Almost every man wants to own a gun. The presence of a pistol has long been considered a vivid confirmation of a certain status, a symbol of power. But there are two significant problems associated with the acquisition of weapons - the high cost and the mandatory presence of a permit to carry them.

The way out of this situation was the appearance on the arms counters of various models of pneumatic pistols. They look very similar to real combat weapons, but they are much cheaper and do not require any special permission from law enforcement agencies, since they are not firearms. These pistols do not require gunpowder to fire.

The principle of operation of air guns

Pneumatics are weapons fired using compressed air. If in a combat pistol the bullet takes off due to the energy generated from the combustion of gunpowder, then in pneumatics, air flow orcompressed gas. Such weapons are also colloquially referred to as "airguns".

Weapon systems

Spring-piston system. Contains a piston that, under the influence of a strong spring, pushes the air necessary for the bullet to fly out of the bore.

Compression system. It uses gas compressed in a special tank, which is pumped by the owner of the weapon using a compressor or pump independently.

Gas balloon system. Pneumatic weapons do not run on ordinary compressed air, but on flammable carbon dioxide, which is filled with a cylinder at the factory.

In the case of spring-piston and compression systems, if you have certain tools, skills in working with iron, the necessary material, homemade products are allowed. Experts strongly do not recommend the use of a gas-cylinder system in the independent manufacture of pneumatic weapons. This is due to the fact that in this case it will be necessary to work with carbon dioxide, which, unlike air, in a compressed state is very dangerous.

One of the best gas-cylinder pneumatic pistols is the MP-651 pistol. This weapon has many names. Often it is also called: "pistol K", KS, "Cornet"; less often - IZH-651. Such a variety in the names of the MP-651 pistol is associated with the history of its creation.

How was the weapon created?

The first modification of the MP-651 was the manufactureduntil 1998, IZH-67 "Kornet", the mechanism of which was the basis of the entire series of pneumatic pistols. The weapon contains a rifled barrel and a removable drum designed for bullets. This model was characterized as an entertaining weapon with a high accuracy rate. Nowadays, this modification cannot be purchased at a gun shop, since the IZH-67 "Kornet" is considered a real historical value and rarity, which can only be seen in private collections or bought by hand for a lot of money.

The second predecessor of the modern version of the MP-651 was the IZH-671 Kornet. This modification of the pneumatic pistol was intended for firing metal balls. For such shooting, the weapon had a smooth barrel. Due to the fact that the IZH-671 Kornet had a rifled barrel, the power of firing iron balls lost its power. Hit accuracy has also been significantly reduced.

The second modification is also considered a collectible weapon.

The third option was the pneumatic MP-651 K, which is traditionally still called the "Cornet". It combines the two previous options and is an air weapon containing two removable barrels and two drums designed for bullets and steel balls. If the model had a removable barrel and drum, there was a discrepancy between their axes (it was difficult for the bullet from the drum to enter the barrel bore). The use of breech chamfers to eliminate this drawback led to gas leaks, which negatively affected the power of this pneumatic model.

The air pistol MP-651 KS got its second name - "KaStrat" because of the truncated valve hole, which, unlike the previous versions, now has not 2.5 mm, but 1 mm. Users and fans of pneumatic weapons correct this shortcoming with a drill with a 2.5 mm drill. The third option has become more elegant than the previous ones and is the pinnacle of the evolution of air pistols.

Description

The air pistol MP-651 KS is produced in Russia, in the city of Izhevsk. In the factory production of this model, steel is used for rifled barrels, aluminum alloys for weapon bodies and plastic for pistol grips. The weapon has a guarantee for a period of six months. The pneumatic pistol comes with a magazine, interchangeable drums for bullets and balls, a weapon passport.

How does it work?

The MP-651 KS pistol is a weapon using a gas balloon system. The departure of a bullet in it is carried out with the help of compressed gas, which is filled with a special tank. For this purpose, factorycans. For each bullet, a certain portion of gas is distributed, which is enough for the bullet to receive its charge of speed and fly out of the pistol bore. The distribution of portions of gas is carried out as a result of the well-coordinated work of the trigger and valve mechanisms of the pistol that hold the gas flow. After pressing the trigger, a spring-loaded trigger rises, which opens the valve. The MP-651 fires bullets and balls, which, placed in the pistol's magazine, are fed into the barrel bore using a feeder spring.

Air gun trigger

Shooting from the MP-651 KS can be carried out by self-cocking and as a result of installing the trigger on the sear cocking position. If an attached buttstock is attached to the trigger mechanism, shooting is possible by self-cocking. In this pistol system, a non-automatic safety is located on the trigger. Its job is to block the trigger, preventing accidental firing.

Pros and cons

Like any product, the MP-651 KS pistol has its strengths and weaknesses. This variant of the pneumatic weapon, due to significant improvements in automation and its modernization, ensures high accuracy of hits during firing. The pistol is equipped with an elegant handle. The improvement in the performance characteristics of the MP-651 KS, with its relatively low price, has increased the demand for this model among users.

According to some consumers, this version of air pistols, despite allits positive qualities, is considered inconvenient. This is due to the large dimensions of the weapon. The tightness of the pistol, according to fans of pneumatic weapons, is unsatisfactory, since gas leaks were noticed, which negatively affects the firing power.

Packing weapons with accessories

MP-651 pistols are equipped with attached butts, in which the developers provide mirror periscope devices.

Sights in automatic pistols are considered the most popular. The presence of such devices allows you to make adjustments while firing vertically. This is possible by turning the sight screw. For horizontal adjustment of shooting, it is enough to move the rear sight along the guide on the aiming bar.

Of all the options for pneumatic pistols, the devices for MP-651 07 distinguished themselves. Due to the handle (butt and forearm simulating the barrel), this weapon became more like a rifle than a pistol. The weapon is suitable for firing both conventional explosives and lead charges. The air pistol MP-651 KS is designed for an eight-gram gas cartridge, which can be replaced with an analogue with a capacity of 12 g. But for this, it is imperative to acquire an appropriate reinforced valve. Changes in the external design of the weapon did not significantly affect its tactical and technical characteristics, power and accuracy.

Where is it used?

Pistol MP-651 07 KS looks very similar to an air rifle. This isincreased its demand among consumers primarily as a range training and gun training product.

In the production of this model, an aluminum alloy is used for smelting the body, which ensures the lightness of the weapon, its reliability and long service life. Unlike plastic cases, the case of the MP-651 07 KS is quite strong, which is very important when working with it for beginners and inexperienced shooters.

The gun also contains plastic parts. These are overlays for the magazine, aiming bar and handle, made of impact-resistant plastic. The pistol is also suitable for recreational shooting.

Cornet-09 gas balloon

For recreational shooting, you can pick up another version of the MP-651 series. This is a pistol MP-651 09 K. Its performance characteristics do not differ from 07 K.

The source for firing is CO2 gas_{2, which is in a special factory-made eight- or twelve-gram can.}

Shooting is carried out with balls of 4.5 mm caliber, of which 23 pieces can be placed in the pistol magazine. If desired, shooting can be done with bullets having a caliber of 7 mm. To do this, change the magazine in this pneumatic weapon.

This magazine holds eight bullets. When buying an MP-651 09 K air pistol, both magazines come in one set.

The charge ejected from the muzzle channel is capable of speeds up to 120 m/s. In this case, the muzzle energy is notexceeds the limits allowed by law - 7.5 J. The pistol is also equipped with an elongated forearm and a butt that is easy to grip, which makes it look like a shortened rifle. Without the use of a plastic barrel enlarger and buttstock, the MP-651 09 K looks like a regular pistol.

Technical rules for the operation of air guns

In order for the weapon to serve for a long time, it is very important to carry out its maintenance in a timely manner. According to experienced owners of air pistols and lovers of wind weapons, these technical measures should be performed at certain intervals or after a significant number of shots.

It is not recommended to dismantle weapons unless absolutely necessary. Also, you can not remove the spray can from the gun if it is filled with CO_{2. This will significantly reduce the operational life of the sealing elements of the weapon.}

When buying, each weapon model has its own document, as well as instructions, which spell out the disassembly sequence. It is very important to strictly adhere to it.

Assembly in reverse order.

Recommended every time after 500 shots to tighten the fixing screws on the cover and casing. If during firing a charge (bullet or ball) gets stuck in the barrel, then using a ramrod, push the stuck projectile back into the magazine through the barrel bore. If a similar situation occurred with an air pistol equipped with a butt and a forearm for an MP-651 09 KS or 07 KS rifle, then beforehow to start working with a ramrod, the forearm must be removed.

The airgun trigger needs regular lubrication. For this, gun grease RJ TU 38-10 11315-90 is suitable, which is applied to gauze or rags. Lubrication must be carried out every 1 thousand or 2 thousand shots. The barrel of the weapon must be cleaned after firing 500 shots.

About terms of use

Despite the variety and availability of airguns, there are rules for using 7.5 joule pistols:

It is forbidden to bring airguns to public events;
it is forbidden to keep air pistols cocked in populated areas;
we must not allow frivolous handling of weapons, as this may pose a danger to others;
at a distance of 100 m, a shot is dangerous for nearby people, this should be remembered when choosing a direction of fire;
you can not point a loaded pistol at surrounding people and animals, it is allowed to aim only in the direction of the target;
it is forbidden to disassemble a weapon with an inserted cartridge filled with gas;
after the end of shooting, be sure to make sure that the gun is unloaded; if there are bullets in the magazine, you must remove them by removing the magazine;
if it is necessary to stop shooting for a while, you should put the gun on the safety, for this purpose the safety button must be moved to the left relative to the trigger.

Pneumatic weapons and the law

The muzzle energy released when fired from pneumatics is considered an indicator of the power of the weapon. The unit adopted for its measurement is J.

Power is influenced by the speed of the bullet that has flown out of the barrel, its weight. The higher these figures, the higher J.

The legislation of the Russian Federation allows for free sale of pneumatic pistols with power parameters not exceeding 7.5 J. To purchase such samples of pneumatics, you only need a passport, and no permission is needed. It is required for weapons whose power ranges from 7.5 to 25 J.

If the muzzle energy in a pistol or rifle exceeds the allowable parameters, a special permit must be issued to carry and store such weapons. But first you need to register and get a license. Only under this condition, you can safely, without fear of criminal liability, purchase your favorite model of an air pistol or rifle.

The permit to keep and carry weapons exceeding 25 J is valid for five years, after which the owners of such powerful pneumatic models are forced to renew the permit.

When buying an air pistol, all information about its muzzle energy can be found in the certificate or passport. It is contained in the Additional Information section.

Special design solution for the MP-651 KS pistol, its original modern design and affordable priceled to the popularity of weapons among fans of recreational shooting.
