The method of manufacturing the barrel of short-barreled small arms for firing non-lethal ammunition is carried out as follows (see Fig. 1 and Fig. 2-20). at

The blank 1 for the barrel 2 is pre-made (see Fig. 2). Next, the barrel 2 is hollowed out of the blank in the form of two cylinders of different outer diameter connected relative to the longitudinal axis - (a; and to, where au"d"), while the barrel 2 itself (as a guide for the striking element of non-lethal action) is made smaller diameter (41) than the housing of the chamber Z (to) (see Fig. 3-6 - as a design variant). After that, they drill (for example, with a drill 4) or in any other way make in a cylinder of a smaller diameter "(du) channel 5 of the barrel 2, for example, with a diameter of 5.6...6.5 mm, 8.0...100 mm ( see Fig. 7 - as a variant of the constructive seam

Execution hashes). At the end of the above-mentioned technological operation, drill out (for example, drill 4) or in any other way make a chamber with a larger diameter (and 2) in a cylinder with a larger diameter (see Fig. 8 - as an option)" design, for the "TEREN-3" cartridge caliber 9 mm, which is equipped with an impressive element of non-lethal action - a rubber bullet with a diameter of 9.5 mm (41). Next, the chamber C is connected to channel 5 of barrel 2

Conical transition b (for the purpose of smooth entry of the striking element into channel 5 of barrel 2) (see Fig. 9). After that, in the rear part of the chamber Z inflow 7 rectangular in cross-section shape is made (see

Fig. 4) (at the same time, the rear part 8 of the inlet 7 is made protruding beyond the cut of the end part 9 of the chamber Z - - see Figs. 9-10). The production of the inflow 7 is accompanied by the execution of technological operations, according to which a bevel 10 is sequentially made on the inflow 7 (see Fig. 10), an oval-shaped depression 11 is made on the bevel 10 (see Fig. 10-11), a hole is made in the inflow 7 12 for the pin 13 of fixing the barrel 2 to the rack 14 of the frame 15 of the weapon (see Fig. 11). Structurally and technologically, the hole 12 for the pin 13 fixing the barrel 2 to the rack 14 frame 15

GK) weapons are performed at a right angle to the inflow wall 7 (see Fig. 11).

The technological process for the manufacture of the barrel of a short-barreled small-arms weapon for firing non-lethal ammunition is continued by the fact that after the hole 12 for the pin 13 fixing in the barrel 2 to the rack 14 of the frame 15 of the weapon is made in the inflow 7, an additional hole 16 for the additional pin 17 is made in the inflow 7, which fixes the barrel 2 of the weapon to the rack 14 of the frame 15 of the weapon, while the additional hole 16, which is made in the inlet 7 of the barrel 2 for the additional pin 17, which fixes the barrel 2 of the weapon to the rack 14 of the frame 15 of the weapon, is made at an angle p to the side surface ( walls) of the indicated influx 7 (see Fig. 12). Next, measures are taken to increase the inner diameter 424 of the chamber Z to a value equal to the outer diameter of the cartridge case of the ammunition equipped with a rubber projectile of non-lethal action (for example, by drilling the chamber to a diameter of 1 mm, which is equal to the outer diameter of the cartridge case of the ammunition equipped with a rubber projectile of non-lethal action (4), for example, a cartridge with a length of 20 mm - a cartridge "TEREN-3", which is equipped with a non-lethal rubber bullet, with a diameter of its outer surface of 9...9.5 mm) (see Fig. 13 - as a variant of the design). 65 After performing the above-mentioned technological operations (or in parallel with them, or previously - as a variant of the technological process of manufacturing the barrel of short-barreled small arms for firing non-lethal ammunition), an additional cylindrical insert 18 is made, in which the outer diameter 4 zn is equal to the inner diameter dn of the channel 5 of the barrel 2 , and the inner diameter 4, (caliber) - not less than 2mm (for example, with a diameter of 4.5mm, 5.O0mm, 5.bmm, b, Ohm, etc.) (see Fig. 143. At the same time, after manufacturing an additional cylindrical insert 18 ( or in parallel with the above-mentioned technological operation - as a variant of the technological process of manufacturing an additional cylindrical insert 18 -liner"), an annular groove 19 is made in the front part of the cylindrical insert 18, which creates a stepped transition from the end part 20 of the cylindrical insert 18 to the inner surface 21 of the channel 22 of the insert 18 (see Fig. 15) 3. Continue the cycle of technological operations related to the manufacture of the short-barreled barrel small arms for firing ammunition 7/0 of non-lethal action by taking measures to polish the inner surface 21 of the channel 22 of the insert 18 (see

Fig. 16) and chamber 3.

After taking measures to polish the inner surface 21 of the channel 22 of the insert 18 and the chamber Z, the cylindrical insert 18 is inserted with tension into the channel 5 of the barrel 2 (see Fig. 17) until it connects with the conical transition 6 of the channel 5 of the barrel 2 into the chamber Z (see Fig. Fig. 18).

Next (to fix the barrel in the rack of the gun frame, for example, the FORT or PM pistol (9-mm Makarov pistol, modified for firing with non-lethal ammunition - "VII"), a circular ledge 23 of cylindrical shape is made on the outer surface of the chamber Z in diameter az smaller than the outer diameter to the rear part of the chamber 3, for example, by a value of 1 (see Fig. 19 - as a design variant).

At the final stage of manufacturing the barrel of short-barreled small arms for firing non-lethal ammunition, measures are taken to apply a chemical coating to the surface of the barrel 2 (see Fig. 20), followed by polishing of all barrel surfaces.

The barrel of a short-barreled small-arms weapon made according to the above-mentioned technology for firing non-lethal ammunition is ready for combat use.

The manufactured barrel of a short-barreled small-arms weapon for firing non-lethal ammunition is installed on a model of a small-arms weapon, for example, on the frame (position 15) of a 9-mm self-loading pistol of the "FORT-12" brand or on the frame of a 9-mm Makarov (PM) self-loading pistol (see . Fig. 21), or to designs in which the base model is a 9-mm Makarov self-loading pistol (PM), or to other designs in which other designs of firearms are the base model. з зо Increasing the effectiveness of the method of manufacturing the barrel of a short-barreled small arms weapon for firing non-lethal ammunition, which is claimed, compared to the prototype, is achieved by installing an additional cylindrical insert in the bore of the barrel, which allows a rubber bullet to squeeze through when firing through the barrel and ensures the impossibility the use of a steel (shell) ball, which is equipped with combat cartridges. Increasing the effectiveness of the method of manufacturing the barrel of a short-barreled small-arms weapon for firing non-lethal ammunition, which is claimed, in comparison with the prototype, is also achieved due to the manufacture of an additional hole for the installation of a locking pin, which will not allow replacing the weapon has a barrel designed for a rubber bullet of non-lethal action, on a combat barrel.
