Working with screws
A do-it-yourself muffler for a carbine needs to be attached to the fixation system with something. It is this question that we will consider next. At this stage of work, you need to take care of the screws that will hold the mount.
For more reliable fixation, you can also make an auxiliary wedge. It is inserted into the groove that is closest to the muzzle and holds the fastener system so that it does not ride along the barrel. Only one screw is used for fastening. It is located at the top of the fastener and does not allow it to rotate.
To make it easier to understand, give all the washers sequential numbers, starting with the 32mm ones. The wedge should be placed between the fourth and fifth circles, and the fragments from the first to the fourth can be connected to each other using superglue. It is recommended to use an M10 bolt in order to compress the washers and ensure a more uniform and reliable gluing.
Similarly, fasten the remaining circles together. After this you will have 2 parts. You must make a channel between them to install the wedge.
Also, in the second part you need to make a groove for the cocking lever, and in the first - for the hook, if there is such a need. When processing organic glass, making a muffler for a carbine with your own hands, you must use a drilling machine. She will become an indispensable assistant for you in this process. As a rule, it comes with a wide variety of attachments that will not be superfluous during operation.
In the second part, use a drill to make a hole that will be located perpendicular to the surface, with a diameter of 5 millimeters. In this case, you need to retreat a little less than a centimeter from the edge of the workpiece.
Your next steps on how to make a muffler with your own hands:
1. Prepare a thread in the glass itself.
2. After processing the parts, make a wedge from the M8 bolt.
3. On the surface, closer to the edge at the end, make a hole of approximately 2.6-2.8 millimeters with an M3 thread.
4. After this, you can begin making a wedge from this bolt. Its length should be 22 and a half millimeters, thickness - 4, and width: on one side 7.5, and on the other, on which you made the M3 thread, - 5.5.
5. Place both glass pieces onto the bolt and tighten them.
6. Then insert the prepared wedge into the groove and screw in the M3 bolt from the opposite side. If everything holds up well, you can start working on the fixation.
7. Insert into the M6 thread made in the glass and secure with superglue a bolt of the appropriate format with an M3 thread prepared in its center. This is where you will screw the screw to secure it. You can use 4 of them in order to attach the structure more strongly, or get by with one, since the wedge holds the elements together quite reliably.
8. Connect the two glass pieces using superglue. Do this as carefully as possible so that you do not have the slightest error. Otherwise, you will not be able to insert a wedge into the structure, and fixing this is very difficult and virtually impossible.
The best improvised silencers
Pillow
Car oil filter
They are manufactured on an industrial scale from aluminum, equipped with threaded fittings and filled with paper and metal shavings. And they make excellent mufflers, and the best ones are made from used oil filters. You just need to choose the right adapter between the barrel and the muffler. Most often – 1/2” x28 and ¾” x16. Most of them can be bought online, and also very cheaply - within a few bucks.
And that's it - no more modifications. Set it up, fire 1 sighting shot, and off you go. You are guaranteed a certain number (depending on how quickly the contents of the filters scatter throughout the area) of silent shots.
In addition, when the power supply is already in full swing, it will not be difficult to remove oil filters from abandoned cars. So you will not have a shortage of this type of improvised silencers.
Solvent Trap Kit
Warning If you get caught with any of the above crap, there will be problems. Unless, of course, you try to make everything official. Improvised suppressors are subject to the permitting procedures described above.
Alternative options
Surely many have heard that improvised silencers can be obtained from other objects. Almost from a loaf of bread or potato. So, this is not only nonsense, but also quite dangerous nonsense. The fact is that all the structures described above have cavities into which hot gases can escape. They are not found in solid objects, so the structure will break. At best - separately, and at worst - together with the barrel, receiver and your hands. So there is no need to take unnecessary risks.
Original article: Improvised Suppressors When SHTF: Keeping Quiet When It Counts
From the editor (as an afterword)
There is also a myth that ordinary plastic bottles can also be used as improvised silencers. In some versions of this myth - almost a bottle of water.
To be honest, there is a sound idea here. But just an idea. An empty bottle will not muffle, but somewhat distort the sound of the shot. And only for subsonic cartridges. A plastic bottle filled with cotton wool, paper or something else is a completely different matter. But such a muffler will be disposable and not very effective. In addition, there is another problem - it is difficult to securely fix such a muffler on the barrel. Neither blue electrical tape nor reinforced tape can save you. Additional means are needed, such as thread protection nuts, placed over the ready-to-use bottle. In addition, it will be useful to drill several holes at the opposite end of the bottle so that the gas escapes more efficiently - otherwise the entire structure may break.
And we will remind you once again that we are not in the United States - civilians are not allowed silencers at all. Even improvised and homemade ones. But when the BP comes, well, it will be much more important to survive by remaining invisible than to follow the letter of the law.

Diagram of the design and operation of the Smatcha muffler.
Before firing, the silencer is completely pushed onto the barrel, which reduces the size of the weapon with a silencer. During a shot, powder gases, through holes made in the fixed part, act on the internal partitions of the outer casing, moving it forward. When the muffler body occupies the extreme forward position, it forms an expansion chamber into which part of the powder gases is diverted, in which they expand, reduce the temperature and are released through a series of capillary holes.
After the gas pressure in the expansion chamber drops, the body returns to its original position under the action of return springs installed on two guides located on the sides of the barrel. Having an original design, this shot silencer has some disadvantages:
1. During a shot, the length of the weapon changes and its balance is disrupted. 2. Automatic fire cannot be fired from a weapon, since the pause between shots is less than the time the silencer operates. 3. When manufacturing moving parts, high precision is required, which complicates the technology used. 4. The resulting carbon deposits can cause jamming of the moving parts, which necessitates thorough cleaning of the muffler parts.
Although the efficiency potential inherent in the mechanical principle of jamming is significant, the engineering idea is original and promising. The main directions for improving the design of silencers are increasing the efficiency of noise suppression (further attenuation of sound), reducing weight and size, increasing durability, improving accuracy and accuracy of fire, simplifying the design and manufacturing technology, and reducing cost.
Based on materials from the book “Devices for reducing the sound level of a shot for machine guns.” Konovalov N.A., Pilipenko O.V., Skorik A.D., Kvasha Yu.A., Kovalenko V.I.
Device Description
PBS is a hollow copper, aluminum or steel cylinder. Plastic is also suitable for its manufacture. Inside the cylinder is equipped with special chambers through which heated powder gases pass and are cooled.
The devices are attached to the end of a barrel equipped with a special thread. Weapons intended for special forces soldiers mostly do not contain threads, but are equipped with integrated silencers.
Design
The muffler is usually a hollow cylinder made of metal (usually steel, aluminum or copper) or plastic, containing chambers inside to remove exhaust powder gases. As a rule, the muffler is screwed to the end of the barrel using a thread specially made for this purpose.
Muffler device
There is also an integrated silencer containing gas chambers around the perforated section of the barrel. Such a silencer is an integral part of a weapon, without which its combat use is impossible, for example, a special sniper rifle or a special “Val” assault rifle.
Both types of suppressors reduce the noise generated by the shock wave of the ignited charge, which forcefully pushes the bullet out of the barrel. In this case, the gases enter a series of chambers, where they lose their speed, while expanding and cooling. Having significantly lost speed, the gases then exit the muffler.
According to the internal structure, mufflers are divided into single-chamber and multi-chamber, with a preliminary membrane (detaining gases breaking forward from bullets), with flow swirlers and heat-absorbing elements.
A little about theory
Before you start making a silencer for a 12-gauge shotgun, you need to have an idea of what processes take place in the barrel during shooting and what causes the sound. So, after firing a shot, a very hot air stream is formed in the barrel, which is a shock wave. The speed of its propagation through the channel exceeds the speed of sound. This causes noise. During the movement, the pressure and density of the shock wave increase. Therefore, when it leaves the barrel, a loud bang occurs. Noise can be eliminated by cooling the powder gases until they leave the barrel. For this purpose, a device for silent shooting was created.
PBS for American hunters
On the arms market in the United States, the SilencerCo Salvo 12 product is presented to the attention of fans of the quiet use of shotguns. This device is a silencer for a 12-gauge Saiga smoothbore shotgun. The device has a modular design. If necessary, the shooter can adjust the noise level. Twelve inches is the full length of a suppressor for a 12 gauge shotgun. A photo of this device is presented in the article. PBS is capable of suppressing noise levels up to 137 dB. This muffler is used for 12-gauge smooth-bore shotguns when shooting from “Saiga” and “Vepr” and any other hunting model of shotgun.
The muffler is manufactured using T6 aluminum and 17-4 stainless steel. The outside of the product is coated with a non-reflective anodic 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 an adapter, the silencer is mounted on the shotgun barrel.
The cost of the muffler ranges from 1400-1500 dollars. The scope of application of SilencerCo Salvo 12 is varied. The attachments are mainly used by hunters who want to shoot silently. Silencers are also used for target practice or for self-defense.
Reasons for using a silencer
To understand why the state is introducing a restriction on the use of silencers on civilian weapons, you first need to figure out whether it makes any sense for hunters or athletes to install such a “body kit” on guns and carbines. Here are the main reasons that encourage firearms owners to resort to using this type of choke tube:
- Hearing safety. The noise level generated when firing a firearm is around 150 dB. Of course, you can use headphones to protect your eardrums, but a muffler will be a more practical “accessory.”
- Ability to hide your location. And this is relevant not only for special forces soldiers, but also for civilians, for example, for hunters. In case of an unsuccessful shot at an animal, the shooter will have a chance to shoot again, especially if the hunt is carried out from afar.
- Reduces recoil and/or eliminates flames. Many modern “silencers” are classified as DTK (muzzle brake-compensator). This means that in addition to dampening recoil, such a “body kit” will also perform other useful functions.
Thus, the reasons for using silencers on civilian weapons are not much different from the principles that guide special forces soldiers, military personnel or Hollywood action heroes. However, if in European countries and the USA the use of such a “body kit” on weapons is not prohibited by law, then in Russia this is not so simple.
"Vintorez"
But even these achievements were not enough for our gunsmiths. PBS still remains a universal muffler, not without its shortcomings. The seals still need to be changed and cleaned just as often due to increased carbon deposits inside the muffler housing. And during intense shooting, powder gases form a kind of cloud around the shooter, unmasking him.
VSS rifle and AC assault rifle
In the early 1980s, the USSR began developing a new generation of silent weapons under the code “Vintorez”. Nowadays, the image of a special forces soldier with a characteristic silent rifle or machine gun with an integrated silencer is a kind of calling card of domestic special forces. Rifles and machine guns of this series have become some of the most recognizable in the world.
But recognition and fame are only half the story; Vintorez and the family of rifles and machine guns based on it turned out to be very deadly weapons. And that's why.
VSK-94 rifle and 9A91 assault rifle
The same TsNIITOCHMASH took a fundamentally new path, developing the entire rifle and cartridge complex from scratch. As a result, 9x39 caliber SP-5 and SP-6 cartridges appeared. This subsonic cartridge penetrates 8 mm steel sheet at ranges of up to 400 meters, not to mention personal armor protection. Later, armor-piercing cartridges SPP and BP were added to the range.
A silencer of a fundamentally new design was integrated into the design of the rifle itself. It did not require replaceable seals. Its design disperses gases into two streams, which inhibit and extinguish each other, and then are discharged outside much more quietly than in PBS-1. The simple and convenient design provides the fighter with the Vintorez (officially VSS, a special sniper rifle) with the ability to maneuver and effectively use the rifle. For example, in Chechnya, a Russian sniper, disguised in the crown of a tree, was able to single-handedly destroy an entire group of bandits before they realized where the fire was coming from.
SR-3M "Whirlwind" - development of VSS and AS
The “Val” assault rifle was also created on the basis of the VSS, which is distinguished by high-capacity magazines, a handle under the fore-end and a folding butt. Later, in the 90s, new silent systems 9A91 and VSK-94 appeared, which use a circuit with a removable muffler. And these days, the development and implementation of an even more modern small-sized AMB-17 assault rifle for the same caliber is underway.
AMB and AM-17
In this article, we did not touch on other silent systems, but we have created a lot of them - sniper rifles, grenade launchers, and even mortars. We will return to them in a separate article. Only one thing remains unchanged - our country’s leadership in the production and operation of silent weapons. And in this we were ahead of the whole world for a long time.

Silencer for shotguns Steel X-Hunter
On June 24, 2022 in Kharkov at the “Guns Open Day”, the long-awaited presentation of a silencer for 12-gauge shotguns from the Steel company took place. The “Safari” shooting complex, where the event took place, and its guests became witnesses and participants in this event. Those who wished could try themselves as the lucky owner of an X-Hunter by shooting from the Fabarm on which it was installed. Of all those who succeeded, there were no indifferent ones). He was liked by the instructors of the complex and even by blogger Vladimir Starozhilov, who, due to his expertise, also left positive comments.
And now for everyone who is eager to learn about this new product, some dry facts and information:
X-Hunter is a modern modular sound moderator for 12-gauge shotguns from the Ukrainian company Steel. The suppressor will appeal to hunters, athletes and fans of recreational shotgun shooting.
The X-Hunter silencer effectively reduces the sound of a shot to a comfortable level. For example, you can happily shoot in an indoor shooting range or small caponiere without hearing protection, no matter how actively or how much you shoot.
The sound moderator is compatible with pump-action, semi-automatic and break-action shotguns of 12 gauge, which have a replaceable choke or external thread on the barrel on which the device is mounted.
You can shoot with the X-Hunter silencer with any container ammunition, a charge of buckshot, shot or a bullet in a container. This is necessary so that the charge passes safely along the muffler guides without damaging it.
One of the main advantages of X-Hunter mufflers is its design. The device consists of 12 separator blocks; it can be adjusted in length depending on the tasks that the shooter sets for himself. You can assemble a sound moderator from 12, 10, 8 or 6 blocks, making its dimensions half the size. Everything necessary to change the muffler configuration comes as standard.
Also, thanks to the modular design, the muffler is easy to maintain; you can remove carbon deposits from absolutely all internal surfaces of the device using standard cleaning products.
Such a device makes the muffler completely repairable. If necessary, you can purchase any components of the muffler separately.
Thank you very much to everyone who read to the end for taking the time to familiarize yourself with our new product! For more detailed information, you can go to the website at https://silent-steel.in.ua/
We wish everyone good health and good mood, shoot accurately, quietly and always at the target.

How to make a muffler with your own hands
If you cannot afford to buy a sound moderator, and you still want to muffle the sound of a shot from your favorite rifle, then we suggest that you take advantage of the opportunity to make a “silencer” at home. Just follow the instructions below:
- Step 1 - determine the diameter. The diameter should be the same as that of the trunk.
- Step 2 – purchase a muzzle guard. Sold in almost any gun store.
- Step 3 - make partitions. You can use washers or lids for this purpose.
- Step 4 – grind the holes. We smooth the washers and place them inside the cylinder.
- Step 5 – glue the tubes. The inner surface of the muzzle must be covered with rubber.
After this, all that remains is to screw the “silencer” to the barrel and fire a few test shots. If the noise level remains high, it is recommended to add several additional baffles to the muzzle.
