrated 40mm grenade launcher. This weapon fires various warhead types of the VOG-25 grenade series already in circulation with Russian forces and Russian military customers of the world. All told, the complete system weighs a manageable 9.5lbs while featuring a length of 26 inches with its 16.3 inch barrel assembly. The carrying handle is integral for facilitating transport. Overall construction is of polymers and usual service-duty metals.
Primarily chambered for the ubiquitous Soviet/Russian 7.62x39mm rifle cartridge, the A-91 is also marketed in a 5.56x45mm NATO form as the 5.56A-91. This version varies slightly in overall dimensions save for barrel length and is obviously marketed towards Western-leaning government armies and special law enforcement. In either form, the weapon is fed via a curved, 30-round detachable box magazine inserted into an awaiting well under the aft portion of the receiver - essentially the area making up the shoulder stock. To protect the firer during shooting, the A-91 features an extraction system that ejects the spent shell casings forward and away from the face (a detrimental quality of most bullpup weapons). Additionally, the feature is customizable for left-handed shooters making the A-91 an ambidextrous weapon.
The weapon is given a tried-and-true gas-operated action that utilizes a rotating bolt function to achieve a rate-of-fire of 600 to 800 rounds per minute at a muzzle velocity of 2,350 feet per second. Effective range is out to 1,000 meters with sighting through an included dioptric device.
