Review of characteristics of the MP-512 air rifle, advice on selection

This article is devoted to one of the most popular domestic rifles - MP-512 produced by Izhmekh. For the letter abbreviation, the arrows gave it the nickname “Murka”, under which the product became widely known. And although several new models later appeared in the series, “Murka” refers only to the 512th model.

So, what is remarkable about the spring-piston single-shot rifle IZH MP-512? First of all, the cost, which pleasantly surprises even experienced pneumatic experts. Today, the rifle is sold at a price of 3,500–4,000 rubles, which is one of the best offers on the market. That is why more than half of the shooters started their journey with the MP-512 “Murka” or, at least, shot from it in one of the entertainment shooting ranges.

• muzzle energy - no more than 7 J;
• initial bullet speed - 150 m/s;
• length - 1050 mm (with a barrel length of 450 mm);
• caliber - 4.5 mm;
• weight - about 2.8 kg.

Rifles are made from high quality materials. Depending on the modification, the following is used:

• tree;

• steel.

The combination of different materials provides an attractive appearance of the weapon and a pleasant tactile sensation. The design of the rifle is ergonomic and provides ease of use. The technical characteristics of the model deserve special attention:

The model will be an excellent visual aid for novice shooters. “Vozdushka” has become widespread in hardball clubs.

The air rifle variant under consideration has become a replacement for the popular IZH-38 model, which can be found in almost any park shooting range in Russia.

Advantages and disadvantages

The main advantages of the MP-512 rifle are its affordable cost and wide potential for improving the design. “Vozdushki” have been produced for more than 20 years, so on specialized forums you can find a lot of information on improving the model. Other advantages of pneumatics include:

• high build quality;
• wide range of models;
• versatility of use;
• practicality, long service life;
• strength, careful thought out of every detail;
• ease of maintenance and care;
• comfortable butt;
• high accuracy of shots;
• possibility of adding a powerful optical sight to the design.

You can repair an air rifle from a domestic manufacturer MP-512 almost on your knees. The design is as simple as possible, so there is nothing to break in it. You can always sell unnecessary weapons even after an unsuccessful upgrade.

The “air” also has some disadvantages. The design needs careful fine-tuning, which will require appropriate experience. The new stock, consisting of 5 parts, negatively affects the accuracy of the rifle. To solve the problem, adjustments must be made.

If modification 512 cannot be improved with your own hands, it is better to immediately purchase a more expensive rifle that will meet the user’s requirements.

Upgrade of the MP-512 "Murka" rifle

This model is very convenient for upgrade. Like plasticine, owners can mold it into a rifle with almost any characteristics for hunting, hardball and their own pleasure.

The first improvement in line is replacing the spring with a more powerful one. For example, installing a Gamo Hunter cut spring dramatically increases muzzle velocity. The second standard upgrade of the IZH MP-512 is the mounting of an optical sight, the choice of which depends on the needs and financial capabilities of the buyer.

Popular modifications of “Murka” also include:

• cylinder grinding;
• production of weighting material and telescopic guides;
• USM wall boring;
• installation of cuffs, muzzles and many others.

Device and principle of operation

The spring-piston rifle from the Izhevsk plant has a fairly simple design. The main role is given to the main elements:

1. Butt (stock). The part with which the pneumatic is held in the hands. It is made from wood or plastic.
2. Trunk. A projectile passes along the rifling of this element, gaining speed. The accuracy of the rifle depends on the characteristics of the part.
3. Trigger. After clicking on it, a shot occurs.
4. Fuse. Prevents accidental actuation of the trigger, can be manual or automatic.
5. Front sight. Present on every rifle, it allows you to shoot accurately at the target.
6. Rear sight. This is not always installed, however, the absence of an element can be compensated for by purchasing an optical sight.

The principle of operation of “Murka” is quite simple. Breaking the barrel while loading is done in one quick, sharp movement. The pneumatic mechanism is cocked smoothly until a characteristic click appears. Any bullets can be selected, the main thing is that they fit the 4.5 mm caliber. For stock versions of rifles, shells are selected whose weight does not exceed 0.75 g.

When locking the barrel, a fairly strong push is felt, the parts are fastened tightly, without play. Immediately after the piston is cocked, the fuse is automatically turned on. When turned off, the lever located under the trigger guard is recessed into the stock. After completing the above steps, shooting begins. Without firing a shot, it is impossible to decock the MP-512 rifle.

If necessary, the position of the rear sight is adjusted. You can adjust this component in the horizontal and vertical plane. The front sight mounted on the bracket is in a protective casing and cannot be adjusted.

Reviews

Alexander Seminozhenko, 42 years old, village. Rainbow

The purchase of the rifle was caused by the children's interest in shooting sports. This rifle was the first in the family, and probably the most beloved. Now there is something to compare with, fortunately there are already more powerful and expensive air blowers. The first thing to note is the unpretentiousness and endurance of the rifle. Sometimes the firing reached 300 shots in one day. The power did not decrease, the bullet speed dropped, but only slightly. We usually shoot at 10 meters from three positions, children are 12 and 14 years old. After 2 weeks they managed without my help, broke them themselves and charged them without any problems. We do zeroing once every 2 months, this is enough to shoot normally at standard targets. I recommend that everyone starting out buy the MP 512.

Modifications

Izhevsk Mechanical Plant has been producing the famous “Murka” since 1998. The manufacturer did not stop at the classic model, but offered the consumer improved modifications:

1. MR-212-08. Unlike the basic model, it has a bed made of good wood, most often birch. Thanks to this, the rifle has become much more comfortable to hold, however, the weight has increased. The trigger guard looks like a separate element.
2. MP-512-14 "Elegant". Experts consider this option the most successful. The forend and butt are made of reliable wood, complemented with polymer inclusions. The trigger guard has become an independent monolithic component. The design is equipped with a rubber shock absorber backplate. Thanks to the use of an additional weight, the muzzle energy increased to 7.5 J.
3. MP-512-11 “Updated design”. The main differences of the model are an updated stock made of polymer materials, a change in the shape of the coupling, and the use of a modified muzzle and weighting material. Another important feature of the rifle is the installation of a longer spring.
4. MP-512-22. The model is similar to the previous version. It is distinguished by a relatively weak spring and the absence of a bored back. However, the latter is sometimes installed in this modification.
5. MP-512-24. The main elements will be the same as those of model 22. The main difference is the use of a combination of wood and plastic when creating the butt. Experts say that the stock sometimes bursts during use.
6. MP-512-26. Exactly repeats modifications 22, 24. Due to user complaints, the stock is made entirely of wood.
7. MP-512-36. The simplest modification, has no global changes. The weapon is the same as Model 11, except for the color of the stock and rubber inserts.
8. MP-512S. The weakest model, which has a short shot range, muzzle energy of 3 J. This option is allowed for use without special permission, and is often purchased for a subsequent upgrade.
9. MP-512M. They belong to the Magnum class, the muzzle energy is 25 J, which makes the modification suitable for hunting.

A suitable modification of the rifle is selected taking into account the cost, purpose of use, and the possibility of improvement. First you need to study the features and characteristics of each option.

Recommendations for selection, operation and care

When choosing a sporting type of weapon, you need to carefully inspect the barrel and check the quality of the muzzle chamfer. They examine the breech with a flashlight and look inside the rifle. It is important to clarify whether the design is straight and how evenly located the seats for the sights are. Compliance with two important rules will help increase the service life of the “air”:

• You cannot make empty shots, without shells;
• It is not recommended to use all kinds of objects that are not intended for use in air weapons instead of bullets.

You should not immediately fire your newly acquired weapon. Otherwise, scratches may appear on the cylinder due to the presence of factory debris. Often, failure to comply with the manufacturer's instructions results in cuff failure.

First of all, the new rifle must be disassembled and cleaned of grease. A new composition is applied to the main elements - piston, spring - without touching the cuff. After assembly, the design will fully comply with the parameters outlined by the manufacturer.

The MP-512 is considered one of the best rifles common in Russia. The weapon is characterized by increased accuracy of shots, is equipped with a safety lock, and is affordable. Craftsmen often upgrade the model, increasing the functionality of a simple “air”.
