Do-it-yourself air rifle repair. Do-it-yourself air rifle repair How to repair an air rifle
Rifles, pistols can be held independently. This will require care and accuracy when disassembling the device and manipulating parts, replacing them. During repair work, it is possible not only to restore weapons that are in disrepair, but also to improve the quality of their work, in comparison with the original state.
General characteristics
Features of repair of parts of pneumatic weapons:
- To increase the accuracy of the shot, it is necessary to mount the optical sight with a minimum distance from the barrel.
- To increase the speed of a shot from a pneumatic weapon, you can replace the old spring with a gas one. It is suitable even for such weapons, which are rarely used, since it is capable of being compressed for a long time without loss of function. Also, the use of a gas spring will reduce the recoil of the weapon.
- If the accuracy of the rifle begins to malfunction, you need to install a bipod. This device is mounted to the barrel using a special latch. When not needed, it can be easily removed. The bipods are designed for excellent long-range hitting, so they are not needed when hunting or short-range shooting.
- When a weapon does not work at the level that appeared immediately after purchase, it is necessary to slightly update its interior. The trigger shoe moves back a few millimeters. The piston will act with renewed force as the compressed air pressure will increase markedly.
- If there are malfunctions in the operation of pneumatic weapons or the accuracy of hitting a bullet deteriorates, it is necessary first of all to check the degree of wear of the spring. When the partial deformation of the rings is noticeable, the expansion of their distance between the other, these facts indicate the need to replace it. The spring is removed with the help of a compressor, which compresses it, which allows you to quickly remove this element and put a new one.
See the photo.
- In addition to performing the work with the help of which the repair and modernization of pneumatic weapons is carried out, immediately after its purchase, adjustment of the rear of the butt is required. This element can be moved from side to side within 1.5 cm.
- To customize the sight and the ability to adjust the weapon for yourself, and also after replacing this element, it is necessary to twist the screws located nearby. The settings are changed after each shot fired from a distance of 10 m from the target.
Repair and modernization of guns and rifles
This element often wears out in models used for a long time.(for example, in ) . Sometimes situations occur that only rubber rings remain completely suitable for use from the drive.
You can independently perform a radical upgrade of weapons by making a new drive:
- The body is made according to the example of the original, but it can surpass it by 1-2 mm in parameters.
- The stem is created from a dowel that can be purchased for a construction gun. Sometimes they grind it on their own according to the existing model.
- The O-ring does not need to be made separately, the option using a rubber round contour, supplied as spare small parts for a car, is suitable. The movement of the stem inside the rubber element is provided by a return spring.
- A polyurethane gasket is located in the center of the rubber element. First, it is produced as a one-piece cover, then a hole is made in it, in which the stem should be placed.
- The check valve spring is stiffer than in mass production. Observing its optimal elasticity, it is possible to completely eliminate the likelihood of debris getting under the inlet valve, which often happens in standard models.
- The check valve is a brass bowl, made from the calculation of the hole in the plug, but made slightly smaller than it. Inside this element is a fluoroplastic cylinder.
- The main (finishing) elements are the outer and inner sealing rings of the plug. They are made of rubber, when installed, they twist quite tightly. When screwing in the inner ring, lubricate it with a little oil and check that there is no gap. If it is noticeable, the ring should be made a little narrower so that there is no risk of the elastic falling out.
These rules will come in handy for modernization and Glacier, about her.
Often, replacing the drive helps to update the operation of the old weapon, which no one expected to function. Thanks to this method, it is possible to quickly and easily repair and upgrade pneumatic weapons.
Sealing
If any of the elements are installed incorrectly or do not fit well together, severe air leakage occurs, which degrades the performance of the entire system. The main problem leading to depressurization is the work of the rammer.
It has special rubber rings that fit snugly against the surrounding external and internal parts. If they are not installed, you should cut them out yourself and install them into the system. They are invariably present in modern weapons.
The condition of the rubber rings should be monitored regularly. After about 1500 shots have passed, they begin to let air through. As soon as this imperfection is noticed, you should immediately replace the rubber elements with new ones.
Review material about the air pistol Drozd, read.
Replacing the spring
A suitable spring is purchased. When buying, you do not need to pay attention to its length. Only diameter and elasticity matter. When reinstalling, sometimes it becomes necessary to shorten this element. For this, the required number of rings is cut off.
If the owner is not satisfied with the power of the weapon, which the manufacturer has given it, then drastic changes will be required regarding the boring of the heel counter.
In this case, more space is left for the spring by cutting a layer of metal from the inside of the backdrop. Usually the maximum thickness of the cut layer does not exceed 1.5 cm, sometimes a little more.
To enhance the effect, you can sharpen the teeth on the cocking lever if a ratchet is not provided for a particular type of weapon. These manipulations can only be performed when modernizing the metal structure. If it is necessary to increase the area for the spring with a plastic backdrop, you will have to replace it with a metal structure, otherwise a person risks breaking the weapon.

Thrust ring
This element consists of a piston and a sleeve, which are fixed by a thrust ring. If the structure is in good condition, then the gap between them is minimal, with the free passage of the piston in the liner. It is desirable to minimize MO (dead volume), but it is impossible to eliminate it by 100%.
If the MO becomes too large, for example, as a result of flattening of elements from high pressure, it will be necessary to replace the ring.
The new must necessarily be sufficiently firm and elastic. The cross section is preferably square. Unlike a round one, it completely fits into the grooves, so it practically does not stretch or deform.
During the systematic pumping of the lever, an extra hole appears in it. It must be removed by inserting a specially made bushing.
Parts are made of steel. If the manufactured element is larger than the hole, then it is mechanically enlarged to an even larger size.
This part is attached to the base by welding or soldered. The resulting bearing will have a sliding function, while the lever has a reinforced and reliable support.
To prevent the outer arm axis from being excessively bent, it is necessary to replace the front pipe plug, making it close to the diameter of this element.
This element provides a secure fixation of the storage chamber. When intensive pumping is performed, a significant load is imposed on all devices, so a small protrusion on the pipe may not be enough to hold the accumulator. If something goes wrong, you can make and install the retaining ring yourself.
It is made of steel. Outside and inside diameters are matched to the surrounding objects. To ensure the highest functionality, a small cut is made using a standard file. Holes are made in the thickness of the ring wall.
They are kept small and symmetrical. They serve to guarantee accurate fixation of the ring and prevent any movement. Studs are driven into the holes, reliably protecting the structure from any displacement.
In this video, the repair of a pneumatic pistol, using the example of the MP-654K:
Small faults can be rectified by yourself. This is done quickly if you adhere to the following recommendations:
- When the seal begins to leak air, it is easiest to simply replace it. When this is not possible, you should not postpone the repair of the weapon. It is enough to put a lining of cardboard or foil under it. To install this element, you need to pull out the seal for a while.
- To check if the piston ring needs to be replaced, it is necessary to withdraw the piston itself until a clear visibility of this rubber element is revealed. You need to drop a little spindle oil on the ring. After that, the piston closes and returns to its original position. If oil bubbles appear on the surface, then the rubber ring needs to be replaced.
- When a spring-piston air gun is disassembled, it is necessary to lubricate the piston and rubber ring with hyposulfite-molybdenum grease. This will increase the durability of the elements.
- When a situation arises when pulling the trigger does not cause a shot, you need to check the quality of the installation of the screw, which serves for the correct functioning of the structure. You should also check the protrusion of the fuse. If it is bent or leans forward strongly, then it needs to be repaired or replaced.
Conclusion
To obtain a positive result from the repair of pneumatic weapons it is necessary to carry out all actions carefully, to know.
Before upgrading or replacing any elements, you must first measure their optimal parameters and fasten the devices with high quality.
After upgrading or repairing a weapon, it is necessary to carry out constant care for it, then you don't have to worry about problems for a long time. Also check out our article on how to make for the weapons room. Particularly noteworthy is the material of Fr.
The main malfunction of pneumatic pistols in Minsk, Belarus, according to statistics, is a gas leak. Lead to breakage:
1. Failure to comply with the operating conditions of pneumatic guns. Owners of pistols leave cylinders in products for more than 3-4 hours, incorrectly release gas at the end of firing, etc.
2. Natural wear of the silicone gaskets in the gun magazine.
Repair of MP 654K - parts for the repair of pneumatics
You can repair the mr 654k yourself, if you have a repair kit for the product, a factory key, a screwdriver, an awl. When studying the detailed instructions, the repair will not take much time, but if you doubt your own abilities, it is better to contact the specialists.
Makarov 654K pistol repair kit includes 7 silicone rings:
1. O-ring.
2. Ring size 6 by 2.
3.Valve seat flange seal ring (thinnest black gasket).
4. Sealing element of the store.
5. Valve seat ring (smallest, white gasket in the repair kit).
6.Overballoon gasket (second white gasket in the kit).
More details about the location of silicone parts will be written below and in the following articles.
Repair of the MP 654K pistol - replacement of the overhead gasket
Replacing the over-cylinder gasket is the simplest procedure for eliminating a gas leak in a Russian-made Makarov 654K pneumatic pistol. However, it does not always solve the malfunction, despite the apparent simplicity and visibility of a breakdown. As a rule, after replacing the silicone element, the installation of other parts of the repair kit will also be required.
Take a small, thin screwdriver, awl. Remove the magazine from the pistol, turn it so that you can see the needle that pierces the cylinder when loading the pistol and the white gasket that is installed around the needle. Hook the gasket with an awl and carefully, so as not to damage the needle, pull it out of the neck of the gun seal.
After removing the old gasket, it remains to put a new, large white gasket on the pistol repair kit. Gently press it against the neck of the obturator with your finger, but not with your fingernail, so as not to damage the tightness of the part. We take a small screwdriver with a blunt end, seal the gasket with it so that it fits into the right place.
What is an obturator - gaskets and their replacement
An obturator is a metal part of an air pistol that prevents a large volume of gas from passing through at the beginning of a shot from an air pistol. In the Makarov 654K gas cylinder pneumatic pistol, 2 silicone gaskets are installed on the obturator:
1.Overballoon, large white gasket of the repair kit, the replacement of which was mentioned above.
2.Black O-ring on the back of the needle of the obturator (for replacement, you will need to disassemble the magazine).
In some cases, it is not the silicone that is to blame for the gas leak, but the needle of the obturator, cracks, chips of the obturator. In this case, you will need an obturator assembly for the Makarov 654K pistol in Minsk, Belarus. When replacing the shutter, it is best to replace the silicone gaskets too.

Stoeger air rifles have appeared on our market quite recently. The range of 4.5 mm spring piston rifles is represented by three lines - Stoeger x10, Stoeger x20 and Stoeger x50. They have different scopes and rifle finishes.
Rifle stocks can be made of wood, covered with a thin layer of matte varnish, or plastic. In order to reduce recoil, there is a rubber butt pad. The Stoeger x10 stock has a simpler shape, unlike the other two, which are notched to better hold the rifle when shooting, one or two cheeks on the stock for convenience, and a nice comfortable rubber recoil pad.
Which rifle should you choose?
The Stoeger x10 rifle comes with a 4x32 telescopic sight on rings, while the Stoeger x20 Combo and Stoeger x50 Combo have a completely different scope with drums for quick adjustments. There is also an adjustable offset. Stoeger x50 is characterized by increased power. It especially attracts buyers with its ease and ease of use, excellent accuracy and accuracy of fire. With such advantages, Stoeger x50 is much more profitable to buy.
Thanks to the reliable spring-piston mechanism, the bullet acquires a speed of 450 m / s. The high-quality steel blued rifled barrel guarantees accuracy and long service life. Fiber optic inserts, one red in the front and two green in the back, allow for accurate hip shooting in all light and weather conditions.
How do I handle my rifle after purchase?
After the purchase, before using the rifle, you need to disassemble it, remove the old grease and apply a larger amount of another. Then put the original or gas spring. After installing a powerful spring, you need to shoot heavier bullets, otherwise the piston hits the bypass with force, as a result of which the springs break and the cuffs burn out.
When self-"de-preserving", securely tighten all the bolts that attach the stock to the barrel. And systematically make sure that they are always tightened to avoid damage to the stock when cocked. It is also forbidden to fire blank shots, which can lead to the occurrence of strong shock loads that disable the optics. And blank shots on magnum rifles will inevitably end in stock breakage. Be careful and attentive when disassembling airguns.
It is not recommended to repair an air rifle with your own hands. First, such a device is potentially dangerous. Secondly, you need special equipment. Companies that repair air rifles accept them only when they are unloaded.
The operation of pneumatic weapons has its own characteristics. Lack of regular care and respect can lead to mechanical damage. The subsequent implementation of repair work will be associated with certain difficulties. It may be necessary to replace cuffs or bypasses, install a gas spring, and straighten the barrel.
To determine the correctness of this type of action, you should first carry out a diagnosis.
Analysis of the technical condition of the weapon allows you to determine the cause of the breakdown and draw up a sequence of further actions.
Diagnostics in most cases is carried out free of charge, and the final cost of repair work will depend on the results obtained.
Fault detection is understood as a set of measures aimed at identifying obvious defects, as well as establishing the possibility of further use of the weapon. This takes into account the level of wear of the working surfaces, the presence of chips and cracks. In addition, fault detection allows you to determine the following points:
- the presence of rust on the metal coating of the rifle;
- traces of mechanical damage;
- the presence of damage to the wooden part;
- curvature of the trunk.
Barrel problems can arise from improper use of the weapon or be the cause of a factory defect. In any case, they should be allowed.
Pneumatic cylinder repair
The importance of repairing a pneumatic cylinder is due to the fact that it acts as the main element of this type of weapon. The pneumatic cylinder consists of a liner, a rod, a piston and flanges. Problems with each of the named parts can disrupt the operation of the entire system. When performing repair work, the design features of these elements should be taken into account. It is very important to regularly monitor that the cylinder does not have mechanical defects from the outside, and that dirt does not get into its internal cavities.
Replacing the cuffs
The ideal option is to use a stiffened cuff. However, after a certain time interval, this element may wear out, as a result of which it becomes necessary to carry out work to replace it. The main difficulty will be that the hard cuff is very poorly put on the piston fungus and quickly becomes unusable when trying to use improvised means.
In case of self-resolution of the problem, it is recommended to adhere to the following sequence of actions:
- Lubricate the piston fungus with a special grease.
- Place the cuff in boiling water (for 30-40 seconds).
- Remove and dry the cuffs.
- Screw the seal onto the piston fungus using a screw-in motion.
- Perform centering.
- Cool cuffs.
If a positive result is achieved after cooling, the cuff can be installed in the compressor.
Bypass replacement
The optimum airgun bypass is equivalent to 3.2mm. If this indicator is less, then the maximum pressure occurs earlier and lasts a little longer. As a result, the bullet accelerates very slowly and sluggishly. The wide bypass ensures maximum pressure at a later date. This provides a short and sluggish acceleration of the bullet.
Bypass seal on Hatsan 125:
Replacing the bypass is due to the need to optimize the performance of the rifle. In this case, it is also possible to resort to a direct decrease in the volume of the bypass or to optimize the diameter of the section of the barrel gasket.
Replacing the mainspring
Replacing the mainspring is due to the fact that during operation this element can stretch. Using a weak spring leads to frequent shooting misfires.
To carry out work on its replacement, you must first remove the firing mechanism.
In some cases, the mainspring can be compressed by a nut to compensate for shrinkage. When pulling off the trigger, hold it firmly.
It is possible to form the spring stop and the slot through which it is best to insert the retainer, presented in the form of a pin, by using a vise. When installing a new spring, remember that it compresses very poorly. The pin can be pulled out after installing the guide. After that, it is necessary to assemble the firing mechanism and check the correct operation of the system.
Gas spring installation
The gas spring is presented in the form of a cylinder with gas, which has a movable rod on one side. This element is pushed out by compressed gas. This creates the force required to move the piston. Replacing a traditional wire coil spring with a gas spring can significantly improve shooting accuracy. The gas spring is installed in this way:
- Removing the axle screw.
- Removing the axial pin of the safety button.
- Removing the stop and all its components.
- Installing a gas spring.
- Installing the centering washer.
- Installation of the stop.
- Screw in the screw.
Installing a gas spring on a Hatsan rifle:
The installation of the gas spring into the piston is most expediently carried out with the rod inside out.
Barrel straightening
The barrel of the weapon determines the direction of the bullet's flight. The smoother it is, the better and more accurate the projectile will fly. During operation, certain problems may arise with this element of the rifle, but the most common malfunction is the swelling of the barrel. The danger of using a weapon with such a defect is that the barrel may burst when fired. Straightening may be required to fix this problem.
Provided that the defect is not too large, the procedure can be carried out without the involvement of specialists. To do this, you need to grind a wooden birch sleeve and insert it from the side of the chamber. It is very important that the wood is well dried.
The straightening procedure starts from the defective spot and subsequently shifts to the center. The blows on the hub should not be too strong, but as effective as possible. You should be very careful about straightening in the places of adhesion. Before removing the bushing, you must first lubricate it.
Setting up the trigger
High-quality adjustment of the trigger mechanism improves the accuracy of shooting and makes the flight of the bullet more predictable. The trigger mechanism is too tight due to the high stiffness of the spring.

The length of the trigger free stroke, as well as the maximum sear and trigger force, can be adjusted. During the commissioning work, certain problems may arise with the fitting of the fuse. You must first remove this element.
Cleaning and lubricating airguns
To clean pneumatic weapons, a cleaning rod with a nozzle and a piece of woolen cloth is used. For this purpose, you can also resort to using special napkins.
There is no need to remove the barrel o-ring during preparation for cleaning. The outer parts of the weapon are wiped with an oiled rag. All movable mechanisms of the rifle also need to be lubricated.
Repair of damaged wooden parts
Wooden elements of pneumatic weapons during operation can scratch, fade and lose their original appearance. The texture and color of the wood used may vary. Repair of damaged wooden parts of pneumatic weapons is carried out using special impregnation and paint and varnish... Thus, you can achieve the creation of a unique texture and come to an optimal color solution. If necessary, the wooden part of the rifle can be darkened.
It is not recommended to use a spray when dealing with this issue. Although for a small adjustment, this substance will be quite enough. It should be noted that it is the real impregnation that is able to provide reliable protection of the wooden surface from scratches and other damage of this type.
Removing bullets from the barrel
Bullets stuck in the barrel of the weapon during firing must be removed as soon as possible. Otherwise, further operation may lead to the failure of the rifle.
The best bullet removal technique will depend on its penetration depth. If it is not too far, then you can try to solve this issue with a regular cleaning rod. It is first necessary to remove the barrel and fix it well in a vice. After that, you should resort to using a cleaning rod. At the final stage of the work, it is imperative to clean the barrel well.
Heat treatment and welding
Heat treatment makes it possible to increase the strength of the materials used for the manufacture of individual elements of pneumatic weapons. There are several variations of heat treatment, including hardening, annealing, normalizing and tempering.
The whole point of hardening is to heat the metal to maximum temperatures, followed by instant cooling. As a result, strength indicators tend to grow.
An equally important role in the production of weapons is assigned to welding. The high quality of the connection of individual elements is determined by the reliability and safety of the rifle.
