Military Review

A company from China introduced a device for shooting from the shelter

26
Devices for firing from small weapons because of all sorts of shelters for a long time do not give rest to the inventors. Back in the years of the First World War, specially created periscope rifles, which allowed soldiers to fire without leaving a safe trench or trench, remaining inaccessible for return fire from the enemy, got their way into life. Later, both in Germany and in the USSR, weapons were developed with a curved barrel or with the use of a special kinky nozzle, which was intended for firing from around the corner, from various fortification devices or military equipment.


It is worth noting that the First World War largely initiated development in this direction. Turning to the positional stage, she forced the designers to think about creating a weapon that allows firing with “indirect” aiming. Similar developments have appeared in almost all armies that took part in this international conflict. A striking example of such a weapon was the French trench rifle, created on the basis of the Lebel Mle 1886 rifle. On this weapon, they decided to replace the usual straight butt with a special double-curved, also on the rifle two mirrors appeared on the brackets, which formed the simplest periscope. The shooter sent the cartridge into the chamber, locked the bolt, set the rifle on the forearm on the parapet, then through the mirror system looked at the scope and front sight of the rifle. Such devices did not receive special distribution.

During the Second World War, this kind of development was returned again. So, at the end of 1943, the German company Rheinmetall received an order to develop special tools - warped barrels, which were planned to be used on all standard Wehrmacht weapons, designed to use the 7,92XXNNXX mm machine-gun cartridge. These devices were designed to reduce dead zones from a distance of 57-150 meters to 200-15 meters. The first such sample of the special nozzle on the barrel (Krummerlauf, German - curved barrel) was intended for the Mauser K20k regular rifle. An experienced barrel, bent at 98 degrees, had an inner diameter of a smooth channel of 15 mm, and an outer diameter of 10 mm. At the same time, the results of shooting from him were considered unsatisfactory.

Change-Line-Free Shooting Tactical System


Realizing that the rifle ammunition does not fit, the German designers turned their attention to another cartridge - the 7,92x33 mm, the so-called "intermediate" cartridge; its bullet was shorter and the muzzle energy was smaller. The tests have shown that such ammunition is better suited for such structures, and only assault rifles that have just started to appear in the German army are better suited for a curved barrel. In fact, they became the only weapon model where such a barrel mattered and could be put into practice. In July, an 1944 assault rifle MP.43 with a nozzle on the barrel curvature 90 degrees showed the top leadership of the Wehrmacht. In the first embodiment, the rifled barrel had several venting openings. At the same time, during tests and shooting of such a machine gun, equipped with a curved barrel-nozzle, the shooting accuracy was considered quite satisfactory. When firing single ammunition at a distance of 100 meters, the dispersion was within 35 cm, and the survivability of such a lining on the barrel was about 2000 shots.

After the end of the Second World War and in 1950-s, such developments were again not in demand and lost their relevance. Again they were remembered only at the end of the 20th century, when various special forces units needed means to fire and monitor the enemy from behind the shelter. Such devices could be very useful during assault operations, for example, when freeing hostages from buildings, vehicles, etc. captured by terrorists.

In many ways, the issue of “firing around the corner” again became relevant precisely because of the growing terrorist threat. Conducting counter-terrorist operations, as well as the fight against well-armed and equipped criminals have become relevant for almost all states of the world. Local conflicts as well as fights in urban development among a large number of civilians, where there is often no possibility of using full artillery support, have become commonplace, and using grenades is not always convenient. In addition, the attention paid to the personal safety of soldiers has increased all over the world, which means that demand has reappeared for systems that would allow firing from around the corner, shelter, without exposing the shooting soldier to unnecessary risk.

“Corner Shot”


One of the prominent developments in this area was a system called "Corner Shot", which was created by Amos Golan, a former Israeli special forces officer, and the name of this system became a common noun. This device was a special rotary carriage, equipped with a video camera. It was easy to attach pistols of various caliber and other weapons, as well as a variety of non-lethal weapons, which are becoming increasingly popular, and various optoelectronic devices and devices. Despite its narrow scope, Corner Shot devices have become popular in many countries around the world. They are used by special forces in Azerbaijan, Israel, India, China, Mexico, Russia, the United States, and South Korea. Analogues of such a device for small arms were developed in India and Pakistan.

In this case, Chinese engineers would not have been Chinese engineers, if they had not attempted to develop a similar design. They decided to call their own project “Change-Line-Free Shooting Tactical System”. For the first time the Chinese development was shown at the 4-th exhibition of police weapons China Police Expo (CIPATE). It is reported that the device was created under the direct supervision of chief designer Qin Hanseng. It was presented in two versions: low-tech model CF-06, which is an optical-mechanical design and high-tech model HD-66, equipped with a video camera. In fairness, it is worth noting that both Chinese developments presented are not exact copies of Amos Golan’s Israeli invention, but have become their own. Of particular interest is likely to be a simpler model CF-06, which should cost several times cheaper than the more complex Israeli Corner Shot, which sells for approximately 4-5 thousand dollars.

The Chinese device "Change-Line-Free Shooting Tactical System", developed and manufactured by Sunlonging Photoelectric & Technology, is a platform carriage equipped with a pistol grip, shoulder rest, and an optical sight. It is equipped with a special rotary module, which is used to mount a pistol type QSZ-92, caliber 5,8x21 mm or 9x19 mm, while the manufacturer claims that other types of modern pistols can be used with the product. A periscopic lens was mounted on this module, and other accessories in the form of a tactical flashlight or a laser designator can also be installed. The Chinese module is able to rotate in both directions at an angle of 90 °. At the same time, the used optical sight has a variable magnification ranging from 1 to 4 times; sight field of view - 4-16 °; the exit pupil diameter is 5-9 mm, and its distance from the eyepiece is 70-76 mm. The total weight of the entire device is 3,85 kg. To facilitate transportation in the stowed position, the stock and sight can be easily removed.

Already now we can say that the development of the "Change-Line-Free Shooting Tactical System" from Sunlonging Photoelectric & Technology will be of interest not only to representatives of law enforcement agencies, but also, due to its simplicity and affordability, will be attractive to fans of airsoft.

    The development, of course, is interesting, but again, the pistol is taken as the basis and they dance around it. That's when they create a complex based on an assault rifle, or PP, then this will be a breakthrough.

    Curved barrel systems were equipped with our bunkers in fortified areas in the Far East. I personally saw a machine gun with a nozzle that allows you to shoot from cover without protruding. True, the accuracy and resource of such systems was not high, but it was suitable for massive fire.

      Only not with a nozzle but with a curved barrel, and that's all true of goryuns. The only one of the adopted kryvolokolov in the USSR were still experienced curvilinear PPSh, AK and RPD with a curvilinear nozzle

      If you are talking about Boyarkin, then his handicraft for ease of use was not even close to the corner shot or this Chinese did not stand because it has two key differences.The first Boyarkin simply placed a lens connected to the eyepiece with a light guide on the weapon (PM) (although a year ago he found out that there is also WI-Fi video cameras and announced a craft with a cheap Chinese camera from a door peephole) as a result, when shooting from its version, a hand with a weapon is exposed around the corner - in principle, the main thing here is not even the vulnerability of the hand, but the fact that for shooting it must be bent and it is not natural to aim by bending and turning the brush, in contrast to the Izrail or Chinese pribluds, where the weapon, or rather the device itself, is held as it should be, which provides a much faster, accurate and comfortable shooting. and the second shooter is tied to the weapon with a light guide, and in the "advanced" version a module with a screen dangles on his head in front of his eye, not to mention the picture quality, viewing angle and aperture in both cases.

    curved trunks, which was planned to be used on all standard Wehrmacht weapons, designed to use a 7,92x57 mm rifle and machine gun cartridge. These devices were designed to reduce dead zones from a distance of 150-200 meters to 15-20 meters. Horses mixed up in a heap - By that time, such Pribluds had been successfully used on standard Wehrmacht models for firing from behind shelters, the curvilinear nozzles were primarily developed for the Panzerwaffe to reduce the dead space of a tank not affected by regular weapons

    Well, the assault rifle is understandable, but General Maievsky in 1868 proposed making the gun barrel bent, the gunner was looking into the future.
    Of particular interest, most likely, will be the simpler CF-06 model, which should cost several times cheaperthan the more complex Israeli "Corner Shot", which is sold for about 4-5 thousand dollars.

    To paraphrase:
    "Chinese - born, Israeli - hanged himself")))
    This is a sad joke, you have to do something with these plagiarists.

    I think that they are all too smart - after all, the machine already has all this (butt, handle, scope), it remains only to add a hinge;)

    [quote] [/ In this case, Chinese engineers would not have been Chinese engineers if they had not attempted to develop a similar design.]

    At the same time, Chinese engineers would not have been Chinese engineers if they had not attempted to copy someone else's design. Now this is called an attempt to cut the budget, and this trendy trend has now come to China. Apparently, a large number of collective farm chairmen and Komsomol activists are expected to appear, they were usually shot from around the corner. If you look at the statistics and find out how many times such products have been used in practice to fight terrorists, it may turn out that there are no such cases at all.
    It’s enough to wind the web-camera with tape to the gun and connect it via USB to a phone or tablet, which is always at hand, it will turn out the same, only the cost is about 300 rubles. This is much less than 3-4 thousand dollars that you want to get for a crooked gun, therefore, such options are not considered.
