A new submachine gun is hard to come up with. Swede vs. Singaporean
Submachine gun yesterday, today, tomorrow. Submachine guns from different countries and continents are often very similar, like twin brothers. But they say about everyone that he is the best. Today we look at the CBJ-MS submachine guns of 6.5x25 CBJ-MS by the Swedish company CBJ Tech AB and CPW Kinetics, which is offered by Singapore’s ST Kinetics, and in several calibers at once: 9 × 19 mm Parabellum, 5,7 × 28 mm and 4,6 × 30 mm. In the previous article, “Pistols and machine guns of the era of change and ammunition for them,” we examined it a bit. But not very detailed and without comparison with analogues. Today we fill this gap ...
As you know, Sweden has created in the past and is still creating many interesting types of weapons, always with high, “Swedish” quality. So the creation of a new submachine gun for the army of Great Britain was taken first by the concern SAAB-Bofors. But when the British decided to abandon him, CBJ Tech AB took on the new submachine gun, designated CBJ-MS PDW (Personal Defense Weapon - personal defense weapon). As a result, the original PP appeared chambered for 6.5x25 CBJ-MS, which is also used in Glock pistols and HK MP5 submachine guns.
Today it is difficult to come up with something “such”, “incompatible with anything”, something they would not have invented, so many structural improvements are reduced not to the design itself, or even to production technology, but to design. Here and in the submachine gun CBJ-MS there is nothing revolutionary. A free shutter is used, and shooting occurs from the open shutter. USM allows you to shoot and bursts, and single fire. To select the shooting mode, you do not need to press any “buttons”. Everything is reduced to pressing the trigger: strongly pressed - you get shots in a queue; if the pressure is weak - a single shot. Convenient to say. No need to move "levers". It became fashionable, and long ago, so that the cocking handle remained fixed during firing. But here it was transferred to the back side of the receiver and gave a characteristic conical shape. Since the front grip for holding is in such a way that the hand of the shooter can accidentally touch the hot barrel, a fuse plate is placed under it. The receiver is made of stainless steel by stamping, which increases the strength of the weapon.
The store, like the Uzi, is located in the Ingram in the pistol grip, which traditionally reduces the size of the weapon. But what is interesting is that the spare shop was thought of by the designers to insert it into the front handle to hold it, and this can already be considered one of the highlights of this design. Its location allows you to save time on recharging. Yes, very little. But better such savings than no! As for the stores for CBJ-MS, they are used with double-row filling cartridges for 30 and 20 cartridges. However, there is also a drum magazine on 100 cartridges with a long neck, also included in the handle. Well, the simplest shoulder rest is easier, nowhere is it easier, from steel wire, but there is Picatinny on the receiver (where is it now without it?) To mount a collimator sight on this PP, or whoever it wishes. Moreover, for this submachine gun provided for ... bipod and quick-release barrel! So you can shoot out of it for a long time, a lot and with taste - relying on a bipod, and the overheated stem can be quickly replaced with a new one!
In fact, the Swedes turned out the same "Uzi", but its own, "Swedish", and with the ability to conduct a long machine-gun fire and more ergonomic, according to the requirements of the time. Even the color of him and that - green, which today represents another trend: to create a weapon in camouflage coloring.
However, the most interesting thing about this submachine gun is not its design, but the small-caliber cartridge used in it, which has a very high initial velocity of the bullet, which is made of ... a tungsten alloy, and fixed in a plastic tray. Moreover, the diameter of the bullet is not just small compared to other bullets for submachine guns, but very small - just some 4-mm, and this is despite the fact that the diameter of the barrel in him and so all 6,5-mm. That is, the bullet to this submachine gun is also sub-caliber, and it is not surprising that its initial speed is higher than that of the Mosin rifle - 830 m / s, although the barrel itself has a length of only 200 mm. At the base of the liner for the new cartridge is the 9x19 liner, but with a long barrel, pereobzhatym to 6,5-mm. Naturally, the return of such a cartridge when shooting is very small, and the accuracy of automatic fire, as well as the accuracy of single shots, increases most significantly.
On top of that, with this cartridge, this submachine gun has an impressive effective range, which is 300-400 meters for it, which is twice as high as the 9x19 cartridge. In addition, due to the high lateral load and small diameter of the bullet, it has a high flatness and penetration. At a distance of 230 meters, this bullet, for example, can easily pierce a CRISAT-type body armor, and at 50-meter distance an armor plate is 7-mm thick.
However, no wonder they say that there are spots on the sun. Everything is good, but due to the small caliber and high speed, the stopping effect of the bullets of this submachine gun approaches zero. Is that a bullet just hit the head! True, you can remake both the shop and the software itself, chambered for the caliber 9x19, and then “everything will return to normal”: the stopping effect will be high, but bullet-proof vests will be too tough for him!
Now let's take a look at the Singapore ST Kinetics submachine gun, first shown in 2008, for comparison. It was originally created under the 9 × 19 mm Parabellum cartridge, but the design allows the use of 5,7 × 28 mm cartridges and even 4,6 × 30 mm cartridges in it. It is enough to change the barrel, the bolt (and that is not all, but just a bot!) And the store.
Initially, it was supposed to be a self-defense weapon for those servicemen who, according to the state, do not rely on an assault rifle. That is, this PP was created not for special units and the police, but for the army.
A semi-free type shutter has a lever-like braking like the Kiralee's gate, which seems to be supposed to reduce recoil when firing. All "digging" and levers "controls, respectively, the requirements of the time - bilateral, for both right-handed and left-handed. The Singaporean's cocking handle is also double-sided, except that the Swedish one is more original in design. There is a front handle, but Singapore engineers haven’t guessed to shove a spare shop into it. But they invented to make the back of the pistol grip transparent, which makes it possible to see the flow of ammunition, because the magazine to the submachine gun is also made transparent. The original decision, do not say anything! Butt more difficult than in the Swedish PP - it is retractable, telescopic. One Picatinny rail serves as an installation for a collimator sight, since there is no mechanical sight. The second bar is at the bottom, so the front grip is installed on it, although a laser pointer and a tactical flashlight can be installed, that is, the Singaporean has more opportunities here than the Swedish one.
Among the shortcomings of “Kinetics”, experts note a too high rate of fire (900-1100 vsr / min.), That is, a high consumption of cartridges, often completely unnecessary. But on the other hand he has a relatively small weight, size and, together with a folded butt, he is easily transferred like a pistol in a special holster.
Thus, we see that today, in different parts of the world, which are very far apart from each other, very similar structures are being created. As, however, before. Attempts are being made to use new cartridges, but ... so far, they have never created a universal cartridge for quality. Attempts are being made to improve the accuracy of shooting, but, apparently, in the framework of traditional design everything has already been achieved. And if you use an unconventional approach? We will tell about it in the following material ...

It seems to be portable weapon this CBJ-MS, but if you take it in hand, then ... it will not be small at all!
With traditional Swedish quality!
As you know, Sweden has created in the past and is still creating many interesting types of weapons, always with high, “Swedish” quality. So the creation of a new submachine gun for the army of Great Britain was taken first by the concern SAAB-Bofors. But when the British decided to abandon him, CBJ Tech AB took on the new submachine gun, designated CBJ-MS PDW (Personal Defense Weapon - personal defense weapon). As a result, the original PP appeared chambered for 6.5x25 CBJ-MS, which is also used in Glock pistols and HK MP5 submachine guns.
So this “Swede” looks like from the right side. The window for ejection of spent cartridges is traditionally large.
It is difficult to think of a new one, so why not improve the famous?
Today it is difficult to come up with something “such”, “incompatible with anything”, something they would not have invented, so many structural improvements are reduced not to the design itself, or even to production technology, but to design.

Since the front grip for holding is in such a way that the hand of the shooter can accidentally touch the hot barrel, a fuse plate is placed under it. The receiver is made of stainless steel by stamping, which increases the strength of the weapon.
And this is how it looks equipped with two shops and a silencer.
Universal handles and 100-cartridge shop
The store, like the Uzi, is located in the Ingram in the pistol grip, which traditionally reduces the size of the weapon. But what is interesting is that the spare shop was thought of by the designers to insert it into the front handle to hold it, and this can already be considered one of the highlights of this design. Its location allows you to save time on recharging. Yes, very little. But better such savings than no!

CBJ-MS in section.
Patron around the head!

CBJ-MS with a set of devices: on the left - a silencer and a barrel, at the bottom - a bipod and a charger for filling the store, then a cartridge assembly for using a submachine gun inside combat vehicles, and 0 shops on 20, 30, and 100 cartridges.
On top of that, with this cartridge, this submachine gun has an impressive effective range, which is 300-400 meters for it, which is twice as high as the 9x19 cartridge.

CBJ-MS (top) and ST Kinetics (bottom)
Now let's take a look at the Singapore ST Kinetics submachine gun, first shown in 2008, for comparison.

It is enough to change the barrel, the bolt (and that is not all, but just a bot!) And the store.
This is how it looks. Immediately striking transparent back of the handle.
Initially, it was supposed to be a self-defense weapon for those servicemen who, according to the state, do not rely on an assault rifle. That is, this PP was created not for special units and the police, but for the army.
A semi-free type shutter has a lever-like braking like the Kiralee's gate, which seems to be supposed to reduce recoil when firing.

And in his hand, he, too, is by no means small.
