9 mm submachine gun SR.2M

The 9-mm submachine gun СР.2М developed in TsNIITOCHMASH (it was shown at the MILIPOL 2013 exhibition in Paris) is intended for hitting manpower, including in personal protective equipment of the second level (body armor of type CRISAT), as well as unarmored technical means at distances to 200 meters.

SR.2M is distinguished by the presence of attachment devices for fixing aids - with Picatinny rails, which allow mounting on weapon collimator sight, laser designator, tactical flashlight. It is possible to install a tactical silencer to reduce the level of the unmasking factors of the shot.

In the basic configuration, the SR.2M is equipped with a KP-CP2 collimator sight with two marks - when shooting up to 100 m and up to 200 m.

Folding metal butt allows you to reduce the overall dimensions of the submachine gun when carrying and provides directional shooting with both the folded butt and the folded butt.

Combat shooting is carried out by cartridges:
9-mm pistol cartridge with SP10 armor-piercing bullet
9-mm pistol cartridge with an ordinary bullet SP11
9х21 mm cartridge with armor-piercing tracer bullet 7BT3

Performance characteristics
machine gun weight without magazine - 1,55 kg
muffler weight - 0,34 kg
Picatinny rail weight - kg 0,18
weight of shoulder rest - 0,30 kg

length:
with folded / folded butt - 367 / 605 mm
with a silencer with folded / folded butt - 554 / 793 mm
with silencer and shoulder rest - 800 mm

rate of fire - 950 shots per minute

sighting range - 200 meters

I am surprised that the picatinny rail is attached to the receiver cover, because backlash is inevitable.

[avt]

"Heather" or what? Well, yes, it can only be photographed at an exhibition in Paris.

[Bongo]

It seems to be used by special forces of the FSB in the North Caucasus.
But they released a little, like pistols for this cartridge.

[Bongo]

You are not right.
The barrel length of a standard "Uzi" is 260 mm.
Barrel length SR-2M "Veresk" -174 mm.
The main difference between them is in the scheme of automatic operation. The Uzi uses a free shutter.
In CP-2M because of the powerful ammunition, based on the vapor engine and the butterfly valve.

Dear, why bother studying the materiel and comparing the design .. I saw a magazine in a pistol grip, which means an ultrasound. the main thing is to quickly throw out a comment that the first thing came to mind

[Bongo]

I wonder how effective the "silencer" is when using the 9X21 cartridge, or is there a special subsonic ammunition of this dimension?

[bazilio]

Quote: Bongo

Is there a special subsonic munition of this dimension?

It seems not, in the line of SP 10-12 cartridges the "slowest" 7N28 SP11 has an initial bullet speed of 390 ms, the rest have a high speed. It seems to me that it is quite possible to create a subsonic cartridge based on the joint venture. Otherwise, the muffler acts as a flame arrester.

[makarov]

Dear !!!
And what does the range on the line ??? Let's start from the powder mound. For example, in PM, it is 0,23-0,25 g., In 9X21, the filling is 0,5 g. Based on the table technique, then 1d. gives 1 liter of gases, and now you can compare the amount of exhausted gases yourself and the required area of ​​PBS for their cooling.
Due to the specifics of the cartridge itself, it is not widespread, and is used in a narrow range of shooters. In addition, the sleeve dulce is equal in diameter to Makarov’s, which limits its use in foreign samples.

Dear !!!
And what does the range on the line ???

I mentioned the line of cartridges that are produced and for which there is info. It's good about the volume of gases and the area of ​​the PBS, but you probably forgot about another factor of the "loudness" of the shot - the bullet breaking through the sound barrier, which gives a noise comparable in strength with the sound of the burst of gunpowder in the cartridge. No PBS can affect the speed of the bullet.

[makarov]

SW Bazilio.
The question that you raised is not subject to discussion, so I will send you an answer in PM.

[Jack7691]

Read carefully - "tactical" silencer! What does this mean ? And the fact that sound damping is not achieved completely, but only until an uncritical level of sound pressure is reached when firing with standard ammunition - in your own words, "so that your ears do not hurt when firing in enclosed spaces!"

[makarov]

Your conclusion is not a priority, but as an addition to the main version.

[Jack7691]

And this is not a conclusion, but the truth - you need to carefully read the text. And I don’t see the main version - I only see abstruse rants with attempts to call on the experts.
By the way, if you are so smart, can you tell me how the silencer is implemented on the MP5 - is there a 9Para cartridge with supersonic barrel exit speed? And why cannot this be implemented with us? For information - sound suppression when using a standard cartridge (9x18) is implemented in the PB - its speed when firing from the PM is 350 m / s. Just do not be smart that you hear the sound of the shutter, and therefore the result is not quite ...

[Bongo]

You are mistaken, in the "silent version" of the MP-5SD, just a subsonic cartridge is used.

[Jack7691]

You are mistaken - the usual 9Para is used there

[Bongo]

Nothing like this, open any directory.

[Jack7691]

Discover ...

[Bongo]

Well, of course ... maybe there are no subsonic subsonic 9X19 cartridges?

[vanaheym]

The MP-5SD does not use subsonic ammunition, as it is designed for conventional cartridges that accelerate to subsonic speed thanks to the ported barrel.

There are 2 versions of MP5SD: early (in the photo below) and modern (in the photo above).

In his catalog, Chris Bishop once wrote:
“The MP-5-SD is equipped with a silent firing device.
It is a casing worn on a barrel with 30 holes. ”
The description, apparently, refers to the first prototype PBS.
I did not find images of this model.

And here is what PBS looks like for the modern version of MP5SD

Experts say this design is outdated by today's standards, but still very effective.

The silenced MP5SD it fires standard ammunition types with the same effect.
The use of special subsonic ammunition is not necessary.

wise men, it is necessary to take into account the temperature of the gas medium and its pressure .....

critically, this is 120 decibels (howitzer shots) followed by death. and shooting indoors with pistol cartridges does not even lead to damage to the hearing aid, with a long-term only slight decrease in its sensitivity ........

[Jack7691]

This text only confirms my letter above - "abstruse rantings with attempts to become experts"

With your permission, I will add one digit from the description of the BSS for MP5
(from the official site)
QD silencer (p / n 985660)
Fits: Submachine Guns MP5 / MP5K
Sound suppression: 32 dB A

PBS for G36, HK416 A5, depending on the model, have similar properties:
26.8 to 33.7 dB A

[StolzSS]

Maybe it exists, but I have not heard about this. And as for efficiency, well, shooting without headphones allows))) in principle, in a city bustle, even probably they won’t understand from the habit that PP works ... although of course it will depend on the conditions ... I think it will be very noisy at night in any case ... although who Well it will be used at night ....

Flame arrester, in short.

[Rakti-kali]

A rather interesting sample, although not without flaws, such as the shutter lever on the right side of the receiver, and the stupid distribution of the location of the fire mode switch and fuse switch, which should be swapped.

[wolfhunter2035]

It seems like a modification came out (I don’t remember the name), these shortcomings were taken into account there, as well as the iron itself was better processed (the fighters using CP2M complained about poor-quality processing, they always got cuts using Veresk), and even with these flaws Veresk is very good ))))

[a.hamster55]

What is he "half-cut" - ugly. Dad Carlo was too lazy?

[the47th]

Let me give you a quote from an old film: "So they are sitting in a tank, and not performing on the stage of the Bolshoi Theater."

[Silent]

The close-up photographs say that the workmanship is not perfect, which cannot but worry. Appearance Appearance is more dangerous than possible internal problems associated with workmanship.

[Owl]

I checked such a product to the fighters two years ago, I didn't really like the rough manufacture of the butt, I had to make significant efforts when unfolding, the "iron" worked without comment, I spent 8 rounds for alignment and verification, after that I performed automatic exercises at ranges of 50-100 meters, not interesting, all targets were easily hit (performed the exercise using only mechanical sighting devices), a worthy weapon.

[Wiruz]

Great unit. Paired with SR1MP, it’s generally THING!

So probably with a hangover was ... Really ugly! Actually, like all our weapons ... Do we really have no designers?

[Kir]

And it depends on what is meant by the designer, since in one of his main meanings he is a Designer, so something, but we didn’t seem to have any special problems with creative engineering, but if you put any gloss on, well, yes, there is , although they need to "work" with what tool they look like, but the fact that the quality of processing is not so hot, and all the pribluds for some reason with foreign designations, this is extremely regrettable.

[a.hamster55]

Well, here's a handsome man from merchandisers!

[b-612]

probably from designers, after all)

[Blot]

No, this is in my opinion a perversion, for a gangster cattle ...

[Blot]

By design, I mean something completely different.

[the47th]

Something like this?

Would you like to draw checkers or go? Of course it is not glamorous, but reliable. Although in peacetime the metal should be processed more carefully, thank God there are no Germans near Moscow and there is no need to drive the over-plan and deadlines.

[a boat]

Oh, we would be so where the rogue!

[Blot]

From this series only "Kashtan" is a very cute product!

[alexx83]

C'mon, okay. the machine. Give two)))

[a.hamster55]

IMHO like a chestnut, but a little too big for me, like Stechkin. Well, at least they would handle it better for exhibitions, otherwise it is really a wartime assembly. Therefore, we lose the conclusion of contracts.

[Jager]

The processing is rough, the inscriptions are all on the injection (it casts thoughts on the presence of counterfeit Chinese parts - irony), the damper is massive and seemingly heavy ... And so the machine looks interesting!

[ko88]

I did not hold this PP in my hands, but the design shows that the sample is very ergonomic.

[aver]

How many different PPs have already been released in recent years, but our policemen seem to be in a war - with the Kalash!
