The transitions of the rear cylinder 4 into the middle cylinder 3, and the middle cylinder Z into the front cylinder 2 are made at a right angle (see Fig. 1-3, Fig. 15-17, Fig. 20-22, Fig. 28-30, Fig. 32-33, Fig. 38, Fig. 40 and Fig. 41-46). Next, on the rear cylinder 4 (with a larger outer diameter dz), an inflow 5 is performed, in which the rear part, adjacent to the rear part of the rear cylinder 4 z (with a larger outer diameter ad"), is made with a bevel 9 (see Fig. 1- 3, Fig. 38 and Fig. 40).

After that, in the front cylinder 2 (with a smaller outer diameter 4.) of barrel 1, a channel b is made for the passage of a rubber metal projectile 22, and in the rear cylinder 4 (with a larger outer diameter 4 5) b5 A cylindrical channel is made (namely, the chamber 7) with an inner diameter of d5 for a cartridge 10 (see Fig. 39 -

II, I5I), which is equipped with the mentioned rubber projectile 22 of non-lethal action |4), (5). The inner surface 20 of the channel 6 of the barrel 1 is made smooth (without grooves). In the inlet 5, a hole 12 is made for the passage of the pin 13, which fixes the barrel 1 in the rack 14 from longitudinal movements relative to the frame 29 of the weapon 15 (see Fig. 1-3,

Fig. 38 and Fig. 40). On the bevel 9, a hollow 11 is made, while the hollow 11 is made of an oval shape (in cross section). Fig. 1, Fig. 3 and Fig. 38). An annular groove of 17 cm is performed on the middle cylinder C. Fig. 1-3 and Fig. 38). The annular groove 17 is structurally and technologically made with a depth of from 0.0195 to 90-9595 from the thickness of its wall of the middle cylinder Z (see Fig. 3, Fig. 8 - section Г-Г, Fig. 15 and Fig. 16-17) .

The indicated annular groove 17 is made either rectangular (see Fig. 3, Fig. 15-16 and Fig. 20-22), or of any other shape in plan, for example, wedge-shaped (see Fig. 17).

Narrowing of the cone-shaped section (position 8) of channel 6 of barrel 1 to the dimensions (diameter 4.) of the cylindrical section of channel 6 of barrel 1, namely, to a caliber of 5.4...6.1 mm, is carried out in order to make automatic reloading of weapons 15 At the same time, the 5.4...6.1 mm caliber weapon obtained in the cylindrical section of the channel 6 of the barrel 1 will not allow a shot to be fired from a combat cartridge of the Ohm caliber (with a shell bullet - |6Y), which, according to its geometric characteristics, is included in the chamber 7.

Inserts 16 are structurally made of either a symmetrical shape (see Fig. 2, Fig. 3 and Fig. 34-36), or any other shape in plan (see Fig. 37). These inserts 16 are made either of metal or of any other strong material, for example, of ceramics. The specified inserts 16 are made or smaller than 1/2 of the diameter of the channel 6 of the barrel 1 (see Fig. 4, Fig. 11-12, Fig. 14-15, Fig. 20-25, Fig. 28-31 and Fig. 41- 46), or equal to 1/2 the diameter au of the channel 6 of the trunk 1 (see Fig. 27 and Fig. 32), or greater than 1/2 the diameter au of the channel 6 of the trunk 1 in terms of their height p Ge zo In the place of their maximum thickness (see Fig. 26 and Fig. 33).

Structurally, the inserts 16 are rigidly fixed to the inner surface of the channel b of the barrel 1 or in the horizontal plane (see Fig. 2-3, Fig. 4, c

Fig. 11-12, Fig. 15, Fig. 20-22, Fig. 25, Fig. 28-33 and Fig. 40) or in the vertical plane (see Fig. 24 and "-

Fig. 27), or at an angle a to the indicated planes O (see Fig. 14, Fig. 23 and Fig. 26b). The inserts 16 are structurally placed in a plane relative to each other or with overlapping dimensions of the insert 16 in the specified plane in the projection of one on the other (see Fig. 2-3, Fig. 15, Fig. 28, Fig. 3O0, Fig. 3Z3 and Fig. .40) or buttock (see Fig. 20,

Fig. 29, Fig. 32 and Fig. 41-46), or with a gap of 5 (see Fig. 21), or symmetrically relative to each other (see Fig. 22 and "

Fig. 31). Inserts 16 are structurally placed either in the central part of the barrel 1 (see Fig. 2-3, Fig. 15, - with Fig. 18-19, Fig. 20-22, Fig. 40 and Fig. 41-46) or in the area chamber (see Fig. 28-29 and Fig. 32-33), or in the area of the muzzle section (see Fig. 30-31). "" After that, the barrel of a short-barreled small-arms weapon for firing cartridges equipped with rubber metal projectiles of non-lethal action, which is claimed, is installed in the rack 14 of the frame 29 of the weapon 15 and fixed against longitudinal movements relative to the frame 29 with the help of a pin 13, which is pressed into the hole 12 - ( which is made on the inflow 5) (see Fig. 38 and Fig. 40).

As part of the weapon 15 barrel 1 of short-barreled small arms for firing cartridges equipped with rubber metal projectiles of non-lethal action, which is claimed, is operated as follows. -I Insert a cartridge 10 into the chamber 7 of the barrel 1 (see Fig. 39 -- |4), II), which is equipped with a rubber projectile 5or projectile 22 of non-lethal action (see Fig. 40). At the same time, the outer walls of the sleeve 23 will be in contact with the inner surface of the chamber 7. At the same time, the cartridge 10, upon entering the chamber 7, moves along the depression

Ф 11, which is made on the bevel 9 of the inflow 5. When the cartridge 10 is in the chamber 7, the rear part of the cartridge 10 (namely, the flange 25 with the groove 24 and with the igniter capsule 26) protrudes beyond the rear edge of the mentioned chamber 7 no less than on Zmm, and the rubber projectile 22 (caliber 9...9.5 mm) rests on the cone-shaped transition 8, which connects the cylindrical section of the channel 6 of the barrel 1 with the chamber 7 (see Fig. 40).

To fire a shot, the shooter presses the trigger 31 of the weapon 15 with his finger and starts the shock-trigger mechanism 32. When the shock-trigger mechanism 32 is activated, the trigger 33 hits the striker 34 (b) (see Fig. 40 and Fig. 41).

When the impactor (hammer) 34 strikes the igniter capsule 26 of the cartridge 10, the aforementioned igniter capsule 26 is activated and ignites the propellant charge 28 (powder charge) placed in the sleeve 23 (see Fig. 41).

Under the action of the expanding powder gases, which were formed during the combustion of the metal charge 28 (powder charge), the rubber projectile 22 will be pressed into the channel 6 of the barrel 1, namely, into the cone-shaped section 8, which connects the chamber 7 with the channel b of the barrel 1 (see Fig. 41). Next (also under the increasing pressure of the powder gases formed during the combustion of the metal charge 28) the projectile 22 will move along the length 65 of the cylindrical section (with an internal diameter of 44) of the channel b of the barrel 1 to the place of installation of a pair of inserts 16 (see Fig. 42) . After the contact of the metal projectile 22 with the front insert 16 (see Fig. 42), the specified projectile 22 under the pressure of the powder gases formed during the combustion of the metal charge 28 will be pressed into the gap between the front and rear inserts 16 (see Fig. 43 ).

Bypassing the place of installation of the inserts 16, the projectile 22 will further move along the length of the mentioned cylindrical section of the channel b of the barrel 1 to the muzzle 18 (see Fig. 43). At the same time, the friction against the inner surface 20 of the channel b of the barrel 1 of the rubber metal projectile 22 will be compensated by the smooth surface of the specified channel 6 of the barrel 1.

When the rubber metal projectile 22 exits the muzzle section 18 of the barrel 1, the said rubber projectile 22 will expand, assuming its spherical shape (see Fig. 45). 70 After the rubber metal projectile 22 exits the muzzle section 18 of the barrel 1 (see Fig. 46), it will continue to move toward the target at a speed M due to inertia.

The cartridge case 23 is pulled out of the chamber 7 by hooking it to the flange 25 of the groove 24 by the ejector 35 of the weapon 15 when the bolt frame 36 moves back. When the shutter frame 36 moves back, the return spring 37 is compressed (accumulating energy) (b). 15 When the bolt frame 36 moves forward (along the frame 29 of the weapon 15 to the side of the chamber 7), it grabs another cartridge from the magazine 38, sends it to the chamber 7 and locks it there (see Fig. 40) (b.

The weapon is again ready for the next use (shot).

Increasing the effectiveness of using the barrel of short-barreled small arms for firing cartridges equipped with non-lethal rubber metal projectiles, which is claimed, in comparison with the prototype, is achieved by changing the geometry and design of the barrel, namely, by installing two streamlined inserts in the bore of the barrel, which allow passage in gaps through them to a rubber metal projectile, and prevent the use of a combat striking element, such as a bullet of a combat cartridge. Increasing the effectiveness of using the barrel of short-barreled small arms for firing cartridges equipped with rubber metal projectiles of non-lethal action, which is claimed, in comparison with the prototype, is also achieved through constructive solutions, in which it is impossible to use ammunition (cartridges) equipped with projectiles of lethal action (bullets with shell). Narrowing the barrel to the dimensions of the cylindrical section t of the barrel, namely, to the caliber of 5.4...6.1 mm, will allow automatic reloading of the weapon. At the same time, the weapon caliber 5.4..6.1mm received in the cylindrical section of the barrel will not allow a shot from the Umm caliber cartridge, which, according to its geometric characteristics, enters the chamber.
