9A-91 - a modern small-sized machine, created in 1992 in the Tula Design Bureau as a competitor and more technological analogue of the CP-3 “Whirlwind” machine. Automatic 91 and provides a high rate of fire, and accuracy. That is why the small-sized machine 9a 91 is put into service as a melee weapon.
The weapon has perfectly demonstrated itself in the performance of special tasks for the release of captured hostages in enclosed spaces. Therefore, he replenished the arsenals of all kinds of special-purpose units. Of course, 9A-91 will not replace the AK-74, but he has his own narrow tactical niche - this is a battle in the premises in which the enemy carries out fire from the shelter and is dressed in individual means.
History of creation
In the 1980s, the designers of the Klimovskiy TSNII TOCHMASH created unique cartridges SP-6 and SP-5, which not only ensured the speed of a bullet at subsonic speeds from the barrel of the machine gun, which is important when shooting with a silencer, but could also pierce a bulletproof vest. Around the same time, the boom of body armor and protective helmets began all over the world, they became more compact and light.
In the late 1980s, personal protective equipment became an obligatory attribute of law enforcement officers, terrorists and criminals. The idea of the designers Shipunova and Gryazev was that the special forces of the KGB and the Ministry of Internal Affairs would have a melee weapon that could penetrate the enemy’s individual means of protection. They became a small-sized machine 9a 91.
It is noteworthy that the designers immediately laid in the weapon the possibility of using it with a flameless and noiseless firing device, PBS. In addition, studies were carried out on the rebound of bullets.
It was only in the beginning of the 1990s that the works on the automatic machine, which received the index 9A-91, were completed. However, in 1994, the first samples began to arrive in the special purpose units of the Ministry of Internal Affairs, in particular, the detachment of the GYBOP “Lynx” and the Moscow Special Purpose Paralysis Detachment. A little later, 9A-91 began to be delivered to the internal troops of the Ministry of Internal Affairs of Russia.

Modifications of the machine
9A-91 has several modifications:
- It has a fuse-translator on the left side, equipped with a compensator.
- It is completed with a translator of reduced sizes and a silencer. The compensator is missing.
- In 1995, the machine gun equipped with a silencer, as well as a bracket to mount optical sights. That is why the box-translator fuse moved to the right side. There is a variation of this modification, where there is no bracket for mounting optics. The last modification is different with the enlarged dimensions.
It was supposed to equip the weapon with a grenade launcher GP-95, but this attempt was not crowned with success, because the 9A-91 has insufficient structural strength and weight to withstand a fairly strong impact when firing from GP-95. In later versions, it became possible to mount the collimator sight PK-01 and special laser target designators.
