Separate theoretical calculations of such a science as countering sabotage activities and terrorism, say that the higher the organization of sabotage and terrorist groups, the more perfect the weapons used against them should be, and the retaliatory strikes - more united and massed.

Until the 70s of the XX century, until a network of anti-Soviet organizations of various kinds was created in the USSR (now it is fashionable to replace this term with the word "anti-constitutional"), the issue of creating high-precision SGK for special purpose units was not so acute. There were isolated cases of aircraft hijacking, prisoners escaping from the convoy, but this was not of a mass character. If the reader remembers, banditry in the USSR was over by 1960.

Therefore, until that time, the units for conducting secret operations of the USSR Ministry of Internal Affairs and the USSR KGB in their tactics used, in the main, samples of small arms adapted for the tactical actions of such special groups.

. Examples of operational use are previously in service with such units SGK "Tishina" on the basis of AKM and "Canaryka" on the basis of AKS74U, as well as pistols PB and APB.

But this did not fully meet the requirements for the armament of such special forces. For example, the dimensions of the weapons used created inconveniences during the final phases of special operations to capture bandits and free hostages, the presence of an automatic grenade launcher in the kit reduced the effective range of fire and limited the resources of use. Therefore, the leadership of the KGB of the USSR and the GRU of the General Staff of the USSR received a task from the Politburo of the Central Committee of the CPSU to develop new systems, which was subsequently successfully carried out. At present, the armament of special units of the FSB of the Russian Federation and the Ministry of Internal Affairs of the Russian Federation is represented by modern types of special weapons that meet the assigned tasks of these groups to counter a potential enemy.

The art of organic interweaving of seemingly contradictory performance characteristics of a sniper rifle and an assault rifle only emphasizes the talent of Russian gunsmiths who managed to solve this difficult task.

One of the prototypes of modern SGK was the Kanareika silent rifle-grenade launcher (SGK), which had the following tactical and technical data:

AKSB 74U (silent AKS - 74U) with BS-1 grenade launcher

Barrel caliber 5, 45/30 mm

Shot - 5, 45x39

Weight without a set of weapons - 5.43 kg

Length with a butt for shooting with a stop - 900 mm

Firing range (sighting) - 400 m (both a bullet and a grenade)

Flight speed of a grenade - 105 m / s

The clip of the machine gun -20 or 30 shots, the grenade launcher - 8 special shots.

Set

The set of the silent shooting-grenade launcher (SGK) "Canaryka" includes

AKSB 74U assault rifle with PBS-4 device, US74U special cartridge, BS-1 grenade launcher with a shot, propellant cartridge and clip - magazine

In this oversized SGK, which is structurally executed on the AKS 74U platform, not only two types of shots (grenade and small cartridge) are combined, but also two main indicators of a decrease in the sound characteristics of a shot - the spread of gunpowder gases and their localization.

An assault rifle with a shortened barrel (modification of AKSB 74U) is adapted for the use of the BS-1 30-mm silent "grenade launcher", which was used in the Tishina SGK complete with an AKM assault rifle with PBS-1, where it showed good test results.

The grenade is inserted into a grenade launcher barrel, which works on the principle of localizing powder gases, from the muzzle of the barrel. The flight of the grenade is carried out by pushing it out with a piston under the action of a propelling cartridge created on the basis of cartridge 7, 62x53R. A clip for 8 such ammunition is designed in the grenade launcher handle, cartridges are fed manually and sent out using a bolt that moves in the longitudinal direction. The standard grenade SGK "Canary" has a cumulative effect, providing the penetration of 1.5 cm - a steel sheet with subsequent spraying of hot gases, creating the so-called. "Cumulative effect". The grenade launcher weighs 1.7 kg. The assembly aiming frame of the product is structurally fixed on the bracket of the mechanical aiming device of the machine gun, which uses a US bullet for firing with an initial velocity not exceeding the sound threshold. To reduce recoil when firing, the butt pad of the applied part is equipped with a rubber shock absorber.

The PBS-4 silent and flameless firing device, which is lightweight, is mounted on the barrel of the assault rifle. Without an obturator made of rubber materials, firing is carried out both with regular cartridges and with US ammunition.
