QSB-91. Chinese shooting knife scout

34
Knives that can fire multiple shots weapon quite specific. Very rarely, designers manage to maintain a balance between a convenient knife and a more or less efficient device for firing a shot. Despite all the controversies, and sometimes well-founded arguments about the absence of the need for such devices in service, shooting knives continue to be developed and manufactured, including in China. In this article we will try to get acquainted with the Chinese shooting knife of a scout, namely QSB-91.


General characteristics of the knife QSB-91

Chinese scout shooting knife designed in 1991 year. This is not difficult to guess from its designation. In the same year, it was adopted by the special forces of the People’s Liberation Army of China, where it is still used.

QSB-91. Chinese shooting knife scout


Looking at the QSB-91 knife, one cannot get rid of the thought that there is something in it that is familiar and familiar: just look at the blade of the weapon and the scabbard. But the handle of the shooting knife is very different from domestic developments, as it hides a mechanism that allows you to make four shots without reloading. Remarkably, this knife has four full rifled barrels, it provides a more complete disclosure of the potential of the used ammunition and relative accuracy when shooting. True, neither the ammunition themselves, nor the design of the pistol, provide noiselessness in firing.



First you need to get acquainted with the cartridge that is used in the weapon. The QSB-91 reconnaissance shooting knife uses Chinese-developed cartridges, namely the 7,62x17. This munition was developed in the 1964 year for use in a gun with an integrated PBS Type 64. In the future, this munition was used in other models of pistols, characterized by small dimensions. You can often find the opinion that this cartridge is similar to 7,65x17, known as .32 ACP, but if you put two ammunition side by side, the differences will be visible even with the naked eye. The sleeve of the Chinese cartridge is slightly shorter, and the groove is much wider and has a different profile. In addition, the liner does not have a protruding lip, while the .32 ACP, although small, is present. In terms of their combat characteristics, the cartridges are similar in principle, that is, very weak by modern standards.



The real diameter of the bullet cartridge 7,62x17 is 7,79 millimeter. Bullet shell, has a mass of 4,8 grams. From a weapon with a 70-80 barrel of millimeters, the bullet flies at a speed of 240 meters per second, that is, its kinetic energy at the muzzle is about 135-140 joules. If you assess the sober capabilities of this munition, then it is effective at a distance of no more than 10 meters, while the stopping effect is minimal, which makes it not the best choice for military weapons, even if it is as specific as a shooting knife. Perhaps the only hit that is guaranteed will lead the enemy down - in the head. But this is not the case with a pistol, not to mention such an “ergonomically correct” device for firing, like a knife. However, if you set a goal, then with proper preparation and long workouts you can achieve quite good results, especially since the cartridge for China is massive.

Design of the shooting knife QSB-91

The QSB-91 shooting knife is very similar in its design to some multi-stemmers. In the handle of the knife is placed four barrels located muzzle cut in the direction of the blade. On the handle there is a screw cap, in which the trigger mechanism is located and when unscrewing which the weapon is reloaded.



The trigger mechanism is a drummer that, when cocked, rotates 90 degrees, alternately standing opposite the capsule of each of the cartridges. Cocking occurs when you press the trigger, which is located on the site of the guard. The trigger is connected to the hammer with a long thrust passing through the center of the handle.

The arms are arranged in pairs, two on each side of the blade. To be able to aim, there are parts on the handle, which are primitive pillars and a front sight. They are located slightly away from the plane of the blade, because when fired, the knife will have to be kept tilted, respectively, and the trigger will also be tilted, which in general is not the biggest problem for a structure that is poorly adapted for convenient firing.

Positive and negative qualities of the QSB-91 gun

Among the main advantages of the Chinese shooting knife scout QSB-91 can be noted the ability to make four shots in a row without reloading. Trunks 86 millimeters long - also an obvious plus. It is impossible to ignore the fact that the knife itself has not lost its multifunctionality, although for many it now seems insufficient by modern standards.



Negative moments of the weapon is much more. First of all, it should be noted not very well chosen cartridge for a scout's shooting knife. No matter what anyone says, but one shot, which is guaranteed to neutralize the enemy, is much better than four, which can not always show an acceptable result in hit effectiveness. But even the cartridge is not the main drawback, but the gun barrels that remain open even when the knife is placed in the sheath. Taking into account the fact that the knife is still a working tool, we cannot exclude the possibility that the trunks may be clogged with earth or debris, which in the case of a shot, at least, the shooter will be surprised.



It is not entirely clear why it was impossible to change the design of the scabbard, especially if the knife is in them, then it will still not be possible to fire a shot. Rather, a shot can be made, but the bullet will hit the edge of the sheath. In the end, it was possible to simply invent a stub for the barrels worn on the blade, or to install rubber membranes in the muzzle sections, similar to those in the old PBS.

Conclusion

Like any shooting knife, a Chinese shooting knife of a scout is a specific weapon, which has both a number of advantages over other similar structures, and a number of drawbacks. One cannot estimate such a weapon one-sidedly, since its effectiveness will depend on the specific situation and skills of the shooter. However, the QSB-91 knife was adopted by one of the largest armies in the world almost a quarter of a century ago. This means that this weapon copes with its tasks, otherwise it would be replaced with something else, more perfect.

    Some kind of ambivalent impression of the knife: 1) for a scout, such a knife is a very good thing. If it is equipped with a device for cutting barbed wire, it’s all pretty. 2) if this is a reconnaissance knife, then it must be noiseless, otherwise what kind of intelligence? Imagine this picture: you are in reconnaissance and you need to make a passage in the barbed wire, and there are patrols and sentries. Well, let's say one or two with a knife, and which on the tower you shoot with a shot from a knife, but others will hear the shot and all your intelligence has covered itself with a copper basin.
    In my opinion, it is more convenient for the Chinese to use an ordinary knife and PBS type64, and this QSB is not a candle to God or a poker line

    Well, I don’t know ... for me, the 18-20 centimeters blade with a tip for cutting blows is best, and the handle has something like a shooting handle under a Kalash cartridge, as the last argument in the fight. And the design is the simplest .. and the handle is poorer ...

    The idea is interesting, but not brought up as they say “to mind,” but if you make the caliber smaller, the sleeve longer, the charge larger, the bullet -5,45 - something will work.

    Well, ours is at least silent. Under SP-4. Yes and range at least 15 times higher. About XNUMX meters you can hit the target, even if you shoot offhand, without aiming, you just pointed and fired. It’s easy to get into the zinc from under the cartridges such a distance. So to say the last chance, if you shot the whole b / c to the AC and PB. Although in this situation it is no longer noiseless laughing Well, or the effect of surprise for an enemy who is going to take you prisoner, a shot can be fired without taking a knife from its scabbard, though you can’t talk about accuracy in this case. There are different situations, for example, let’s penetrate an object, you are mining, in your hands NRS, with which you squeeze the detonators, and then the enemy appears, you don’t have time to get the gun, shoot from the knife, and then you take out the gun. Initially, it was done to neutralize sentries or sentinels, in the case when it is impossible to approach him at a distance from the knife , as well as for combat swimmers. In those days, the saturation with silent weapons of reconnaissance units left much to be desired. Even in the early 2000s, reconnaissance platoon from silent weapons had one PB at the commander’s platoon and several AKM with PBS, but almost everyone had LDCs. Now Of course, the situation is already different, there are VSS and Shafts, PB, APB, and reconnaissance AKMs are still in use, in general, almost half of the personnel with silent weapons. I'm talking about military intelligence, and not about MTR. So now these are knives are no longer relevant, and have not heard of their successful use in combat operations before viyah.No still more than a knife exactly budet.Ya not mean our LDC-2, but this is not the Chinese miracle.

    In this product, one of the trunks could be replaced by a LCC. A similar opinion on equipping such products with a "red dot" has been repeatedly voiced. Or IR laser visible in the NVD, if you strongly press on stealth.

    In weapons, as in life, the main thing is the correct concept yes !
    And in order to construct a mechanism or device well, you need to clearly understand why we need it, what we want to achieve and what tasks to solve with our product. And if there is no clear idea, then all sorts of amazing “punches” are obtained, suitable for window dressing and exercises, but practically unsuitable in battle (no, well, try to shoot yourself with this knife-type: “The Chinese are not surrendering!”, Of course you can , although it is unlikely to succeed ..).
    In this case, the concept of a Chinese knife is controversial. However, like the knife of the LDC (-2), but in the Soviet LDC, at least they didn’t really abuse the blade, but the Chinese overdid it, were too sophisticated, copied, aunt in a yew, the “holey” Soviet (bayonet-knife) Kusachki NaPilnik, which did not use good fame in the Soviet troops (as opposed to the “eSVeTeshny” bayonet for AK-47). In addition, any openings and "universal cutouts" - openers of beer bottles weaken the blade, leveling the main function of the knife, for which it is intended to chop and cut! Look, for two (3,4,5, ...) functions we chased, they didn’t realize it at all, it’s not some kind of “multitool”, but a combat knife, on which the life and death of a warrior depends, and that in war, the most important thing is the flawless performance of a combat mission!
    The scout's combat knife blade must be an effective kill tool, and everything else from the evil one! The handle configuration should correspond to this killer function as much as possible, and you can try to enter and "device" into this "configuration, but with minimal damage to the main function! Do not forget about the scabbard, here you can" unload "auxiliary functions without them excesses and fanaticism, because the “Warrior” already has a universal “multitool”, so there’s no need to duplicate it — the soldier doesn’t carry his own (and his unit) with him and himself, but in the field and mountains each gram takes its own weight forces (so necessary for the battle) and even an insignificant "straw" breaks the back of our native "camel"! yes
    If the Chinese had stuck pistol cartridges into a knife (for what?), Then there was a need for more caliber to choose, so that the stopping action of the bullet would guarantee, upon impact, instantly depriving the enemy of the ability to attack and defend, otherwise this is just an “exotic” for collectors of “cool toys” "and has no military value, like a firearm! The handle of their shooting “knife” is simply monstrously “sadomasochistic” yes Well, you can’t abuse the famous stoicism of the Chinese soldiers request .
    Honestly, our Chinese comrades do not surprise me, they were, in the long run of the USSR, “copyists”, without a creative twinkle. However, as the "new generation" of our fellow designers of the light "shooter" and such an LDC "cold guy" has already ceased to surprise, they are too lazy to think that they really don’t like their work as the Creator-Designer, they didn’t choose by calling ?!
    But the designers of machine-gun grenade launchers and heavy machine guns, my lasting Respect!
    Forgive me, dear Mark, all of the above applies only to the Chinese "product" described by you, and not to your, very important and very useful, informational Work on the search and description, which are certainly interesting, for acquaintance and for borrowing rational grain (if it found), foreign and domestic weapons.
    Indeed, in the process of reading and living, albeit epistolary, discussion, a common alloy of thoughts is formed, from which new designs of designs and, ultimately, new patterns can be born. Perhaps the future designers will draw something for themselves, as I scooped, I collected a bit from childhood, I myself, although I was lucky (I realized this late), my dad was a Designer from God and the basics of the profession unobtrusively grafted me a grinder smile
    The article is relevant for improving the armament of the domestic army, thank you, Mark!

      So that's the question. Why shove regular cartridges into a knife, and even to the detriment of ergonomics? Don't they have pistols? Our LDCs under SP-4 are a completely different matter, there is at least some sense here. For example, the knife does not clang the shutter and does not scatter sleeves, like the same PSS. It will pull a saboteur on weapons in large-scale conflicts, when special weapons are not enough.
      As for the Chinese crafts, only the option with a lack of weapons comes to mind. Just four cartridges are theoretically enough to shoot someone, finish off with a knife and take possession of normal weapons in this way. It’s clear that the scouts are no side here. It is possible to use it as a service weapon in wartime, again with a shortage of weapons. For example, rear services to protect against raiders and marauders. Here the fact of arming with a firearm is important to ensure an advantage over an enemy armed with improvised means, such as axes, shovels and kitchen knives. At the same time, the weapon is noisy, weak, and under a rare cartridge, so if it gets into the hands of bandits, it will not allow them to roam. Given that there are far more people in China than military arsenals, I would bet on such an application.

        The knife is a melee weapon and in a one-on-one battle four barrels clearly give an advantage and it does not matter at its disadvantages. Above, I wrote a concrete example when such a weapon has a vital need. I think the Chinese came from this.

    Something similar, but certainly better, and with a different scheme, I did as a teenager under a small cartridge. Unfortunately, while he was in the army, one relative found him and poher.
    More than 40 years have passed since then, and I now understand that the knife should be a knife, and a gun a pistol.
