Judging by the reviews, for some fansshotguns is a topical issue of the possibility to carry out a noiseless shooting. "Is it possible to use a muffler on a smooth-bore rifle of the twelfth caliber?" - many ask. Particularly intensified interest in this topic after watching the movie "The Old Men Are Not Here", in which the protagonist used a similar device.
В статье содержится информация о том, что собой represents the PBS for a shotgun and how to make a muffler for a 12-shot smoothbore gun with your own hands. Under Russian law, civilians do not have the right to use firearms equipped with sound suppression devices. Therefore, the information contained in the article is of purely theoretical and experimental character.
ПБС (прибор для бесшумной стрельбы) имеет богатую history. Since the creation of the first devices, almost a hundred years have passed. In everyday life, these devices are called "silencers", since their purpose is to muffle the sound of a shot. Having equipped the weapon with such a nozzle, you can safely carry out a covert shooting, without fear of being detected by the enemy by sound and by the flame knocked out of the barrel. For a long time, all the documentation related to the manufacture of silencers was classified as classified. A limited number of PBS was used exclusively by the army units of special forces.
Before starting to manufacture a silencer forsmooth-bore gun of 12 caliber, it is necessary to have an idea of what processes occur in the channel during the shooting and what is the cause of the sound. So, after the shot is shot in the trunk, a very hot air stream is formed, which is a shock wave. The speed of its propagation through the channel exceeds the speed of sound. This is the cause of noise. During the motion, the pressure and density of the shock wave increase. Therefore, when it leaves the trunk, a loud clap occurs. The noise can be removed by cooling the propellant gases until they leave the barrel channel. For this purpose, the device for silent shooting has been created.
PBS is a hollow copper,aluminum or steel cylinder. Also for its manufacture, plastic is suitable. Inside the cylinder is equipped with special chambers through which heated powder gases pass and cool.
The devices are attached to the end of the barrel equipped withspecial thread. The weapon, intended for fighters of special forces, mainly does not contain threads, but is equipped with integrated silencers.
Judging by consumer feedback, the use ofa silencer on a 12-gauge smoothbore gun would improve the hunting process. Despite the fact that shooting with such a nozzle would not scare away the game, which would simplify the life of hunters, it is forbidden to use sound suppression devices in Russia. Since it is impossible to legally acquire a silencer for a 12-gauge smoothbore gun, many shotgun owners try to make such a device on their own or turn to gunsmiths.
Anyone who decided to make a muffler on a smooth-bore gun of 12 caliber should prepare:
A muffler must ultimately representa metal tube equipped with sections that swirl the air flow. Prepared body should be filled with aluminum and spacer washers.
They are set in turn. After the cylinder is fully completed, it is necessary to tighten the nut with its second end.
The gases formed during the shot will beseep into the gaps between the aluminum washers. In this case, the heated air flow as it moves inside the cylinder will be broken down into small flows and cooled. The pushed by them projectile will prevent their rapid exit from the channel of the silencer. Therefore, some of the gases, overtaking it, will leak through the gaps in the aluminum washers, where it will cool. Overtake the projectile small air currents, which will be completely cold. It does not push the entire air stream, but its chilled part. Density and temperature of air at the time of exit from the muffler will be significantly reduced.
На оружейном рынке в США вниманию любителей quiet use of shotguns is represented by the product SilencerCo Salvo 12. This device is a silencer on a smooth-bore gun of 12 caliber "Saiga". A modular design is provided for the device. If necessary, the shooter can adjust the noise level. Twelve inches is the total length of the muffler on a 12-gauge smoothbore gun. The photo of this device is presented in the article. The PBC can suppress the noise level up to 137 dB. Use this silencer for smooth-bore guns 12 caliber, with shooting from "Saiga" and "Boar" and any other hunting model shotgun.
В производстве глушителя используется алюминий brand T6 and stainless steel grade 17-4. Outside, the product is covered with a non-reflex anode substance. The American company PBS is equipped with a special adapter, which is an adapter between the nozzle and the muzzle of the weapon. Using the adapter, the muffler is mounted on the shotgun barrel.
The cost of the muffler varies within1400-1500 dollars. The scope of application of SilencerCo Salvo 12 is diverse. Mostly the nozzles are used by hunters who wish to carry out a noiseless shooting. Also, silencers are used in training firing or for self-defense.
Owners of self-made silencers must rememberthat shooting with attachments that suppress sound is contrary to Russian legislation. Those who are not at all disconcerted by this fact are advised to know that the majority of silencers are artificially unreliable. Shooting with such attachments can damage the shotgun or injure the owner.
