Tuning MP 155 for hunting. History of gun development and design features
DLG Tactical(DLG Tactical) is a Turkish company that began its work in 1988. 30 years ago it was a small family business, and now DLG Tactical is the Turkish leader in weapon tuning. DLG Tactical products are compatible not only with Turkish weapons, but also with the world's most popular brands, including AK.
DLG Tactical's motto is “Brilliant Innovation, Perfect Execution,” that is, “Brilliant Innovation, Perfect Execution.” The company's management repeatedly emphasizes that one of the goals of DLG Tactical is to constantly challenge itself in pursuit of the best result. The company has an experienced team of designers and technologists who work together to achieve impressive achievements. The production enterprise operates on a full cycle - from sketch to casting. When creating accessories, each model goes through several degrees of control.
The products of this company are distinguished by their conciseness, pleasant design and high ergonomic performance. Success is built on the “five pillars”: studying the needs of shooters, ease of use of products, their practicality, reliability and functionality.
DLG Tactical is also one of the first manufacturers to undertake the development and creation of a polymer telescopic stock and pistol grips for the Russian MP-155 self-loading hunting rifle. The kit was presented at the Arms and Hunting 2017 exhibition and has already gained great public interest.
One of DLG Tactical's most popular products is the telescopic stock, available on pre-order. This design is designed to improve the overall ergonomics of the weapon. Allows you to change the length of the stock, increases shooting comfort, weapon controllability and accuracy indicators, and does not cling to ammunition. The telescopic stock is equipped with three slots on the body made for attaching a belt.
The bipod handle with a 4-step side rail is designed to stabilize the behavior of the weapon barrel during shooting, increase overall controllability when firing and reduce the time interval between shots. Available for pre-order.
The tactical bipod handle is equipped with an additional 4-step Pikatinny rail, which allows you to place a laser laser or flashlight on it.
DLG Tactical stocks are presented on our website in an assortment and are available for purchase upon order. You can choose, for example, a stock with a bandoleer, which is a set of pipe and stock with 4 adjustment positions. Has 4 slots for 12 gauge cartridges. It is made of fiberglass reinforced polymer and weighs relatively little - about 450 grams. This telescopic stock allows you to increase the ergonomics of the weapon and change its length according to the desire and need of the shooter.

The versatility of these weapon models opens up vast modification prospects for their owners, and each of them sooner or later begins to improve the Murka. Minimumtuning MP 155which you simply cannot do without - adjusting the working mechanisms. In particular, what is responsible for supplying cartridges and the magazine in general. More labor-intensive, but also yielding resultstuning MP 153- making changes to the trigger mechanism, which in the next generation of guns is already more technologically advanced.
Tuning MP 155 - buy a new stock, magazine extension, choke tubes and you won’t regret it
For those who intend to take it seriouslytuning MP 155 - online storethe best place to purchase the necessary accessories. The catalog makes the selection process easier, and advice from an experienced specialist who knows how to modify a shotgun, rifle orgun,can also be obtained online. Moreover, in order to carry outtuning MP 155 buyThere’s a lot of stuff to come, and as you know, it’s cheaper in bulk. There are only 4 popular areas of modification of an inexpensive pump-action shotgun:
- Brackets with a Weaver rail for installing optics and other accessories, in particular flashlights;
- Magazine extensions;
- Butts;
- Choke tubes.

Tuning the MP 153 shotgun - what is important to improve first
More oftenMP 153 shotgun tuning, as well as the next modification, includes replacing the butt or installing a pistol grip. The ability to adjust the length to suit the needs of a particular shooter increases the comfort of the grip and makes it more stable, which leads to increased shooting accuracy. Suchtuning MP 153 online storeoffers a wide range, so choosing the optimal configuration option will not be difficult. Elastic polymer butt pads, a compartment for storing batteries and other spare parts, as well as other nuances, for example, the number and location of swivels - important nuances that need to be paid attention to as well as the design as a whole and the features of its coating. If we talk aboutMP 153 tuning - buttnot the only thing that is most often replaced. The second most popular upgrade is extending the magazine. The most popular are lightweight tubes with a washer and cap to simplify installation and increase reliability. Used like thisMP 155 tuning for practical shooting, as well as for hunting.
A separate category of improvements is choke constrictions. The ideal solution to carry outtuning MP-155 internetcalls multichokes. A similar nozzle can be used as a standard constriction from a cylinder to a full choke, and intermediate options, depending on its configuration. At best, something like thisMP tuning, will also perform the functions of a DTK, which means recoil and toss will be reduced.
For those who seriously decided to doMP-155 tuning, shopMost likely you will have to visit more than once, because one of the most important advantages of the gun is the ability to easily return to the basic configuration.
Part I
History of gun development and design features
In all the years of production of the MP-153, only the lazy have not written about this Izhevsk self-loading machine. As usual, the gun was both praised and criticized, not forgetting to compare it with such old Soviet systems as MTs-21-12 and TOZ-87. Of course, there were comparisons with imported semi-automatic machines. And this is where an extremely careful and balanced assessment is required. After all, it is no longer a secret that imported weapons do not always objectively correspond to the manufacturer’s advertising statements, while domestic weapons naturally occupy far from the last positions on the Russian market.
The message about the test firing of 50 thousand rounds from one copy of the MP-153, carried out by Italian dealers of the Izhevsk semi-automatic device, has almost been forgotten. All the advantages and disadvantages of this gun, with which everyone hunts, have long been “worn out”. I saw “Murka” in all regions of the country, from the Caucasus to the Southern Kuriles, in the hands of villagers and heads of municipalities (the mayor of Aleksandrovsk-Sakhalinsky, Vladimir Fedorovich Nikitin, from 1999 to this day he hunts only with his personal MP-153 and rightly considers it an excellent weapon).
The fact remains that the gun, produced in 600,000 copies, continues to sell well in the domestic and foreign markets. And since last year, a modified lightweight version of the people’s favorite “Murka” - MP-155 - has gone into production.
To obtain information from the original source, I managed to contact one of the developers of the gun, Alexander Igorevich Kalugin, now holding the position of Deputy Chief Designer of IZHMEKH, who told a lot of interesting things about the history of the gun and its design features. Some of this information appeared on the pages of magazines, but the reader will learn about much of it for the first time.
From MP-151 to MP-153 - How it all began
A. Kalugin says:“The first work on smoothbore self-loading at IZHMEKH began on its own initiative at the end of 1996. Konstantin Evseev spent the evenings working on a possible design for a self-loading shotgun based on the IZH-81 pump-action shotgun that was then being produced. When almost all the drawings were ready, another inventor approached the plant with a proposal to start producing a self-loading gun of his design, also converted from IZH-81. The drawings were transferred to the design department: to evaluate the design, manufacturability and manufacturing feasibility. It was a 12/70 caliber gun. Then Konstantin showed his own developments to the department management. It was decided to conduct comparative tests, according to the results of which preference was given to Evseev’s design.
Konstantin Vladimirovich Evseev got a job at the plant after defending his diploma project in early 1996, and towards the end of the year I came to the plant for pre-graduation internship. I was asked to combine my studies with work in the department. We worked in neighboring groups and stayed late in the evenings after work, when almost no one was there. I was developing a reduced horizontal profile for my thesis project, and Kostya was working on self-charging. We often looked at what each of us was doing, discussed technical solutions and somehow quickly became friends. It is possible that when the decision was made to put Konstantin’s development into production and he was asked who he would like to see as an assistant, he named me.
We were transferred to the development group of Vitaly Petrovich Votyakov and were tasked with testing the design for production. The gun received the factory designation MP-151. The development was supervised by the deputy. chief designer for R&D Vladimir Petrovich Budanov and chief designer Alexander Usherovich Dorf himself. But we must thank them for the fact that Konstantin and I were given greater independence. As a result, preparations for production were carried out and they even managed to produce the first batch of MP-151 shotguns.
MP-153
In 1999, when preparations for production of the MP-151 were almost completed, an American dealer, Keith Burkrant, came to the plant. He was shown a new self-loading device. The American said that the future in the market of self-loading shotguns belongs to supermagnums of 12/89 caliber and it would be nice if we made such a shotgun instead of the MP-151. By that time, we already knew that the IZH-81 base would not allow us to create a durable gun chambered for the “usual” Magnum cartridge - 12/76, but here it is 12/89.
Konstantin proposed to completely redesign the design. And the management decided to take a risk. While preparations for the production of the MP-151 were in full swing, a new self-loading system was developed in parallel. The new design was tested just as preparation for production of the MP-151 was completed. No more than 100 copies of this model were produced. first qualifying batch.
Since the new gun was superior to the MP-151 in many characteristics, it was decided to prepare the production of a new model under the factory designation MP-153. (The management did not take too many risks, entrusting the parallel development of a self-loading gun to more experienced designers with extensive experience in the department - they developed their version under the symbol MP-152, but did not keep up with the young designers who were ready to stay after working hours and use computers instead of drawing boards) .
At the beginning of 2000, production of the MP-153 shotgun was prepared. Only 14 months passed from the start of its development (the first line on paper) to the release of the first gun. I note that before this, the plant had no experience in developing self-loading rifles, except for individual attempts that were made by designers no longer working in the department. This was Russia’s first self-loading gun of 12/89 caliber, and it worked reliably on the entire range of cartridges - from 12/70 to 12/89.
During development, we encountered various problems. For example, one of them is the lack of 12/89 cartridges in the country. The customer brought cartridges made in Italy. The quality of the cartridges left much to be desired. They simply did not fit into the chamber, were deformed and had pellet markings on the outer surface, and we were given the task that the gun should work with any cartridges.
With these cartridges, we encountered bouncing of the tray when firing due to recoil. Initially, the design did not have a holder and we did not quite understand why the Remington had a similar part near the tray. The gun worked similarly to a pump-action gun - the interceptor was released by the frame after some movement and the cartridge came out of the magazine onto the tray. But by the time the frame released the interceptor, the tray had time to jump and block the path of the cartridge. And then the shot occurs, the cartridge case flies out, the bolt comes forward, you press the trigger, but there is no shot. The cartridge did not remain in the magazine, and the chamber was empty. There was no high-speed shooting, and we did a lot of testing and testing before we found the reason. Moreover, this delay was floating, sometimes it was there, sometimes it wasn’t. And again, almost parallel to the beginning of production, the design is changed and a holder is introduced. At the same time, it was possible to solve the problem of safely unloading a gun.
On the Italian shotguns we have seen, there is a similar part that releases the interceptor when the hammer is released. Therefore, in order to unload the gun, you need to pull the trigger, pull the bolt twice (feed a cartridge into the chamber and then deflect it) and pull the trigger again. At the same time, more than once I myself observed random shots.
You can unload the gun by simply pressing the interceptor, but this is very inconvenient. On the MP-153, you can put the gun on safety, and, alternating between pressing the holder and jerking the bolt, unload the weapon without touching the trigger.
Recognized abroad
By the start of production of the MP-153 shotgun (2000), there were almost no foreign analogues. And our gun has received great recognition in the world - it has been awarded several diplomas, including being recognized as the gun of the year in the USA. It has been repeatedly subjected to various tests. For example - in Italy. Many people have heard that 50,000 rounds were fired there. The PRIMA ARMI company, which promotes the Baikal weapon in Italy, first conducted its tests on a small scale (about 10 shots), and then invited weapons journalists writing in Italy and manufacturers of sporting cartridges to conduct large tests of the gun. They took the first gun they came across from the purchased batch and started shooting at a very fast pace.
Only two comments were noted. First: the barrel became so hot during shooting that the solder flowed out and they removed the bar so that it would not hit the shooter if it was disconnected. Second: it is possible that the spring of the interceptor button was broken during cleaning and improper assembly. By the way, there is a video on YouTube of one Canadian user testing the MP-153 by throwing mud at it and bathing it in an ice hole.
In 2001-2002, many imported new products appeared: self-loading 12\89 caliber. These were good guns, but they did not show significant superiority over the MP-153 either in reliability, durability, or any performance characteristics.
In 2003, a separate production support group was created under my leadership. In total, from 2000 to 2012. About 600 thousand MP-153 rifles were produced, about half of which were exported.
Since 2008, the next generation of imported self-loading shotguns of 12/89 caliber began to appear. The main advantage of the new self-loaders is weight reduction. We also began to lose to the approaching Turks in the segment of 12/76 caliber shotguns, since due to the unification of 12/89 and 12/76 caliber shotguns, a 12/76 caliber shotgun had more weight than its competitors.
Therefore, at the end of 2010, it was decided to speed up work on the development of a new self-loading rifle to replace the MP-153. The main burden of development fell on Marat Shamilevich Sabirzyanov, who replaced me as group leader. Yesterday's students Vladimir Preobrazhentsev and Ekaterina Shishkina helped him. Although they did not come out of nowhere (in our group, with my participation, they had worked out some alternative designs before), they had to practically rearrange some components from scratch, working out a new design for the current production. The new gun was designated MP-155.

Advantages and disadvantages of MP-153
The main and almost undisputed advantage of the MP-153 is reliability. We received many letters (including from abroad) from ordinary consumers asking why we are promoting such a good gun so poorly. Many foreign manufacturers either add some kind of rings to their guns (additionally installed on the gun when using different cartridges), or make reversible pistons, or develop automatically adjustable recoil speeds for the system to increase reliability of operation with different cartridges.
However, there is such a wide variety of cartridges in use that it is very difficult to make a system that works with any of them. At the time of development of the MP-153, Remington and Browning had some of the best self-regulating systems. The ratio of the rollback speeds of moving parts when using 12\70 and 12\76 cartridges was about 1/2. At the same time, the systems that were at our disposal did not provide for the use of 12/89 cartridges. We managed to develop a unit that provided a speed ratio of 1/1.6 and only on 12/89 cartridges produced a ratio of 1/1.8, which reduced the load on parts and actually increased the durability of the product.
I already spoke about another plus - safety - a little earlier (about unloading a gun). However, the security measures do not end there. For example, in the trigger mechanism, the disconnector additionally plays the role of a fuse when the bolt is not completely locked, which is not the case on some guns (Turkish production).
Some consumers consider this to be an advantage of the “Turks”: you can pull the trigger without impact, by moving the frame a little back, press the trigger and, moving the frame forward, release it without impact in the extreme forward position. However, when shooting, an involuntary repeated pressing of the trigger may occur (one of the main causes of double-barreled single-trigger shotguns) when the finger lags behind the hook at the moment of recoil and presses it again after the shot. This can lead either to a double shot (the gun seems to fire in automatic mode, although this is not the case), or to the impossibility of a second shot, since the trigger is already pulled. Occasionally, consumers encountered this on the MP-153 due to improper operation of the disconnector (the reason was the bending of the sear pusher or its incorrect installation).
Also, one of the advantages at that time was the use of two cartridge case hooks in the MP-153: an ejector and a extractor. Many products at that time had one ejector. And for a smoothbore shotgun cartridge case that does not have a groove with a rim that has a certain angle, the probability of jumping off the ejector hook is much higher than for any rifled cartridge.
While testing the reliability of the MP-153 shotgun, we encountered cartridges (imported) in which the rim was blown and the angle increased to almost 30 degrees. None of the imported samples at our disposal worked for them. The number of delays due to non-reflection of cartridges reached 10 percent or more (on some samples it reached 50). The use of two hooks made it possible to reduce the number of delays to 1-2 cases per hundred shots with such ugly cartridges.
One of the advantages of the MP-153 is the ability to extend the magazine by replacing the barrel nut. 12-13 years ago, few products had this capability. This idea belonged to the then technologist of the experimental workshop, Alexander Vitalievich Kazakov. Together with Konstantin Vladimirovich Evseev, he received a certificate for a utility model.
One, sometimes controversial, decision was to place the recoil spring on the magazine tube, although virtually all other manufacturers had it in the stock. But this allowed us to offer the consumer the option of using a pistol grip or a folding stock. Konstantin and I did not see any obvious disadvantages to this at the time of development. We considered the dimensions of the forend to be a disadvantage, but production capabilities did not allow us to produce the forend as on the prototypes. During technological testing, we were asked to increase manufacturing tolerances and wall thicknesses.
One of the disadvantages appeared during mastering, when qualification tests began. Konstantin was then tasked with developing a system based on the MP-153 rifle that could operate in self-loading mode when using cartridges with low energy (rubber bullets or buckshot, for example), which received the designation MP-154. But then it was practically not produced by the enterprise, due to the lack of significant orders, with the production fully loaded with the MP-153 gun.
And it fell on me to work on and put the gun into production. When conducting testing, we wanted to make the gun work with as few cleanings as possible. And on some guns, after 150-200 shots, the trigger suddenly began to disappear (you press the trigger, but there is no shot). Messages began to come from the workshop that some guns refused to fire after several shots; it was necessary to press the trigger repeatedly for a shot to fire. The cause turned out to be powder particles getting into the gun box and into the trigger mechanism. A particle of gunpowder fell between the trigger and the tubular axis, on which it rested in the rearmost position, and the gap between the sear pusher and the sear disappeared. As a result, their mutual interlock did not occur after the hook was released after the shot. I had to increase the gap by introducing a discharge on the trigger, but this immediately increased the trigger travel, which some consumers later pointed out to us.
MP-155
In 2002-2003, new self-loading devices appeared in the world, having a mass of 3.2...3.4 kg. By 2004, a big disadvantage was the decision to unify the boxes of shotguns in calibers 12/76 and 12/89, as a result of which the weight of the MP-153 shotgun began to reach 3.6, and sometimes up to 3.7 kg. Some work has been done to reduce the weight of the product. The design did not change, with the exception of certain parts, the weight was reduced to 3.45...3.5 kg. But by 2010 this was not enough. A new generation of self-loading guns has appeared, from almost all the world's manufacturers of self-loading shotguns (Maxus, Vinci, etc.).
The new self-loading MP-155 was primarily created as a replacement for the MP-153. Neither reliability nor durability should be compromised. The main goal was weight loss. This has been achieved. The weight of the new product with a barrel length of 710 mm does not exceed 3.15 kg.
The new product has eliminated some of the shortcomings of the MP-153. The trigger mechanism has been redesigned. The trigger travel has been reduced. The shape of the holder has been changed. There were two complaints about it on the MP-153: in winter, pressing a button with a small area caused pain in the finger, and even a small amount of protrusion did not protect against accidental pressing of the button by foreign objects while moving. The new part was recessed behind the trigger guard to eliminate accidental snags when something slides along the guard, and the area of contact with the finger itself was increased due to the width of the part.
Two new recoil pads were developed for the new lightweight gun, reducing the impact of recoil on the shooter. They are interchangeable and, in addition, allow you to adjust the length of the butt to suit you. To increase the possibility of adjusting the gun to the shooter, the gun is equipped with spacers that allow you to change the angle of the buttstock vertically and horizontally.
One of the big disadvantages of our guns is the use of tin-lead solders for soldering strips at low temperatures. Many complained about cases of destruction of the soldered joints of the strap with the barrel, which is especially important for self-loading. Therefore, on the new gun, it was decided to solder the bar using silver-containing solder, which can withstand higher loads while simultaneously heating the barrel during shooting.
It’s too early to talk about the disadvantages of the new gun, time will tell. What comes to light now, we try to eliminate promptly. Did we succeed with the new gun? I think this can be judged no earlier than November-December of this year...”
Tuning MP-153 - User opinion
When writing this article, the initial goal was simply to offer readers a few interesting facts from the original source - one of the developers of the MP-153. But in the process, the story of Moscow resident Alexander Ivanov was added to the material, who literally “on his knees” subjected the MP-153 to interesting modifications in several stages.
A. Ivanov says: “I don’t think I’ll reveal the secret that the MP-153 is a fairly versatile and universal gun. One of the sides of this versatility is the ability to modify the gun to suit your tasks through the modernization of individual, non-main parts of the weapon. To understand the essence, I would divide the tuning (setting) of any weapon into three main categories:
Finishing, (or, as it is also called, “peeling”) - elimination of factory and design defects. This includes adjusting mechanisms, removing burrs and other little things.
The Izhevsk Mechanical Plant has long proven itself to be the best, producing high-quality and very durable products. One of the company’s developments was the MP-155 hunting rifle, which took the predecessor of this model, the MP-153, as a base. Next we will talk about all aspects of the gun in more detail.
Gun design
The appearance of the gun is very presentable, although it does not claim to be a collector's item. First of all, the ornate design elements are striking: intricate butt plates and butt plates, notches on the forend, triangular shape of the safety button, and so on. In general, manufacturers have moved away from brevity and simplicity to more luxurious notes. The weight of the gun is also pleasing, it is a measly 3.15 kg. Of course, among imported models there are also lighter ones, but the price also makes itself felt, exceeding the similar indicators of domestic guns by 15-20%. At this point the attention of any hunter will fall on the MP-155. Tuning, by the way, is an integral part of all guns, which allows you to get rid of factory defects or improve the characteristics of the gun itself. If we talk about design, you can use applications that will make your purchase look more elegant and more impressive.
Fans of the MP line endlessly argue about which concept is better: the one that was in the MP-153, where the gun was intended more for “tight” shooting, or the MP-155, which already easily allows for running hunting. There are so many people - so many opinions. If we talk about the characteristics of the MP-155, then here too you can observe some differences between the 155 and the 153. Of course, here too the gun became a little smaller, where the length varies from 610 to 750 mm, depending on various modifications and tuning elements. Weight ranges from 3.15 to 3.25 kg.
MP-155: tuning in winter
Winter hunting is extremely important for any hunter, but the animal may be frightened by the sight of a gun that stands out against the general background with a dark color. Of course, you can use the above-mentioned applications, but their cost is quite high, which is a good reason for Russian citizens. In this case, you can paint it white, but such a radical move does not justify itself, because winter is a seasonal matter, and no one wants to repaint the gun every time. And here folk methods can come to the rescue, which we will talk about in more detail.
If you decide to use the MP-155 shotgun during winter hunting, you can use ordinary women's tights as camouflage, which do an excellent job of camouflage. This is done as follows: we take a hot nail, with which we make small holes in the wardrobe element, after which we fix them on the gun using white cloth or adhesive tape. The method is short-lived, but will cost a measly 100-150 rubles.
If you don’t like this approach, you can use a gauze medical bandage. There is a significant drawback of this method - the bandages quickly unravel on the thread, and also cling to any surface when moving. In this case, elastic bandages will come to the rescue. Finally, if this is not to your taste, white mounting tape, which is sold in any hardware store, will do an excellent job with such a non-trivial task.
Gun barrel
This element of the gun is made of B95 brand, which is famous for its durability and quality. In addition, most shotgun manufacturers use this particular material, so Russian manufacturers are in no way behind their foreign colleagues.
In order to reduce the weight of the barrel, the engineers decided to modify the sighting bar, which became arched. In previous versions, as you remember, it was soldered along the entire length of the barrel. Of course, the weight was reduced, but all this created problems with attaching the bar itself, which must be soldered with silver-containing solder. Innovation has long been asking for implementation, because the old forms clearly hindered progress in general. The width of the sighting bar has become slightly higher - 6.8 mm in the MP-155 shotgun versus 5.9 mm in the 153.
Speaking of attaching the bar. At first glance, it seems that it is tightly soldered, but upon closer inspection you will notice 7 pins, with the help of which this element is attached to the barrel. The quality of guilloche is somewhat inferior to that of 153.
Types of boxes
Depending on the caliber of cartridges, there are 2 types of receivers for our hero. There are also 2 calibers, as you might guess: 12x76 and 12x89. The slots for the collimator located on top were a long-awaited surprise. To slightly increase versatility, the top of the box acquired a flat, which made it possible to reduce the required height of the bracket supports. Separate grooves were also waiting to be combined into a single part. At the same time, the guilloche disappeared, which significantly worsened the ease of aiming. Unlike the MP-153 box, here it has also become shorter.
Gun body kits
Nowadays there are many body kits that can be installed on the MP-155. Tuning your gun will allow you to aim better, help you in the dark, or improve the quality of your shooting. Now we will talk about installing the flashlight and bracket.
As for the first, collimators are open and closed. In turn, each of them has its own advantages and disadvantages. A closed one, for example, is better protected from mechanical damage, while an open one has better compactness, a presentable appearance, and a greater overview than its competitor. Be that as it may, it’s up to the owner of the MP-155 gun to decide. The price of collimators varies, starting at 4,000 rubles and reaching 100 thousand. Such a wide variation is characterized by quality, brand and depth of various settings.
A bracket can also become an important weapon attachment, which allows you to maximize the capabilities of the MP-155 shotgun. The price is low, amounting to 1300-2000 rubles. This applies to products from a Russian manufacturer. Imported analogues will cost slightly more. In our hero, the bracket will allow you to hold a flashlight, which will be an excellent help to any hunter. Really high-quality under-barrel flashlights start at 5,000 rubles. Continuing to talk about MP-155 attachments, do not forget about them, which are gaining more and more popularity among hunters. The pleasure, of course, is not cheap, because a set can cost 75 thousand rubles or more. Nevertheless, for this amount the owner receives excellent optics with a certain magnification, as well as many functions, including focusing, one-shot shooting and many others. Finally, having decided to 100% apply tuning to the MP-155, you can change the stock and install a tactical grip.
Gate
The firing pin and bolt were also reduced in size, which contributed to the shortening of the rear part of the bolt frame. This leads to a fairly logical conclusion that the firing pin from its predecessor will not work. With all the above innovations, the shutter stroke length remained at the same level, equal to 102-105 mm. The bolt handle itself was left interchangeable. It is worth noting that the engineers introduced longitudinal valleys, which serve more of a decorative function rather than a practical one. On them you can see the mark and number of the gun.
Speaking of appearance, the MP-155's bolt is not very different from its familiar predecessor, but several elements have been redesigned. First of all, the eye falls on the facilitating selections, which do not greatly affect the survivability of the gun. The extractor has also undergone some changes, becoming axleless.
Gas engine
When compared with the MP-153, we can note a deeply modified unit, where the gas discharge system was moved from the barrel to the piston. The decision is quite correct, because the total mass of metal in such situations works much better and optimally. In addition, cleaning the unit, as well as adjusting or replacing it, becomes much easier. Some concerns may only cause a significant reduction in the soldering area to the gas chamber barrel, which is likely to greatly affect the durability of the parts. In general, a very controversial decision.
As for the choke tubes and the magazine nut, they remained the same, which is why the handguard from the 153rd will be like original on the 155th. The trigger mechanism (trigger mechanism) has become a little lighter, and the shape and location have changed quite noticeably. At the same time, they did not touch it, leaving everything in its place. The trigger pull is 1.1 mm and 2 kg.
The magazine cutter deserves a special mention and is an excellent apprenticeship even for those who have never used one before. The butt plate has also been somewhat updated, becoming thicker and sporting a complex combination (plastic-rubber).
Practice
For avid hunters and gun lovers, the shooting experience will remain the most vivid. Of course, shooting is not very different among the “classmates” of the 155th, but in comparison with its predecessor, fatigue is felt less. This is especially true for long runs or throwing the MP-155. Tuning, a photo of which you can see in this article, slightly increases the weight through attachments, but it will not exceed 3.7 kg (charged version). Delays are extremely rare, and you won’t encounter frequent misfires here. It will be quite easy for a beginner to get used to this weapon, however, as with other semi-automatic weapons, you will have to practice “automatic” shooting a little. It just so happens that “green” hunters stop shooting after 2-3 shots, although the target is still within their reach. Actually, training with the 155 is very simple: we place several plates or bottles on the field (preferably scattered), and then fire with transfer fire until the cartridges in the magazine run out. The main thing is practice.
Shotgun MP-155 - owner reviews
In general, users note many advantages of this gun. As for the advantages, most hunters liked the relatively light weight of the gun, as well as its high-quality assembly, which does not allow the 155 to break after the first shooting. Finally, the ability to attach the gun with numerous attachments completes the overall positive impression.
Of course, the MP-155 gun was not without some defects. Reviews from owners note a weak interceptor, which is very prone to bending around the axis. Sometimes there are misfires, as well as misalignment of the rings in the barrel. Finally, cases of earring axis falling out are quite common. Otherwise, it’s a completely excellent gun, which competes on an equal footing with foreign models.
Finally
As a result, we received a very good gun that corresponds to its price category. As for a domestic manufacturer, it is of high quality and convenient, and can also be upgraded quite well, which will definitely appeal to tuning lovers. We can recommend it to both avid hunters and beginners. And the price will please you, which is in the range of 25-30 thousand rubles, depending on the configuration.
