In Brazil, adopted a new machine IMBEL IA-2

38
The Brazilian Defense Ministry at the end of October 2013 decided to adopt a new machine gun under the designation IA-2, which was created by IMBEL (Industria de Materiel Belico do Brasil), according to the Brazilian portal Forcas Terrestres. The decision to adopt a new assault rifle for the Brazilian army was taken during a special meeting of the General Staff of the Armed Forces of Brazil, which took place on October 18 of the year 2013.


The development of this machine has been conducted in Brazil since the beginning of the 2000-s. It was created as a replacement for the FN FAL lightweight automatic rifle, as well as the HK33 and M16A2 assault rifles. Brazilian designers created a machine for the parallel use of two different patrons: NATO 7,62x51 and NATO 5,56x45. The 7,62 caliber is also used in the sniper rifle version. The effective firing range, depending on the caliber used, is 600-900 meters, and the maximum firing range is up to 3600 meters. Weapon has a pistol grip, plastic forearm and butt. Picatinny rail strips can be installed on the machine, which are used to install various attachments, including laser designators, sights, tactical lights, etc.

Depending on the modification, the mass of IA-2 ranges from 3,2 to 3,7 kg., Without cartridges. The length of the machine is 993 mm for the version in the caliber 5,56-mm and 740 mm for the version of the caliber 7,62-mm. The fire rate of the IMBEL IA-2 is 650-750 per minute, depending on the model. The initial speed of the bullet - 850-900 m / s. The machine can be equipped with magazines for 20 and 30 cartridges.

In Brazil, adopted a new machine IMBEL IA-2

Based on IMBEL IA-2, a whole family of small arms types was created, including a 7,62-mm sniper rifle, as well as millimeter 5,56 and 7,62 mm rifles and a special shortened version of the CQC assault rifle for using the 5,56-mm cartridge. Despite the fact that the order to accept the new machine into the armament of the Brazilian army was signed only in October 2013, the weapon has been actively supplied to the troops and the Brazilian security forces since the end of last year. All were released more than 1500 copies of the weapon.

The new Brazilian assault rifle was created on the basis of the Belgian model FN FAL. The main difference between these two models of small arms is that the Brazilian machine gun uses a butterfly valve as opposed to the inclined gate, which is used on the original Belgian rifle FN FAL. At the same time in the IMBEL IA-2 you can still see the Belgian roots.

Belgian roots

The FN FAL light automatic rifle (from the French Fusil Automatique Leger) is a NATO rifle produced by the Belgian company Fabrique Nationale de Herstal. The FN FAL is one of the most common and internationally recognized automatic rifles. Initially, FN FAL was created under the intermediate cartridge caliber 7,92 × 33 mm, which was widely used by the Germans during World War II, later prototypes of the rifle under the .280 British cartridge appeared. Still later, FN FAL was converted to use the standard NATO cartridge 7,62 × 51 mm, which was adopted as a single for all countries of the North Atlantic alliance. During the Cold War, these weapons acquired the very interesting nickname "the right hand of the free world."


Initially, the FN FAL rifle was designed as a small arms for active combat in the middle distance. As a result of the replacement of the intermediate cartridge 7,92 × 33 mm with standard NATO ammunition, an increase in the muzzle energy of the bullet occurred, a direct result of which was an increase in the range of the rifle. As a result, the Belgian gunsmiths came up with a model that is able to be used effectively enough at a distance of up to 1000 meters when firing single shots and provide the shooter with satisfactory accuracy of fire when firing in short bursts at a distance of up to 200 meters. This sample of small arms was created to arm the infantry units, so the FN FAL is easy to maintain.

The FN FAL rifle was actively used in many armed conflicts of the second half of the 20th century. The automatic rifle was the main weapon of the Israeli army during the Six Day War and the Doomsday War. It was also widely used during the Falkland War (both sides of the conflict used the rifle). Australians and Canadians used a rifle in the Vietnam War, it was also used in numerous armed conflicts in Africa, as well as local clashes with illegal armed groups in the countries of Southeast Asia and South America.

Some later modifications of the FN FAL are still in service with various security agencies (where allowed by local laws), as well as police units. It is widely used throughout the world. In various versions, this automatic rifle was in service with the 55 armies of the world, including the Brazilian army.

FN FAL

Like any other weapon, FN FAL has its advantages and disadvantages, which directly follow from the design of the weapon. To some extent, they will inherit and the new Brazilian machine IMBEL IA-2.

Advantages
Quite high accuracy of shooting at a distance of up to 1000 meters when firing single shots.
High striking, penetrating and destructive ability of the used NATO cartridge 7,62 × 51 mm.
Simplicity of incomplete disassembly of the model, the possibility of maintenance without the use of special tools.
A heavy and relatively stable bullet along with a powerful cartridge allows you to effectively fight in dense vegetation and rough terrain, without fear of bullet deflection as a result of collision with small vegetation branches or foliage, and also ensures effective defeat for soldiers protected by body armor.

Disadvantages
Very low accuracy of fire when firing bursts, even in the version of the manual machine gun, characterized by the presence of bipods and weighted barrel.
Fairly low resistance to clogging weapons with sand, small debris and dusting.
The large weight of the ammunition and, as a result, the restriction imposed on the ammunition carried by the soldier.
Removal of powder gases near the front sight, which can create additional difficulties for the shooter when aiming while conducting intense fire.

In general, it can be noted that the FN FAL light automatic rifle over the years of its operation has shown itself to be a fairly reliable and unpretentious sample of small arms. In fact, it is not an assault rifle, but an automatic rifle. Despite the fact that in this tactical niche today, a sufficient number of new types of small arms have appeared, FN FAL does not lose ground, remaining a proven time and a fairly effective weapon.

    I DO NOT BELIEVE. Even when firing by a subunit in a position "in the area", neither where nor when did I meet the methods of firing range from standard small arms at a distance of 3600 meters.

    From the very beginning, you should pay attention to the used rifle cartridge of 7,62 × 51 mm, which implies that for comfortable shooting a larger weight of weapons is required compared to machine guns of other calibers. Life has shown that 7,62 × 51 mm for the machine is redundant.

    The new Brazilian assault rifle was created on the basis of the Belgian model FN FAL

    He shot and disassembled from all versions of Imbel (MD-2 and MD-97), the FN FAL did not stand there, except for the configuration of the receiver, trigger, and handle. By design, it is more FN FNC. Even in appearance, AI-2 is an ennobled MD-97. But I won’t argue much, in January I still go to LA, and I’ll figure it out!

      2. Honestly, I have not seen her any instructions or any documentation where indicated. But the Brazilian border guards have specimens with shooting for 30 thousand shots.
      3. Carrying on the sand is not recommended, only because the stores are from M16. In a rifle, fairly large tolerances of average dust are not scary. The most common delay is the failure to deliver a cartridge from the magazine.

        Gentlemen, the holivar "FN FAL-copy of SVT-40" has ceased to be mainstream even before the crisis of 2008. The commonality of goals with equal training of designers and practically equal (but not identical) material base led to SIMILAR solutions.

        From that and structural similarity of models.

    4,5 is not quite easy (except for the landing version). The ancestress weighs less than 4 kg. And in automatic mode it’s rather difficult to control the shooting.

      To begin with, the disassembly is no different from the disassembly of the FAL.
      The latch on the left side of the handle snaps off, breaks the receiver, removes the receiver cover. You take out the shutter frame, disconnect the shutter larva. With the help of a cartridge, a stopper is pressed on the gas regulator; it is removed with a gas piston and a return spring. All incomplete disassembly. It turns out 6 main parts. AK has 5 of them! In accuracy, it is almost like AK because of the heavy bolt frame.

      Unfortunately, I can answer this question when I am in Paraguay. Honestly, I did not ask such a problem. But in my subjective opinion, if we compare the MD-97 with the AK-74, then the Brazilian has a thicker barrel, and the automation is shorter. But again, the return spring is more powerful, like the cartridge. Accordingly, we get parity, the difference in percentages ... As I shoot on the machine, I’ll figure it out.

      The external ballistic parameters of the weapon and the cartridge within the same external ballistic solution are practically not the same, they have an inevitable natural dispersion. This is expressed in the dispersion of bullets (trajectories) when firing.
      In the general case, the dispersion of bullets during firing is the result of a combination of many factors that can be divided into the following:
      weapons and conditions for their use;
      cartridge, its ballistic and structural characteristics;
      meteorological conditions of fire;
      shooter, his condition, level of shooting training and shooting skills.
      These factors are interconnected and interdependent, dispersion from some factors manifests itself depending on others. For example, meteorological conditions of firing affect dispersion depending on the ballistic qualities of the weapon, mainly from
      flatness trajectory; for a shooter, the dispersion results during shooting depend on the characteristics of the weapon, etc.

        The following factors affect the dispersion of bullets when firing from the cartridge side:
        ballistic characteristics;
        bullet stability when flying in air;
        design features of bullets;
        physicochemical properties and stability of gunpowder;
        the degree of accuracy of the manufacture of cartridges.
        A favorable effect on the accuracy of fire is provided by the persistence of the trajectory, which depends on the initial velocity of the bullet and the ballistic coefficient. With flat trajectories, the influence of meteorological conditions on the flight of bullets and on their dispersion during firing is less. For the same purpose, heavier bullets having greater lateral loads and a lower ballistic coefficient are preferred if they satisfy other requirements.

          A partial violation of the stability of bullets during flight has a noticeable effect on dispersion.
          The necessary stability of the bullets is achieved by choosing the appropriate stroke length (steepness) of the rifling in the new weapon, certain dynamic characteristics of the new bullets for the existing weapon, as well as by the density of the press-fit of the internal elements of the bullets in the production process, eliminating their dynamic imbalance.
          Adverse conditions for accuracy of fire are usually created with a complication of the internal construction of the bullet. The more internal structural elements of bullets, the more conditions are created for increasing dispersion. Especially with a tracer. Tracer bullets are usually 1,5-2 times greater dispersion in comparison with ordinary bullets. To some extent, the lateral stiffness of the bullet affects the dispersion. In this regard, bullets with a lead core or with a thicker lead shirt are better suited for good accuracy of firing. They also wear less cuts. To ensure good accuracy of shooting with fired bullets, except
          effective plumage, required necessary rotation during flight to compensate
          lateral components of aerodynamic force.

            The uniformity and stability of the physico-chemical characteristics of the powder have a known effect on the dispersion of bullets, since they affect the spread of the maximum gas pressure and the initial velocity of the bullet.
            A great influence on the dispersion of bullets during firing is exerted by the accuracy of the manufacture of cartridges, their elements, installation and the general culture of cartridge production. It matters: the accuracy of the charge (dosage) of the powder charge, the impact composition and the igniting ability of the igniter capsule, the accuracy of the weight and shape of the bullet, the diameter of the bullet along the leading part, the securing of the bullet in the barrel of the cartridge case and the magnitude of the bullet-extracting force, the position of the center of gravity and the moments of inertia bullets. This is the main dispersion factor when sold (existing) cartridges. The accuracy of the manufacture of cartridges is contrary to the requirements of efficiency and the conditions for their mass production. Acceptable cartridge accuracy is established by manufacturing practice. Established accuracy standards
            change in the direction of tightening tolerances only in special cases, for example, in the manufacture of batches of model and target (sports) cartridges.

              A number of characteristics are used to quantify the dispersion of bullets (hits), including dispersion radii, core dispersion bands, mean (probable) deviations, and others. All of them are associated with the midpoint (center) of dispersion or impact (STP).
              Based on long-term shooting experience, it was found that the dispersion of bullets (shells,
              trajectories) obeys the normal law of distribution (errors). The basis of this law
              lies the scattering scale. It is obtained by dividing all the dispersion in any direction with a sufficiently large (in the infinite limit) number of shots into equal bands containing a certain percentage of holes. Different columns of the scale reflect different detailing or approximation.
              The scale division bar containing 25% of the holes is called the median (probable) deviation, which can be in height (Bb), lateral direction (Wb) and range (Vd).
              In the process of firing at accuracy (dispersion), a natural dispersion of the dispersion characteristics is obtained.

        I will answer as asked, in science:
        With a large number of shots (more than 20), a certain pattern is observed in the arrangement of meeting points on the dispersion area. The dispersion of bullets obeys the normal law of random errors, which in relation to the dispersion of bullets is called the law of dispersion. This law is characterized by the following three provisions:
        1. The meeting points (holes) on the dispersion area are uneven - denser to the center of dispersion and less often to the edges of the dispersion area.
        2. On the dispersion area, you can determine the point that is the center of dispersion (the midpoint of the hit), with respect to which the distribution of the meeting points (holes) is symmetrical: the number of meeting points on both sides of the scattering axes, which are equal in absolute value to the limits (bands), is the same , and each deviation from the scattering axis in one direction corresponds to the same magnitude deviation in the opposite direction.
        3. Meeting points (holes) in each particular case do not occupy an unlimited, but a limited area. Thus, the dispersion law in general terms can be formulated as follows: with a sufficiently large number of shots fired under almost identical conditions, the dispersion of bullets is uneven, symmetrical and not infinite.

        When firing from a machine gun, the recoil and tossing factor is suppressed. So almost all vibrations remain)))

          Good afternoon, dear timeout!
          It is very pleasant when people who read textbooks give an answer to your comments. Although initially I asked a question to your opponent, I will ask a clarifying question.
          Shooting is carried out indoors with a temperature of plus 20 gr. C, pressure 760 mm Hg, lack of wind. A basing machine is used to conduct accuracy tests of firing from ballistic weapons with cartridges of an exemplary batch. As you can see, we eliminated the meteorology, the arrow, minimized the impact of weapons and cartridges of gross parties. But there is dispersion. So how can we conclude unambiguously that dispersion is associated with the barrel (or cartridge)?
          Best regards, Dmitry!

    More reliable M16 is already more than a solid model. No matter how they scolded the M16 (I myself sin by this), but this is still a pretty reliable weapon. Let us recall at least the competition held in SAS, where the C8, which in essence is a little modified M4, overtook the vaunted G36 and SIG551. At the same time, SIG, which various pseudo-experts on reliability equate to our AK, was behind everyone. Although the network often does not meet the most flattering reviews of the Brazilians themselves about MD97, the closest relative of IA2, but still this unit seems more preferable than any new-fangled plastic things.

      Of course, it is clear that they have factories for licensed production of FALs imprisoned, that it will be much cheaper to make weapons on their basis ... and the troops are accustomed to it, all operational features are already known ...
      But it was possible to take the same M16 for the base .... ??????

    Reliability test result in dusty conditions, Aberdeen Proving Ground (USA). 60000 shots were fired for each weapon model; delays were distributed as follows.
    XM8 (based on G36) - 127;
    Mk16 - 226;
    NK416 - 233;
    M4 - 882.

    In the same place, on repeated testing after increase in lubrication, the number of delays at M4 significantly decreased, although still it did not reach other models. The fact that the XM8 has become a leader is also not very surprising, because it turned out to be more reliable than its older brother G36. In the SAS competition, the tests were carried out more diversified, they say the tested samples were almost torn to pieces, squeezing out everything that is possible from them. Total, in the overall standings and won the C8, apparently not the last role in this was played by the poor quality of the G36 trunks and the abundance of plastic. As you know, G36 barrels after intense shooting give simply fantastic results - for 100 m spread from a half meter or more, for 500 m a spread of several meters. In addition, plastic, despite its sufficient strength, has a number of unpleasant properties - heavy-duty plastics cracks after prolonged use, less hard ones absorb shock better (for example, the mechanisms work when fired), but are more susceptible to temperatures, even prolonged exposure to sunlight can Negative influence. And plastics that combine the best qualities of both options do not yet exist.
