The main malfunction of air pistols in Minsk, Belarus, according to statistics, is gas leakage. Breakdown is caused by:
1. Failure to comply with operating conditions for air pistols. Owners of pistols leave cylinders in their products for more than 3-4 hours, bleed gas incorrectly at the end of shooting, etc.
2. Natural wear and tear of silicone gaskets in the pistol magazine.
Repair MP 654K – parts for pneumatic repair
You can repair the MP 654k yourself, if you have a repair kit for the product, a factory key, a screwdriver, and an awl. When you study the detailed instructions, the repair will not take much time, but if you doubt your own abilities, it is better to contact specialists.
The Makarov 654K pistol repair kit includes 7 silicone rings:
1. O-ring.
2.Ring size 6 by 2.
3. O-ring of the side of the valve seat (the thinnest black gasket).
4.Magazine sealing element.
5.Valve seat ring (the smallest, white gasket from the repair kit).
6. Over-cylinder gasket (second white gasket of the kit).
More details about the location of silicone spare parts will be written below and in subsequent articles.
Repair of the MP 654K pistol - replacement of the over-cylinder gasket
Replacing the over-cylinder gasket is the simplest procedure for eliminating gas leaks in a Russian-made Makarov 654K air pistol. However, it does not always solve the problem, despite its apparent simplicity and appearance of a breakdown. As a rule, after replacing the silicone element, you will need to install other spare parts of the repair kit.
Take a small, thin screwdriver and an awl. Remove the magazine from the gun, turn it so that you can see the needle that pierces the cylinder when loading the gun and the white gasket that is installed around the needle. Using an awl, hook the gasket and carefully, so as not to damage the needle, pull it out of the neck of the gun seal.
After removing the old gasket, all that remains is to install a new, large white gasket for the pistol repair kit. Gently press it against the neck of the seal with your finger, but not with your nail, so as not to damage the seal of the spare part. We take a small screwdriver with a blunt end and use it to tighten the gasket so that it fits in the right place.
What is a seal - gaskets and their replacement
A seal is a metal part of an air pistol that prevents the passage of a large volume of gas at the beginning of a shot from an air pistol. In the gas-cylinder pneumatic pistol Makarov 654K, 2 silicone gaskets are installed on the seal:
1. Above the cylinder, large white gasket of the repair kit, the replacement of which was discussed above.
2. Black o-ring on the back of the shutter needle (replacement will require disassembling the magazine).
In some cases, it is not the silicone that is to blame for a gas leak, but the seal needle, cracks, or chips of the seal. In this case, you will need a shutter assembly for the Makarov 654K pistol in Minsk, Belarus. When replacing the seal, it is best to replace the silicone gaskets as well.
They are spring-piston rifles of an original design for initial shooting training. For many years, the Izhevsk Mechanical Plant produced classic breakers PSR, PSRM, IZh22, IZh38.
IZH60 is the first rifle with a fixed barrel and a side cocking lever.
The rifle has an original layout (with a slight stretch you can say bullpup), and the IZH60.61 is also equipped with useful adjustments.
The length of the stock, the trigger stroke, the trigger force, and the position of the trigger are adjustable.
Separately, it is necessary to say about the descent. The rifle has a very good 3-part trigger with warning. The trigger force and trigger travel are adjustable over a fairly wide range with 2 adjusting screws (on older versions there were 3 and 4 adjusting screws). The trigger mechanism has an automatic safety that does not allow you to pull the trigger with the cocking lever open
The rifle barrel is unified with other models of Izhevsk recreational rifles. Produced using the method cold forging. The barrel length is 45 cm, the outer diameter is 13 mm, it has 6 grooves with semicircular fields, less often trapezoidal. The type of rifling does not affect accuracy and is a consequence of the use of an appropriate mandrel, and not a reduction in the cost of production, as some believe. At the end of the barrel of rifles produced after 2000 there is a 12*1 thread.
The rifle cylinder is located at an angle of 5 degrees to the barrel and is a through pipe closed at the front with a plug, inner surface executed well, with fairly low roughness.
The piston is forged and has less clearance with the cylinder than in other IMZ rifles.
The piston stroke is 57mm, the standard cuff is 25mm.
The original spring has the following characteristics: wire diameter 2.6 mm, outer diameter 19.5 mm, number of turns 32-33, compressed length 80 mm, free length 210 mm.
A piston weight is included as standard. At the rear, the spring is preloaded with a plug, which is secured by a transverse pin and a pin-axis of the cocking lever. A ratchet is installed in the buttplate, which prevents the lever from returning when it is not fully cocked.
Until 2000, the rifle was produced with a metal receiver, the so-called, but you shouldn’t take everything at word, since that article was created many opinions have changed.
You shouldn’t stuff a spring from the GC or from the Carpathian front fork into the IZH60, then you won’t have to change the connecting rod to a thicker one.
There’s no need to stuff a paperclip into the groove of the cuff; you can put a rubber band there or fill it with silicone sealant.
it is described how to complete the rammer, in principle everything is correct, but on new rifles the rammer already has an elastic band, so there is no need to complete anything. But on new rifles it is advisable to check the seal of the front compressor plug. The elastic band is often damaged due to careless assembly.
All the tips for sealing IZH60 unfortunately are not suitable for IZH61, the problem is that the rings will get stuck in the magazine, and if they go through, they will be caught by the magazine stopper part.
For those who are afraid to throw out the ratchet, I would advise you to take it out and bore the backplate, so that there is about a millimeter left before the pin, then you can install an uncut spring from the MP512, which I think the best option for IL60,61.
To improve accuracy, I advise you to make a muzzle, the weight is selected individually until a good balance is obtained, you can make the butt heavier by pouring shot with epoxy into it.
Many articles recommend redoing the muzzle chamfer. Before doing this, look carefully at the factory one, although it is not beautiful, it is most often smooth, and if the rifling comes off at the same time and there are no burrs, then you don’t have to do anything, especially considering that not everyone can make a good, even chamfer at home .
You can install an optical sight on the rifle. A big plus of the IZH60 is that it is not demanding on optics; almost any optics, with the exception of very left-handed and crooked ones, will work without problems. But this does not mean that you need to put down pencils. Have mercy on your eyes. The minimum reasonable sight would be a Chinese 4*32 s inch pipe
, preferably with parallax adjustment.
The rifle is very convenient and unpretentious to use.
In the class of non-sporting SPP rifles with a power of up to 7.5 J, this is undoubtedly a very strong participant.
I’ll finish with a small selection of links.

Stoeger air rifles have appeared on our market quite recently. Model range Spring-piston rifles of 4.5 mm caliber are represented by three lines - Stoeger x10, Stoeger x20 and Stoeger x50. They have different optical sights and external finishes on the rifle.
Rifle stocks can be made of wood coated with a thin layer of matte varnish, or of plastic. In order to reduce recoil, there is a rubber butt pad. The Stoeger x10 stock has a simpler design than the other two, which have checkering to better grip the rifle while shooting, one or two cheekpieces on the butt for comfort, and a nice, comfortable rubber recoil pad.
Which rifle should you choose?
The Stoeger x10 rifle comes with a 4x32 optical sight on rings, but the Stoeger x20 Combo and Stoeger x50 Combo have a completely different sight, with drums for quick adjustments. There is also an adjustable detuning. The Stoeger x50 features increased power. It especially attracts buyers with its lightness and ease of handling, excellent accuracy and accuracy of shooting. Having such advantages, the Stoeger x50 is much more profitable to buy.
Thanks to a reliable spring-piston mechanism, the bullet acquires a speed of 450 m/sec. A rifled, blued barrel made of high-quality steel guarantees accuracy of fire and many years of service. Fiber optic inserts, one red at the front and two green at the rear, allow for accurate offhand shooting in any light or weather condition.
How to handle the rifle after purchase?
After purchasing, before using the rifle, you need to disassemble it, remove the old lubricant and apply a larger amount of another. Then install the original or gas spring. After installing a powerful spring, you need to shoot with heavier bullets, otherwise the piston hits the bypass with force, as a result of which the springs break and the cuffs burn out.
When “re-opening” yourself, securely tighten all the bolts that secure the stock to the barrel. And systematically ensure that they are always tightened to avoid breaking the stock during cocking. It is also prohibited to fire blank shots, which can lead to strong shock loads that damage the optics. And blank shots on magnum rifles will inevitably result in the stock breaking. Be careful and attentive when disassembling air guns.
It is not recommended to repair an air rifle with your own hands. Firstly, such a device is potentially dangerous. Secondly, special equipment is required. Companies that repair air rifles only accept them unloaded.
