Ultralight machine gun FN Evolys. Assault rifle competitor

73

May 6, the famous Belgian manufacturer of small arms weapons FN Herstal (Fabrique Nationale) in the format of a video presentation showed the whole world a new development - an ultralight machine gun named Evolys. FN Evolys - a model of a machine gun with a belt feed system. They are already talking about the new product that it claims to be a new class in the arms world.


Such conversations did not appear from scratch. The novelty of the Belgian arms industry is distinguished by its small mass and compact size, which makes weapons akin to assault rifles. At the same time, FN Evolys retained the characteristics of full-fledged machine guns. As part of the May presentation, the public was presented with two models for the most popular cartridges today: 5,56x45 and 7,62x51 mm NATO.

The full debut of the novelty at the exhibition should take place in London from September 14 to 17, 2021. On these dates, the international arms fair DSEI (Defense Security and Equipment International) will be held in the capital of Great Britain. You can see the new ultralight machine gun live at the FN Herstal stand in the Belgian pavilion.

Presented features of FN Evolys machine guns


The emphasis of the presentation of new ultralight machine guns was made on the fact that this is practically a new class of small arms. The new items combine the capabilities of assault rifles and full-fledged machine guns with a belt-fed system. According to Yves Roskam, development manager at FN Herstal, the new light machine gun is built around a concept that assumes combat operations in dense urban areas are the rule, not the exception.


According to Yves Roskam, comprehending this fact requires the creation of mobile, rapid-fire weapon models that would provide an individual combat unit with the maximum level of firepower. According to him, the new Belgian machine gun will be equally effective in combat at a minimum dagger distance, and for aimed fire or suppression fire.

The design of the FN Evolys machine guns is based on a scheme for removing powder gases from the barrel. This is an ultralight model with a short stroke gas piston and an open breech. It is noteworthy that the machine guns are built with the borrowing of a large number of parts and assemblies from other samples of small arms from the Fabrique Nationale company. For example, a telescopic stock that can be adjusted in reach and height, sights and a receiver, similar to those found on the FN SCAR-H assault rifle.

The well-thought-out ergonomics of the FN Evolys machine guns, along with the small mass of the models, allow effective fire from almost any position. In addition, Evolys machine guns received a hydraulic recoil brake, which reduces recoil when firing and provides the weapon with a constant rate of fire.

All this allows you to combine a high rate of fire with very good accuracy. In the demo video, the shooter from his hands in a standing position fires from an FN Evolys machine gun chambered for 5,56x45 mm, calmly shooting a tape for 200 rounds. For shooting from a machine gun while lying on it, there are bipods, which are prudently made of lightweight composite materials.


The model has a two-way switch of fire modes, which allows the fighter to choose either firing single cartridges or a fully automatic mode of operation. The features of the model include the lateral ammunition supply mechanism patented by FN Herstal. The presence of such a unit allowed the designers to install a full-fledged Picatinny rail over the receiver on the FN Evolys machine gun.

Much attention was paid to the ergonomics of the model. As with most modern western small arms, the Evolys can be controlled with only one hand. At the same time, the controls are designed for the use of weapons by both right-handers and left-handers.

Technical characteristics of machine guns FN Evolys


FN Herstal has published the technical characteristics of the new machine guns on its official website. The model for the low-pulse 5.56x45 mm NATO cartridge seems to be the most compact and is very lightweight for belt-fed models. The declared weight of the machine gun is approximately 5,5 kg. For comparison: FN Minimi under the same cartridge or its American counterpart M249 SAW weigh about 6,5 - 6,85 kg without cartridges.

The overall characteristics of the FN Evolys ultralight machine gun are as follows: the maximum length with a fully extended telescopic butt is 950 mm, with a fully folded butt - 850 mm. Barrel length 14 inches - 355 mm. Machine gun width - 133 mm.


Two modes of firing are available for the machine gunner: semi-automatic and fully automatic. At the same time, the practical rate of fire is 750 rounds per minute. The machine gun is powered by belts for 100 or 200 rounds from a special box-bag, similar to that used on the FN MINIMI machine guns. The maximum effective firing range of the 5,56 mm model is 800 meters.

The FN Evolys ultralight machine gun chambered for 7,62x51 mm NATO is more massive. It weighs 6,2 kg, but it is still lighter than the smaller caliber FN MINIMI models, and almost two kilograms less than the 7,62 mm MINIMI. The maximum length of this model is 1025 mm, the shortest is 925 mm. Barrel length - 406 mm, machine gun width - 135 mm.

Power supply of this model is carried out by belts, designed for 50 rounds. These are still tapes from FN MINIMI. It is possible both a simple feed of belts and from a fabric box, the use of which also reduces the weight of the model. The maximum effective range of a machine gun chambered for 7,62 mm is 1000 meters.

Comparison with Russian machine guns


The main advantages of the new Belgian machine guns are their compact size and low weight. In this regard, they successfully compete with all modern machine guns. For example: the Russian single machine gun "Pecheneg" in the bipod version weighs at least 8,2 kg with a length of 1155 mm.

On the other hand, these are models of automatic weapons, sharpened for different combat missions. The Russian single machine gun has a longer barrel - 658 mm and a greater effective firing range - 1500 meters. But naturally, it is less suited for operations in dense urban buildings and enclosed spaces.


RPK-16 with a drum magazine for 96 rounds

The new Russian RPK-16 light machine gun will be able to compete with the new ultralight Belgian machine guns. This model was originally developed as a Russian analogue of foreign machine guns chambered for the low-pulse 5,56 × 45 mm cartridge - FN Minimi and M249, which combine high firepower and excellent mobility.

In terms of its dimensions, the RPK-16 chambered for 5,45x39 mm is as close as possible to the presented FN Evolys. At the same time, the Russian machine gun is also lighter - it weighs about 4,5 kg. At the same time, Russian designers abandoned tape power supplies. RPK-16 is compatible with standard magazines for AK-74 and RPK-74. That is, box magazines for 30 or 45 rounds are available for it.

Also, a drum magazine for 16 rounds was created specifically for the RPK-96. The machine gun with this store has already been demonstrated at exhibitions many times. The declared rate of fire of the RPK-16 is approximately 700 rounds per minute.

            Yes, but there is still a question of maneuverability. If we talk about military operations in urban conditions, when you have to wade through tight rooms and rubble, the protruding sleeve can still get in the way. Plus a separate offensive moment: if a poor-quality link comes across, and the tape breaks somewhere in the backpack, the machine gunner will feel sad)) However, this is all sofa expertise; practice will show what is more convenient and when.

    They forgot about the cut-off RPD-44 with tape feeding. In Israel, the RPD was in service with the counter-partisan special unit "Egoz". The last time the RPD was featured in IDF photographs was in the 2000s.

        These are old photos from the now defunct country of Rhodesia - lower, with a bleed, without a stock. And upper Vietnam. I'm not a spy to post photos of secret units with a list of weapons - now Hamas will know laughing And you will be grateful drinks . I just wanted to say that popular recognition is the highest mark. With a slight movement of the saw, the light machine gun turns into an assault machine gun for action in the jungle or dense thickets of the savannah, and for urban battles.

          Not only, it also includes the ability to quickly unlock the store. And yes, this is about the fact that in this case you can completely control the weapon with one hand, including shooting. The machine gun from the article, by the way, most likely cannot, I can't imagine how easy it is to reload it with one hand, although everything is possible.

          On the run, pieces of tape are of course lost. In defense, in a trench, pieces can be picked up and equipped, if necessary. Unless, of course, you need it. And it seems that the tape is loose in tank PCs?

      With them, because the loose tape does not hang down and does not interfere with the maneuver. The ease of use of a weapon is its effectiveness in battle.
      With us, because the savings are the ability to use the tape many times.
      Different priorities.

      Well, in our RPD-44, the tape was not dragged, but fell off in pieces, either 50 cartridge or 30 cartridge ones, since in a long one it was fastened with cartridges in special connecting cells. Loose ones are loaded at the cartridge factory, our belts are made with special machines or manually from zinc, which is more versatile. The RPD machine-gun belt was well fastened in a ring, not very thick ones could use it as a belt.

      of course weighed about 10.8 kg but worked like a fairy tale. (7,62)

      I think it is overheating, but there are ways to deal with it.
      Presumably:
      -Application tactics.
      - Steel quality.
      - "Cold" grades of gunpowder.
      - Thickness and external configuration of the barrel.
      And also a combination of all of the above.

    The declared weight of the machine gun is approximately 5,5 kg... For comparison: the FN Minimi chambered for the same cartridge or its American counterpart M249 SAW weigh about 6,5-6,85 kg.
    fool In the city it is necessary not so much to "shoot" as to "react instantly", and with such a weight, it is far from being an assault rifle. Gentlemen Belgians, work on, and do not yell: "We laid the egg!" You are not Chinese, but civilized Europeans. A powerful machine gun turned out, but run with it through the ruins + weight of 200 rounds fool

      Technology rules.

      Where do you see new technologies in this machine gun? Aluminum alloy in the receiver (M16 = 60s of the 20th century)? Telescopic stock (M4 = 90s of the 20th century)? But there are two indisputable facts:
      1) rejection of the ammunition bi-system - only tape (hello to you FN MINIMI);
      2) rejection of a replaceable barrel (hello to all fans of the "quick change" sect, our FSE!).
      And what then is the innovation in the concept of this "spectacular" machine gun in comparison with the ancient one, like the shit of the mammoth RPK-44 from the middle of the last century? Probably a Kevlar bipod.

        Due to the lack of a quick barrel change, I think like you. However, for special units involved in low-intensity conflicts, this will not be a problem. But it could have been for the infantry as well. Over time, we'll see if FN is right. As for the news: 1) the expanded use of 3D printing in production 2) To load the tape into the machine gun, usually raise the lid, put a new tape on the feed tray, close the lid, pull the cocking handle in the chamber. first tour. Problem: This system is not compatible with the long top accessory rail. To solve this problem, FN Herstal has developed a completely new feed mechanism. The mechanism is now located on the side of the machine gun, the power cover folds back on the left side. The ammunition is guided and positioned almost automatically when the lid is closed, which significantly reduces the risk of jamming on the first shot, as was the case with previous loading systems. In addition, in the old system, one or two links usually remained in the tray, the gunner had to get rid of them before loading the next tape; this no longer applies to the new FN system as it automatically removes the last link.
        I hope the translator will translate everything well.

          This is no longer a problem for machine guns (USSR / Russia), because practical rate of fire is limited by tactics, combat conditions and portable ammunition. The quick-change barrel is not needed if the machine gun is capable of shooting all the ammunition from one barrel. Plus, when changing the barrel, there is a problem with bringing the second barrel to normal combat.

          Is there a problem, especially for a machine gun? In Russia, at PKM / Pecheneg, they put a dovetail on the left side of the receiver, thereby removing the sights from the moving parts of the machine gun.

          The mechanism is now located on the side of the machine gun, the power cover folds back on the left side.

          This mechanism will increase the width of the machine gun without a cartridge box, i.e. will create additional difficulties in carrying. But this is already a matter of ergonomics, i.e. user habits.
          In general, a rollback towards simplification of the design is obvious. The lightening system was not "bought" for free, but at the cost of introducing light alloys instead of steel and the absence of a spare barrel.

    This is a valuable feature. A single fire is very useful.
    And 750 rounds per minute is a practical rate of fire.
    We at Belgian MAG have always reduced the gas supply regulator

        Open bolt firing is a disadvantage for accuracy. But for a machine gun it is better for cooling.

              At the same time, the rifle turned out to be extremely complex structurally and extremely expensive to manufacture, which, together with the delay in setting up production, caused a very small - up to 10-12 thousand units - number of produced copies.

            You are welcome. But to be perfect, your machine gun, in addition to the short-stroke piston, must have a switch for firing with a closed bolt when firing single fire, and with an open bolt when firing in a burst. wink wink

                If I get you right. And like cars, a good car must have balanced power, traction and stability. The short stroke piston is just one piece. A long-stroke piston gun, but with a good shot and a good barrel, it will certainly be accurate. Hope I got it right.

                From what I've always read, in theory, a long-stroke piston increases mass and hence moment of inertia compared to a single bolt, making all phases of the firing cycle mechanically more reliable without increasing the overall weight of the weapon.
                The main disadvantage is the substantially lower level of inherent accuracy due to the increased moving mass that affects the shooter's control of the firearm, especially at the start and end of the piston / breech assembly stroke, and gas intake for assembly on the barrel. the barrel, which under the action of gases and pushes the piston back during the bullet barrel, creates a parasitic support of the lever, which strongly affects the barrel during the firing cycle.

                  I agree in principle. but I meant that we are not discussing a Marksman sniper rifle, but a light machine gun. and the Czechs seem to even make a sniper rifle out of Kalash. so we can assume that on a long stroke of the piston, you can get an acceptable accuracy of a single shot, an acceptable accuracy of the burst (for a burst, a small dispersion is useful, what would get the effect of a shot shot?) and sufficient reliability for a light machine gun. that is, on a long piston stroke is it easier to achieve the desired balance of properties specifically for a light machine gun?

                    generally speaking about machine guns, I think like you. However, in these new machine guns, which one user rightly called assault machine guns, more emphasis is placed on aimed shooting than high power. Therefore, companies use a short stroke piston, given that the same mechanics are used in the production of the rifle.

    I read an article in the old issue of the magazine "Weapon". So there ours, going on a business trip to the Caucasus, refused the RPK-74, preferring the PKM. Motivated by the fact that the characteristics of the AK-74 and RPK-74 are largely similar, but the latter is inconvenient in close combat. However, magazines from the RPK-74 for the AK-74 were widely used.

    For example: the Russian single machine gun "Pecheneg" in the bipod version weighs at least 8,2 kg with a length of 1155 mm.

    It would be the same with a manual one to compare, a weapon of a completely different class, how to compare a PP and a machine gun.
    It must be compared with the PKK.

    The machine gun is a competitor to assault rifles ...
    I, apparently, do not understand something ... A phrase from an anecdote pops up in my brain: "But there was a bear, that ... he wore a skin with fur outside." Here I am ... Like that bear. Something doesn't add up ...
    You can shoot 200 rounds of tape from your hands. Whisper. But what about barrel overheating? And with accuracy "at the end of the package" ... And most importantly - why! Well, okay, this is a publicity stunt. Promotion, so to speak.
    And weight? Do you always need to have a box with a tape for 200 rounds? And what about the balance as the rounds are spent? The store hangs on the right. And if the cartridges ran out, then what? At one time, smart uncles said: "If you did not have enough 8 rounds when firing a pistol, then 28 will not be enough".
    Or do we not expect to recharge the store? Do we still have a couple of boxes for 200 rounds hanging on the hump? Oooh!
    Not ... I understand ... "Tse Europa" ... This is the Russian barbarians' light machine gun accepts magazines from the machine gun. Barbarism, really ...
    And what about the BMP? Or in an APC? And where is the grenade launcher if sho and ... etc. etc.
    I can already hear: "Well, you stupid! It's a machine gun, not an assault rifle." Okay. So be it. I'm imbecile. But why is it? If this is not a 7,62 caliber, then this is not a machine gun. According to the possibilities.
    If this is closer to an assault rifle, then why 200 rounds and tape feed?
    There is only one explanation. Budgets are sawn not only here ...

        That is, a situation when visibility is limited, there are a lot of gizmos around that you can easily catch on and you need to quickly turn your head, "move the barrel" and shoot from the "zyu letter pose".
        Maybe I'm wrong, but the "device", which is 2 kg heavier than the AK74, with seriously large dimensions "across" and a dangling ribbon, is poorly suited for the situation "city, jungle, intersection". Even if the stock is folded to this "miracle of hostile technology", then it will not be much inferior in length to the AK with the stock unfolded ...
        No, well, they are pros ... Maybe it will save a soldier's life ... Not a fact that a soldier of his army, but it will ...

            You see, what a thing ... If we put RPK74 next to it and this is a "miracle of hostile technology", then in my, purely subjective opinion, RPK74 will provide me with the opportunity to complete the task and leave alive in a much larger ... "nomenclature", say so, combat situations than "this here".
            The "Belgian" has a lot that, in my opinion, makes its use inconvenient as a light machine gun. And as a single, he does not pull. No, I certainly understand that "in the absence of a stamp, they write on a simple one," but this is not a reason to bring a simple one to the customer when they ordered you a stamp.

              Well, as if this is definitely not a single machine gun and not an assault rifle. the only complaint about the rpk74 was the lack of a tape or a reliable roomy drum. Did FN guess right or not? they themselves do not know. have done and are now feeling the market. in the hope that the clients themselves will tell them whether they need it and in what quantities. or you need something else. then only practice will now tell.

    Every time we talk about a new weapon, someone says, "What's the use ?????????????????????????????????????????????????????? AK 47 is perfect. " “Even the Golf IV series was perfect, but technology is evolving. Everything can be improved. Otherwise, the Russian armed forces would not have. We are looking for a new rifle. Then the AK is a great weapon. But if someone is addicted to weapons, he would not resist if his life was only AK and M16. We have a disease, it is not our fault if it is never cured wink

    FN did a good job, the tape machine, unified with SCAR and ultra-light weight, a good, maneuverable thing, it is convenient and quick to transfer the vector of fire, "crush" the enemy with long bursts. Specialists in combat in urban conditions will appreciate this - the enemy will count the ammunition from the standard 30 charge magazines, and then he will not be allowed to raise his head for a very long time.
