Experimental small arms developed by the USSR

Often it comes to the latest and unparalleled in the world Russian weapons... Unfortunately, for some samples, the term "has no analogues in the world" has already turned into a kind of meme. However, there are truly unique samples of domestic weapon systems and complexes, many of which have already been put into service, and many have remained either in the drawings or in the format of prototypes.

Many unique options for weapons belong to the development of the Soviet design school.

One of the unique types of small arms is the AO-36 assault rifle. The machine has its main feature - it is double-barreled. In this case, the sample presented at the stand of TsNIITOCHmash is considered. The review is presented on the Lazarev Tactical channel.

One shot of such an assault rifle - two bullets left at once in the direction of the target. As conceived by the designers, this was supposed to increase the destructive power of the weapon and would help to use the machine gun as an effective means, for example, to suppress enemy manpower.

The expert in the video notes that during the tests AO-36 showed a high accuracy of fire. In comparison with the Kalashnikov assault rifle, the AO-36 showed an accuracy of 3,2 times higher.

The video also provides an overview of the unique Soviet underwater machine gun, which hit a target in a layer of water at a distance of up to several tens of meters.

In comparison with the Kalashnikov assault rifle, the AO-36 showed an accuracy of 3,2 times higher.
In fact, it is somewhat different.
During the tests, it was found that the accuracy of fire from the AO-36 in terms of the "area of ​​the core of dispersion" from the "standing with the hand" position in comparison with the 7,62-mm AKM is 3,2 times higher.
The parameter "scattering core area" and the parameter "accuracy" are slightly different things.
Accuracy is the cumulative distance between each subsequent hit on the target. The lower it is, the correspondingly higher the accuracy of fire. And the "core of dispersion" is a rectangle that contains 50% of the hits. This metric is used to assess the likelihood of hitting a target by comparing the size of the target and the size of the "core dispersion".

Thank you Informative commentary

used to assess the probability of hitting a target

Only a very lazy person calculates the probability of HIT at the core of the scattering (the intersection of two core bands). Because it is very approximate.
Not lazy computes over the entire scatter grid. And it is more convenient - in a spreadsheet using the formulas, as expected.
In addition, it is not said by the number of which the accuracy was determined: by the same number of holes on the target or by the same number of shots, and for AO, a shot is a volley of two bullets.

If he missed, or missed, he has a butt. While the enemy is looking at the bullets, run up to him and give him a painful butt on the sopatka, it’s unfit to watch, everything is secret!

What was unique yesterday is becoming typical today. But in the development of small arms, Russia in the past had unique things today. Presumably, this school will show itself in the future.

Recall at least three-barreled salvo firing assault rifles designed by G.A. Korobov, which were developed in 1962-65 as part of research and development to improve the effectiveness of firing individual automatic infantry weapons. To ensure a controlled and low dispersion rate, the three bullets in the queue had to leave the weapon in a very short period of time before the recoil felt by the shooter would begin to move the weapon out of the line of sight. For this, Korobov used three horizontally located barrels, combined into one block and, when fired, giving a three-bullet salvo in 0.1 seconds (which corresponds to a theoretical rate of fire of 1800 rounds per minute). To ensure a comfortable perception of the recoil actually tripled in comparison with the AKM assault rifle, the recoil of the barrel block was used in the assault rifle, while, to simplify the supply of cartridges, the magazine with the receiver was also rolled back in the weapon body, which had a bullpup layout. The barrel bores were locked with a single vertical wedge gate. To power the cartridges, specially designed three-section magazines were used, which had three parallel compartments for 15 or 20 rounds each, one per barrel. The three-barreled machine gun showed good results in increasing the probability of hitting a target from unstable positions. However, despite the markedly increased hand firing efficiency compared to the AKM, the three-barreled machine gun had many inherent design flaws, such as a movable magazine, strong recoil, the inability to fire single shots or bursts of arbitrary length. In general, such weapons had no prospects for adoption. But what it looks like! - Just a fantastic blaster! - Such that you can shoot in science fiction without "makeup".

Naturally, in the presence of such a movable mass as a built-in magazine for 45-60 rounds, in total with recoil, it led to a significant "bumpiness" of all weapons ...

impossibility of firing single shots

Such a multiple launch rocket weapon in the "machine gun" form factor is hardly necessary, but for light machine gun, for which a single fire is not so important, such a scheme was quite suitable when eliminating, for example, a drawback in the form of a movable store block.

impossibility of shooting .......... bursts of arbitrary length

That is, I pulled the trigger, and all the contents of the store in white light as a pretty penny ?

You wrote something wrong ...

And if the barrel is overlaid with unpolished diamonds, then a bayonet is not needed. He ran up and cut off his head with a barrel. You can also add glass to the windows to earn extra money.

The photo seems to hint - whatever they try to do, it turns out to be similar to AK ...

[zenion]

Everything that is new is unexpected, as in ancient times it shoots through the barrel. No, that would be through the sight, or throw stones, everything is like the AK, also through the barrel, with the help of gunpowder, not matches.

[zenion]

One bullet went straight to the heart, and the second flew in from the rear, she skillfully maneuvered. There is no such thing anywhere else and will not be. Who needs such a weapon to clean two barrels. There is no such thing in analogs and catalogs.
