Great popularity among amateur air pistols have gained weight and size copies of military weapons. In the Russian Federation, the Makarov pistol (PM) is widely used, which caused an increased demand for its pneumatic version - MP 654K. The model is unpretentious in application and has a decent muzzle velocity.
In the process of manufacturing the product, elements from combat PM are used, due to which the pneumatics are very similar to the original. A slightly shortened barrel, recessed at the muzzle, mimics a real 9mm caliber. Outwardly, it differs from the PM in that it does not have a cartridge case ejector.
Destination
This air pistol MP 654 is intended for amateur and training shooting with spherical bullets for airguns of 4.5 mm caliber. Shooting is carried out at a temperature of 10-30 degrees.
During firing from a pistol after it has been kept in the curb condition at a temperature of more than 30 degrees, the speed of the bulletcan significantly decrease on the first shots (usually no more than three). Subsequent firing will restore speed.
Technical and operational characteristics
Makarov MP 654 air pistol has the following specifications:
- Bullet speed: nominal 110 m/s.
- Caliber: 4, 5. Standard ammunition is steel (or copper-plated) balls of reduced size, although full-size lead shot can be used.
- Weight: 0.73 kilograms.
- Magazine capacity: 13 bullet balls. A device for attaching and puncturing a CO2 cylinder is also integrated into the store. But the cylinder is enough for 50-80 shots, after which the gas energy will not be enough for a full-fledged flight of the bullet.
- Body: metal, polymer and rubber sealing joints, plastic grip cheeks.
- Dimensions: 169x145x35 millimeters.
- Trigger: double action.
- Barrel: rifled.
- Attachments for the sight: open front sight and rear sight, non-adjustable.
- Fuse: manual.
Manufacturer: Izhevsk Mechanical Plant.
Cost: Approximately $250, depending on exterior finish, accessories.
Scheme and device
Pneumatic MP 654K is similar in operation to the firearm model. Almost no altered trigger mechanism, differing only in the absence of a striker. The magazine has also been changed, which has been modified for loading with balls and fixing a carbon dioxide cylinder.
Makarov MP 654 pistol works according to this principle:
- The CO2 bottle is placed in the store, screwing it in until the needle is pierced;
- in the bottle, liquefied gas becomes compressed, it is located in a sealed chamber;
- lead or steel bullets are loaded into a magazine equipped with a spring-loaded feeder;
- after pulling the trigger, the trigger hits a spring-loaded valve that briefly releases pressurized CO2;
- outgoing gas has a lot of pressure acting on the ball and pushing it out of the barrel at a significant speed.
Standard equipment
Almost all accessories for the product need to be purchased separately. Standard equipment includes instructions, seals (gaskets) with a screwdriver, 200 steel copper-plated balls. For shooting, you need to buy CO2 cartridges, oil for cleaning weapons and a ramrod.
MP 654 users can also purchase these additional accessories:
- bullet catcher (very handy for paper targets);
- holster.
Cleaning and disassembly
As a rule, instructions and manuals are not enough for disassembling and assembling weapons, you need to see the whole process. Training videos can help you understand the disassembly and assembly of the MP 654 pistol.
Note: Complete disassembly may be required after the product has been dropped into water or mud. It is not recommended to unnecessarily disassemble the weapon.
During scheduled maintenanceincomplete disassembly is performed, the barrel and mechanisms are cleaned and lubricated. To do this:
- shop disconnects;
- trigger guard retracts to the left and down - it becomes a delay, allowing you to detach the shutter;
- the shutter is pulled back until it stops and its rear part rises up, then the front of the shutter disengages and it is removed through the barrel;
- return spring is removed from the barrel.
A copper ramrod is used to clean the barrel. The barrel is wiped with a rag soaked in oil and pushed through the bore with a ramrod. As soon as there are no dark spots left on the rags, the remaining oil in the barrel is wiped dry.
The mechanism is cleaned with a dry toothbrush. Oil is added in places of moving units (use an oiler with a long spout or spray from a can).
The design is assembled in the reverse order. The assembled product is wiped from excess oil, but not wiped dry - the remnants of a thin oil film will protect the metal from early rusting.
Preparing the product for use
First, the magazine is charged with balloons and a can of CO2 is screwed into it. The equipped magazine is placed in the handle until it stops, while the fuse is moved parallel to the barrel.
Safety measures
To minimize walking with a loaded weapon, prepare the target in advance. Shots are fired only in the direction of the target, making sure that there are no people in the direction of firing. Beforecarrying the MP 654 pistol must be discharged, for which the rest of the balls in the store are shot and the cylinder with the remaining gas is unscrewed.
During the operation of the gun is prohibited:
- direct towards people with the muzzle;
- store and keep charged;
- disconnect the full tank from the store;
- dismantle the store with the balloon placed.
Also, when the speed of the bullet decreases, which is associated with the consumption of gas in the cylinder, you need to stop firing in time, without firing blank shots without gas. Otherwise, after the magazine is removed, the bullets remaining in the barrel will hit the firing mechanism, causing it to break.
Replacement and repair of parts
It is often necessary to replace cracked stocks and “shut down” springs in an air pistol. When replacing seals, they must be carefully removed from their seats.
Note: do not rush, because this can scratch the contact points of the gasket and metal, which will have a bad effect on tightness.
To eliminate gas leakage, the seals are lubricated with silicone oil. WD-40 automotive fluid is not recommended because it will destroy the polymer material.
To replace the return spring, the Makarov MP 654 pistol is not completely disassembled. More hassle means replacing the supply spring, because you have to completely disassemble the magazine. To replace bursting USM elements, the product is completelyunderstands.
Benefits according to user reviews
The advantages of this design include the simplicity of the mechanism, increased bullet speed and recognizable design. Thanks to this, the MP 654K is one of the most popular pistols among those who like to shoot at targets in the forest.
Due to the quick partial disassembly and easy cleaning and lubrication, labor costs for servicing the model become minimal. Thanks to the multi-shot, you can fire more than 10 shots in a row without being distracted by frequent reloading.
Flaws
The cons, according to fans of pneumatic weapons, include:
- a common problem for all CO pneumatics2, which concerns a decrease in the temperature of the cartridge during frequent shooting and leads to a significant decrease in bullet speed;
- in some models, improvements are allowed that worsen the tightness of the pneumatic system;
- not completely similar to the original firearm: experts will notice that there is no ejector and there is an extra screw with a ring for tightening the spray can at the bottom of the handle;
- cannot attach other sights - except for the laser designator in front of the trigger guard.
Despite the fact that the Makarov MP 654 air pistol has some drawbacks, they are not considered critical for shooting enthusiasts. To reduce barrel wear and increase bullet speed, it is recommended to use lead balls. To increase the tightness, you can do easy tuning, which does not take muchtime. This will allow in practice to understand the device and the principle of how the gun functions. Due to proper care, you can significantly increase the life of the product, because the weapon loves lubrication and cleanliness.
This item can be purchased at any gun shop.
