The throwing range of a hand grenade is determined by the physical condition and skills of the fighter, but does not exceed several tens of meters. To attack more distant targets, it is necessary to use technical means - a variety of grenade launchers. At the end of the seventies, as an experiment, a disposable grenade launcher "Penal" was created, which was distinguished by its small size and rather high combat characteristics.

Problem and Solution


The hand grenade is small in size and weight, but its flight range does not exceed 30-40 m. Grenade launchers can shoot hundreds of meters, but have significant dimensions and weight. In a number of situations, a fighter may need a light and compact system suitable for throwing a grenade over long distances. Under-barrel grenade launchers became a good solution to this problem at one time, but they could only be used with machine guns, which could lead to difficulties of an ergonomic and operational nature.

At the end of the seventies, the designer of the Tula TsKIB SOO Valery Nikolaevich Telesh began to develop an original grenade launcher, combining convenience and high combat qualities. The product with the working name "Pencil" was based on a number of curious ideas and was distinguished by the most simple design. The grenade launcher was planned to be made disposable and always ready for use. He had to use a VOG-25 shot or other 40-mm ammunition, incl. non-lethal equipment.

The resulting sample could be of interest for various structures. First of all, the customer could be an army interested in the development of a system of infantry weapons. The non-lethal "Pencil" could be of interest to various structures from the Ministry of Internal Affairs or the KGB.

Simplification course


The Penal disposable grenade launcher externally was a metal cylinder with closed ends. On the side there was a simple trigger mechanism with a safety pin and a ring. The length of the item was 200 mm, the diameter was approx. 45 mm, weight with ammunition - 700 g.

The main part of the grenade launcher was a rifled barrel. It was made in the form of a thin-walled aluminum tube with the necessary holes and internal elements. In the front of the tube, rifling was provided, similar to the thread of the GP-25 grenade launcher. To fix the shot in the working position, there were stops inside the barrel.

The trigger was placed on the side of the barrel. It consisted of a spring plate with a drummer, its support and a safety catch in the form of a check. When fired, the spring was supposed to provide a blow to the grenade primer.

Any adaptations to improve ergonomics weapons were not provided. It was proposed to take and hold the grenade launcher by the barrel-body. Horizontal guidance was carried out "by eye". Experienced grenade launchers did not have the means for vertical guidance, but, according to some reports, in the future it was planned to apply a simple rangefinder scale to the hull.

The "Pencil" product was to be assembled and equipped at the factory. A VOG-25 shot or other product with suitable characteristics was placed in the central part of the barrel. In the back of the barrel, behind the grenade, an anti-mass was placed in the form of a set of round plates made of aluminum or plastic. The ends were closed with knock-out covers that were torn off when fired. The recoilless system has reduced the requirements for barrel strength and made it lighter.

As part of the Penal system, it was proposed to use different ammunition. First of all, this is the VOG-25 fragmentation grenade and its modifications. It was also allowed to use the unified product "Nail" with an irritant like CS, smoke grenade VDG-40, etc.

The design muzzle velocity of the grenade reached 90 m / s. The maximum firing range is 300 m. Low accuracy was expected, but it had to be compensated for by the action of the ammunition: the scattering of fragments of a combat grenade or the formation of a gas cloud from a non-lethal product.

By simplifying the design as much as possible, it was possible to reduce the cost of mass production. The serial "Penal" was not much more expensive than the VOG-25 fragmentation grenade. Consequently, for the price of two grenades, it was possible to get not only ammunition, but also a device for throwing it at a long distance.

Recoilless hand weapon


From the point of view of the principles of operation, the "Penal" was a recoilless weapon with recoil damping due to the release of counter-mass. This feature imposed some restrictions on the application.

The grenade launcher could be carried in any suitable pouch or otherwise. Before the shot, it was necessary to remove it and remove the ring with the check. After that, the product was ready to fire. The "pencil case" was required to be taken away from oneself in order not to fall under the influence of powder gases or flying out elements. It was also necessary to monitor the safety of others.

With the help of an eye gauge and a scale, the shooters had to aim at the target, after which it was possible to press the trigger. This led to the ignition of the grenade charge and to a shot. The grenade tore off the front cover and sent to the target, and the powder gases through the rear cut knocked out the counter-mass and the cover. This action of the weapon made it possible to do without tangible recoil.

No prospects


It is known that at least one experimental grenade launcher was manufactured at TsKIB SOO, which was used in tests. This product was tested at a test site and its real characteristics were established. Apparently, the prototype was repeatedly reloaded, which showed the fundamental possibility of manufacturing not only disposable grenade launchers.

The design parameters and fighting qualities were confirmed. However, this fact did not affect the real prospects of the grenade launcher. According to known data, none of the departments, considered as potential customers, did not want to purchase "Pencil cases". In the existing weapons systems of the Ministry of Defense, the Ministry of Internal Affairs and the KGB, there was simply no place for such products. The military and security officials continued to use standard hand grenades and grenade launchers of all existing models.

According to some sources, "Penal" was nevertheless adopted by one of the power structures and was even produced in small batches. However, such information is not confirmed by anything - and contradicts reliably known information from other sources.

The reasons for the failure of the Penal project are obvious. First of all, the prospects of this development were negatively affected by its proactive nature. None of the departments ordered the development of such weapons - because they did not need them. According to the test results, interest in this product did not appear.

The Penal project offered an original solution to the problem of the grenade throwing range, but the need for such a solution is questionable. It is difficult to imagine a situation in which a fighter will need the most lightweight grenade launcher capable of sending a single grenade to 200-300 m without special requirements for hitting accuracy. In real situations, it is possible to get by with hand grenades and various grenade launchers with different characteristics.

Thus, the main result of the Pencil project should be considered a test of the viability of the original idea. It was found that the technical tasks set can be solved, but their result is of low practical value. As a result, the experimental grenade launcher did not reach the series and did not enter service. But he left an interesting mark in stories domestic grenade launchers.

    This is how long and persistently the domestic weaponry thought was moving through the pencil cases and "grenade shovels" to new heights of design excellence. And at the same time, but in a completely different place somewhere in the jungle, one could occasionally hear strange "gurgling" sounds preceding distant explosions.

      The only thing these two devices have in common is that they are a "portable grenade launcher". Everything. More than one position, they do not intersect.
      But from what Telesh was inspired in reality, it was from German over-caliber grenades, 39 years old and later, for a signal pistol. Moreover, he was inspired, not cheated. For structurally, in general, everything is different, and there are enough fundamental differences - both a stepped chamber with high / low pressure (I did not dig much, but it seems that he was the first to come up with it), and an entirely flying ammunition (I will assume that again the first in the world really working).

        That product itself is good. But you need to carry blank cartridges with you, load them on time, and so on. It will work only on exercises.


        In order not to dull in the heat of the battle, you need either grenades launched by a live cartridge, or a separate barrel for grenades.


        Europeans initially opted for a through-hole barrel grenade. We chose a grenade launcher with a flying away sleeve. The Americans are a classic unitary cartridge and breech-loading grenade launcher. Subsequently, the Americans imposed their decision on the Europeans.

              The article states that the "Pencil case" is disposable and is equipped at the factory.

        What is the algorithm for using? Unbending your mustache and shooting blank? So what? Farther than a hand throw? What about accuracy? Doesn't it detonate at the moment of shooting? How long does it take to put on pribluda? Questions, questions. As cadets, during field trips, we still didn’t give a shit when the officers left for their wives in the evening. But this is all a collective farm and handicraft. There is a great chance to kill your own.

    I once read about the project of a disposable grenade launcher, not for automatic carbines, but for relatively light and small submachine guns. The grenade launcher is attached to the submachine gun just before the shot, and after it is automatically thrown forward. This allows you not to increase the weight of the sub-machine gun. The caliber of the grenade launcher is 60 mm. Offensive grenade. The firing range is 100 meters. Can be used as a hand grenade.

            There is no way to attach a grenade to the old-mode Kalash 47 / M / 74 / 74M, since the front sight is too close to the muzzle, but on new ones where it was moved further away, it is theoretically possible, but you need to be able to close the gas outlet tube before firing so that the pressure in the barrel pushes only a grenade (NATO rifles had a special tap for this). But there is no particular sense in all this. Various cumulative grenades are weak in modern armor, AT grenade launchers are common and much more effective. And OF-grenades lose to grenade launchers and AGS-am, and there are quite enough hand-held grenades.

              The Telgren grenade from FN does not require the 1.5kg GP-25 to be carried on the machine. It is launched by shooting a live cartridge. Recoil energy 50-70 J. Accuracy 2mx2m square at a distance of 100m. Reduced damage radius - 10m. In vain an abandoned topic.

              Okay, but this applies to old pomegranates. For example, "Energa" and "Super-energy" were launched with a special cartridge without a projectile and with a starting charge of 2,55 grams. But the newer Mecar or Fn fires conventional ammunition. Generally speaking, the shotgun grenade launcher also has its advantages over the hand grenade, grenade launcher, and even over the grenade launcher. Although use should be limited to anti-personal use

      Yes, here somehow it would be more convenient to fly. You can at least get into something and even damage.

      And the size of that fly is like that of 4-5 such thermos flasks. Longer, perhaps.

        For harassing and distracting fire, multiple explosions are better than one. On the other side of the VOG and from the barrel holder, you can throw it.

    Non-lethal "Penal" could be of interest to various structures from the Ministry of Internal Affairs or the KGB

    Rather, the FSIN, not the Ministry of Internal Affairs / KGB. But they have such "toys" and so on more than. A grenade launcher is really enough for motorized riflemen.

    According to known data, none of the departments, considered as potential customers, did not want to purchase "Pencil cases"
    "Castrat", without support on the fore-end of any type and design, butt and fire control handle and, most importantly, the simplest sighting devices, it is correct that it is not one of the departments, and even with an eye on the eye, "miscarriage" and only ... there although there are gloomy "geniuses", but not to the same degree ... bully

    And we had a STANDARD grenade launcher on a regular M-16.
    A special nozzle was put on the barrel in front of the flame arrester.
    The people called the "rose". She was holding a grenade
    with a plastic body, similar to a mortar mine.
    It was necessary to shoot with a blank cartridge. Powder gases push
    grenade.
    The main thing was not to confuse and not shoot her in the ass with a real bullet! belay
    Then "little fluffy animal". laughing

    The system is mura, in my opinion. The strongest return, no precision.
    You carry these grenades on yourself - God does not allow them to slip and fall on them! sad

    It seems to me that the problem of the "Pencil" is not that such a weapon is not needed, but that it is necessary to shoot from it the devil, which means that it will go somewhere, with homing by the will of Allah. It is much easier to give a soldier a grenade launcher, which is only twice as heavy (by 800g), while it has normal sights and ergonomics. Or, if he does not use a machine gun, issue a RShG based on an RPG-26. Yes, the weight is more - 4 kg, but the effect is much better.

    How to shoot from it so as not to hit yourself, crap flying out from behind?
