The weapon is intended for special forces soldiers of the Russian law enforcement agencies. Description, device and characteristics of the machine 9A-91 are presented in the article.


The 9A-91 is a modern small-sized automatic weapon designed in 1992. Primary name 9A-91: “submachine gun”. Subsequently, the weapon was officially renamed the A-91 assault rifle complex. Its creators are the workers of the Instrument Design Bureau in the city of Tula. KBP is developing high-precision guided weapons for the Russian Navy and aerospace forces, air defense systems, guns.

About the history of creation

In the 1980s, body armor and protective helmets were widely used. Their production was subject to regular intensive improvement.New models are becoming smaller and lighter. At the end of the 80s, helmets and body armor became mandatory attributes in the outfit of law enforcement and law enforcement agencies. Protective equipment was also used by terrorists and criminals.

Russian designers - Gryazev and Shipunov - were asked to staff the KGB and the Ministry of Internal Affairs with special melee weapons capable of penetrating individual protective equipment. This weapon was the 9A-91 machine gun. At this time, the designers of the Central Research Institute of Tochmash in Klimovsk developed unique ammunition SP-6 and SP-5. These cartridges are able to provide the bullet subsonic speed, due to which the weapon can be used with silencers. This opportunity was laid by designers at the very beginning of the design work on 9A-91.

In addition, it was not excluded the use of flameless firing devices with automatic weapons. Since, when performing combat missions, the special forces officers have to act in enclosed spaces, a number of studies have been carried out by gunsmiths regarding the propensity of SP-5 and SP-6 to ricochet.

About the test

During the testing of the 9A-91 automaton by the commission, its high rates of fire rate and accuracy were appreciated. According to military experts, the new automatic rifle model will not be able to replace the AK-74. Nevertheless, 9A-91 managed to occupy their tactical niche: the weapon was successfully used in indoor battles.

About destination

Due to the excellent tactical and technical characteristics and the small size of the new machine replenished weapons arsenal of Russian special forces. The development of this model of a small-scale product took several years. 9A-91 was recognized as fully operational in the early 90s. In 1994, several units of automata entered the special divisions of the Ministry of Internal Affairs of Russia, namely, the GYBOP “Rys” and the Moscow Special Purpose Paramilitary Police Department. Soon the servicemen of the internal troops of the Ministry of Internal Affairs of the Russian Federation began to use the machines.

About automatics

In 9A-91 uses the principle of removal from the barrel channel of the spent powder gases. The output is carried out through a special hole in the side of the barrel. The machine gun is equipped with a shutter, with the help of which the barrel channel is locked for four lugs. For 9A-91 provides trigger trigger.Automation of this weapon is designed for firing single and bursts.

About fuses

9A-91 is equipped with a flag translator-fuse. It is located on the receiver on the left side. In the future, already in 1995, in the manufacture of new versions, it will be placed on the right, above the trigger guard. The left half of the receiver will be reserved for a special bar designed to accommodate an optical aiming device or a night vision device. For early rifle samples characterized by the presence of a muzzle brake. In subsequent modifications, this element is missing.

About the butts

For the machine developed butt, which if necessary can be easily folded. Weapons in this position are suitable for hidden carrying. In order to remove the butt, a fighter needs only to lift him up and move him forward along the receiver.

Unlike the pistol grip made of plastic, steel is used to create the stock. In an effort to provide a comfortable carrying, 9A-91 equipped with folding bolt handles. Unlike AK, in this case, the slots for the shutter handles are constantly open.

About picking

9A-91 is adapted for the use of removable silencers and muzzle compensators. Initially, the developers planned to equip the machine with a GP-95 grenade launcher. However, tests carried out showed that sample 9A-91 was unsuitable for such shooting: it was too light and not strong enough. In addition to such standard devices as a reversing rear sight and a front sight, the small-sized machine gun can be equipped with an optical and night sight, as well as a laser target designator.

About ammunition

For the machine developed special armor-piercing cartridges of 9 mm. Their slaughterness is enough to punch a steel sheet with a thickness of up to 0.8 cm from a distance of 100 m.
