AK-103, AK-203: On the differences in modern domestic small arms

64

Russian gunsmiths are working to improve the small arms weapons... This is due to the modern needs in combat, with the need to increase the effectiveness of firing from various distances.


To date, many small arms have been developed, which are based on proven models, but at the same time have received a wide range of innovations and additions, including modified ergonomic indicators.

At the same time, it is extremely difficult for a layman to understand new types of weapons. For example, in the differences between the machines of the so-called "hundredth" and "two hundredth" series.

Thus, the AK-103 assault rifle, as a rule, in its standard configuration has two strips for attaching additional elements. One of the planks is located on the right, the other at the bottom. With their help, you can retrofit the machine gun with a tactical flashlight, an additional (pistol) grip, etc.

Also, the machines of the "hundredth" series have a folding polyamide stock.

Kalashnikov assault rifles of the "two hundred" series have been on display since 2018. One of the differences from the AK-103 is the flame arrester instead of the compensator muzzle brake. At the same time, this element of the machine reduces the toss of the barrel quite effectively. In the AK-203, pins are the fasteners for the barrel armature elements.

Details about the differences in modern domestic small arms are described on the Kalashnikov channel:

    Only it seemed to me that the flame arrester is still not effective enough to reduce the toss, and the barrel toss of the 203 is much greater than that of the 103 with the compensator?
    And the picatinny rail on the removable non-rigid shutter casing is also a so-so solution, albeit a beautiful one.

      Why did the very first, AK-103, not pull the shutter after inserting the magazine?
      And he started shooting.
      Was there a cartridge in the barrel, right?
      And if he deftly pulled the shutter at the same time as the magazine insert, why didn't he do it on the next ones?

        Why did the very first, AK-103, not pull the shutter after inserting the magazine?

        The presenter twitched the cartridge, only he did it very quickly, almost imperceptibly. Here's a screenshot of that moment:

          And that he twists the shutter through one place, left-handed? Or is this a fashion? If the bolt on the weapon is on the right, then for the right hand, on the left for the left. It is much more convenient to insert the magazine with your right hand into the machine, fixing the machine at two points, the butt on the shoulder and the left hand behind the forearm, leaving the direction of sight and weapon on the enemy, not looking at the magazine and the bolt, and not on the weight and lowering like this bespectacled man, who looks and looks for the shutter with his eyes. Now is the right hand pressed to the body?

              With his left hand only for the shooting range, and for the prone position or from the knee, this clown did not show the change of store. Thank God that the bolt handle is not being altered to the other side for the sake of these ... not ours.

                Agree. All these show-offs with high-speed reloading while standing, and with throwing the store into the bushes - these are more exercises for paintball, filming videos and show-off in front of ruddy girls. In battle, the magazine will be required to reload from zinc, and standing up is not always possible to shoot. And in general, something tells me that such "brutal well-dressed professionals" will be the first to be dumped from the battlefield, thinking that they are too good to risk their lives here, and the brunt of the battle will be pulled out by ordinary guys who reload in the old fashioned way ...

      I also drew attention to this, generally without further ado, expansion joints are very popular in the private sector, where shooters are trying to reduce the recoil as much as possible. For a soldier, this is not a question of minimum shooting per year ...

    5,45 caliber is more accurate, the bullet speed is higher and the recoil momentum is small.

      Yeah, "more precisely" just for some reason, most automatic rifles in 5.56 have greater accuracy than AK in 5.45 caliber. All these "remakes" are like a 50 year old woman dressed in new outfits. All these planks of picattini, pischmatini do not change ANYTHING in the weapon. The barrel is thin and does not have sufficient rigidity, the receiver drives when firing (see the video with a slow-motion camera and compare with the M4). Inside, a heavy "bolt carrier" flies here and there, which does not help the accuracy and accuracy either.
      Nothing new 200th series, except for the wound picattini rails, practically did not give. The same thin barrel, the same thin receiver, and the same heavy bolt action. It's like a 50 year old woman trying to hide her age under layers of makeup. Yeah, the recoil momentum is small, as well as the penetration ability of the bullet. Shoot with 5.6 (aka 22LR) - there the recoil momentum is even less.

        Do you need reliability or a little accuracy?
        The gaps between the parts are the main difference between the AK and the rest of the weapon. Better still reliability than the dubious quality of "accuracy", which depends more on the quality of the cartridges and on the skill of the shooter. If bench accuracy is checked, then only from the cartridges and the quality of the barrel.

            In vain you are so on conscripts. There are not good people among all categories of military personnel (there are more normal ones), and officers and warrant officers and contract soldiers with conscripts. And with conscripts, we plowed the Caucasian heights in Chechnya, Dagestan, Ingushetia, and dragged mortars with mines on our humps, and they went into hand-to-hand combat without fear of anyone, and they stormed Grozny, officers did not hide behind us. Therefore, you should not be so about the soldiers!

              There can be no two opinions about the "conscript monkeys". But with regard to Afghanistan, I will object for one very simple reason - it was not the army with fancy guns that lost, but the politicians. The US Army could certainly completely clean up Afghanistan, there is no doubt about that. Only the politicians did not set such a task; in my opinion, the policy pursued by the United States was not aimed at defeating the Taliban. Moreover, the Taliban ultimately did not win a military victory.

              On this topic, the war in Vietnam is immediately remembered. According to the northerners themselves, if the United States had carried out a ground operation by cutting the path of Ho Chi Minh, the North would have lost. And the US military offered this to politicians, but the politicians refused, and in the end it was one of their decisions that led to defeat.

          Well, if you take the same barrel, you could make it ribbed or frame, and insert it into a larger and longer receiver, this will not worsen the reliability (on the contrary, it will improve cooling and strength), but the barrel vibration will be significantly reduced, but why is it KK, you can't raise money on this. And yes, the point here is of course not in the QC itself with its managers, this is typical for all large manufacturers.

            Actually, they've already done it. in the USA they sold a variant of the saiga. It was called here SAIGA M. The barrel is 20.5 inches long and 0.75 inches thick. The thickness of the stamped receiver is 1.5mm. There were no machine-gun "stiffeners" on either side of the barrel housing (unlike Boar). Saiga M was sold here in 3 calibers. 5.56, 5,45 and 7.62x39. A very good rifle. True, it was necessary to finish it:
            a) There was no place to put a flame arrester. The front sight had to be removed, drilled out, put back and cut for the second transverse pin. Then it was necessary to cut the barrel from the outside so that the flame arrester could be screwed on.
            b) The receiver itself, from the inside, it was necessary to drill, make grooves in the drilled one and screw a feeding ramp to it and take it on a lokite so that it could use 30 charging Kalashev magazines (by the way, Saiga M in 5.56 works great with Galil stores. from the Vepr 5.56 to which give the Bulgarian (and they are 48-50 bucks a PIECE).
            c) The entire MSA had to be pulled out to be made in the USA, the pistol grip should be screwed on, and the butt for the AK made in the USA.

            All this took 3-4 hours of work and cost $ 100 in spare parts. (with the cost of the Saiga M itself at $ 400). You could have put a folding stock, then it would have cost more. The exit turned out to be a beast machine. In terms of accuracy, it is not inferior to the average AP15, much more reliable, but a little heavier (all the same, the steel receiver will be heavier than the one made of aircraft aluminum.

          This is not a question of just one bottle of cognac ... Although everything can be solved much easier, the more conscripts in the army, the more the question of reliability begins to prevail, but the more professionals become in the army and the size of the army can be reduced, the more the question of the effectiveness of weapons becomes, and accuracy in it is not the last place

            That's right. A professional will also clean the weapon in time and will not use it instead of a scrap.

                  Why was? She is. Only you gave an inverted example. The rifle did not break, but seized when not treated properly. Like any weapon. Your example was formed from a series of defamatory articles about the USSR and Stalin. Therefore, I think it is wrong.

                    And not just the Marines. The Wehrmacht and Finns loved SVT, it was a welcome trophy that the Germans and Finns immediately used. By the way, the G43 is practically lapped with the SVT40. There is also a matter of the QUALITY of recruits. For example, American conscripts had no problems either with Garand (when he was brought to mind), or with BAR. This is how I understand Garand was not much easier than SVT40, I think that Soviet draftees in 1941 would have had problems even with Garand. Just when in 1914 you had 27% literacy and almost no heavy industry (thanks to tsarism), in the USA in 1910 the literacy rate was 92%. It is IMPOSSIBLE to overcome such a lag in 25 years, although under the leadership of Stalin, the greatest leader of all times and peoples, illiteracy was practically eliminated and the heavy, chemical industry was created practically from scratch. But all the same, the average education of a conscript in the USSR was LOWER that in the USA, England and Germany. During the Korean War, problems with the M14 did not arise even among poorly educated blacks recruits. The same blacks recruits easily handled M1919.

The breakdowns of SVT were mostly related to the quality of production .. and care naturally .. Never in my life have I seen the use of AK in the function of a "pencil" ..

          Dear sir. (This is how I address you because I am not going to call you "Lord", unfortunately we have not been "comrades" since 1991, when you had a counter-revolutionary coup). I didn’t speak about "Gaps" (but also large tolerances). I talked about: a) A thin trunk, which DOES NOT HAVE sufficient rigidity, and sways like a sausage when fired). b) A thin-walled and insufficiently rigid receiver (which, when fired, twists and drives). c) The heavy bolt group, which also does not help the accuracy. d) anemic bullet, which does not have the penetration required in modern combat.

          The same very ancient Galil covers any of your remakes in accuracy by 30-50 percent. Why? Rigid receiver and slightly thicker barrel. Why are both Beretta AR70 / 90 and FN / FNS also superior in accuracy to AK74 in all its incarnations? After all, they, inside, are practically the same Kalash? Because the barrel is thicker (and therefore more rigid) and the receiver is more rigid. And it's not about the tolerances / clearances, but about the rigidity of the Barrel + receiver complex.

          I have both the Vepr in the 5.45x39 caliber and the Saiga in the same caliber. Only the saiga is exactly - AK, and the boar, he has a receiver and a half times thicker, and a machine gun barrel. Well, the difference in accuracy is 2.5 times when shooting Barnaul.
          One of the "secrets" of the accuracy of the M16 and its derivatives is not only high tolerances and precise fit, but a banal thick barrel (on A2, A3, and A4), which reaches 0.75 inches in diameter, but also a very rigid receiver (even though from aircraft aluminum). Watch the video in slow motion how the AK twists and talks, and how LESS does the M16 twist and talk. I'm not talking about the power of the cartridge. Personally, I can say that from 200-300m M16 does not break through the walls of houses in Iraq and Afghanistan. Masonry fences too. As far as I know, the power of 5.45x39 is even less (hence the small recoil impulse, miracles do not happen). That is why our Army is returning to the concept of the Battle Rifle chambered for the powerful 6.8 cartridge, which will be even more powerful than the 7.62x51NATO, instead of the assault cartridge.

          In the USA, when they buy a rifle, people are immediately divided into TWO camps. Those who are READY TO TAKE CARE of weapons, they buy AP15. Those who are NOT ready or willing to buy AK. There was also the question of PRICE. For example, cheap Romanian AKs cost 350-400 bucks, the simplest AP15 was about 500-600. Those who wanted to spend less money took AK. To "at least something" was. Ak on the US civilian market is exactly "At least something." There were high quality Arsenal Kalash. They were 800+ bucks. And they took them at times fewer people than took the AR-15. Because no one wanted to pay MORE for LESS FUSION. It is easier and cheaper to clean ARs than to buy Arsenalskie AKs.
          Then Saigi and Vepri appeared in the United States, and then Arsenalmen and Sentury Arms (Romanian shitty crap sellers) called out. Saiga - 450-400 bucks. Boar 550-600 bucks. Cheaper than ANY AR-15. THEN they began to be swept away, and then they were bought no more than the AR bought. Economy. when a Saiga with a chrome-plated barrel is 400 bucks, an alteration under a 30-charger magazine, if you do it yourself, another 60 bucks, and the crappy AR WITHOUT a chrome-plated barrel - 500 bucks, then yes, then and only then they took a LOT of Kalash. Then Saigi was banned. Their prices soared and again began to buy more AP15x. Because the Boar, although the same in price as a more or less normal ARC, AR is easier and more convenient. And when Vepri was banned, the sales of KALASHES fell again. There are now several sources of Kalash in the USA. Sentury Arms - more or less shitty WASR (WASR). Arsenal USA - magnificent Bulgarian Kalashs for 1300 bucks (the price is one and a half AP15, they are bought a little). Serbian ZASTAVA ARMZ ZPAP M70 (7.62x39) ZPAP M90 (5.56x45), these for 1100-1200 dollars. If your hands are not growing out of a dupa, then a normal AP15, even with a gas piston system, can be collected for 800 bucks. With a chrome-plated barrel. The barrel is 250 bucks. The lower receiver is 250 bucks. Top 100 bucks. Gas-piston system Adams Arms 200 bucks with a bolt group. If you search you can find cheaper
          Your statement that "ARs do not take, but prefer Kalash" is FALSE. Kalash was preferred (and even then not very much), when for the price of 2x more or less normal AP15 it was possible to buy 3 saigas. And with all prices being equal, Americans prefer ARCs.
          For a 50 year old Kalash in good condition, you will get $ 1500 in the USA. WHERE do you get that nonsense that you carry?
          https://www.youtube.com/watch?v=HGivoWD9OvQ вот вам ваш хвалёный АК74. Гнётся как вермишелька.
          https://www.youtube.com/watch?v=PEBMlfhlxYg АР15, тоже гнётся. Но в разы меньше. Ну и кучность соответсвует. АР15 в полтора - два раза кучнее чем средний АК74 или ТОНКОСТВОЛЬНАЯ Сайга.

          By the way, T.N. SAIGA M. With a machine-gun Veprevsky barrel and a weighted receiver. Well, the accuracy, of course, has increased. The problem of AK accuracy is not a tolerance, but an overly thin barrel and an overly light receiver.,

Economy. when a Saiga with a chrome-plated barrel is 400 bucks, an alteration under a 30-charger magazine, if you do it yourself, another 60 bucks, and the crappy AR WITHOUT a chrome-plated barrel - 500 bucks, then yes, then and only then they took a LOT of Kalash. Then Saigi was banned. Their prices soared and again began to buy more AP15x. Because the Boar, although the same in price as a more or less normal ARC, AR is easier and more convenient. And when Vepri was banned, the sales of KALASHES fell again. There are now several sources of Kalash in the USA. Sentury Arms - more or less shitty WASR (WASR). Arsenal USA - magnificent Bulgarian Kalashs for 1300 bucks (the price is one and a half AP15, they are bought a little). Serbian ZASTAVA ARMZ ZPAP M70 (7.62x39) ZPAP M90 (5.56x45), these for 1100-1200 dollars. If your hands are not growing out of a dupa, then a normal AP15, even with a gas piston system, can be collected for 800 bucks. With a chrome-plated barrel. The barrel is 250 bucks. The lower receiver is 250 bucks. Top 100 bucks. Gas-piston system Adams Arms 200 bucks with a bolt group. If you search you can find cheaper
            Your statement that "ARs do not take, but prefer Kalash" is FALSE. Kalash was preferred (and even then not very much), when for the price of 2x more or less normal AP15 it was possible to buy 3 saigas. And with all prices being equal, Americans prefer ARCs.
            For a 50 year old Kalash in good condition, you will get $ 1500 in the USA. WHERE do you get that nonsense that you carry?
            https://www.youtube.com/watch?v=HGivoWD9OvQ вот вам ваш хвалёный АК74. Гнётся как вермишелька.
            https://www.youtube.com/watch?v=PEBMlfhlxYg АР15, тоже гнётся. Но в разы меньше. Ну и кучность соответсвует. АР15 в полтора - два раза кучнее чем средний АК74 или ТОНКОСТВОЛЬНАЯ Сайга.

            By the way, T.N. SAIGA M. With a machine-gun Veprevsky barrel and a weighted receiver. Well, the accuracy, of course, has increased. The problem of AK accuracy is not a tolerance, but an overly thin barrel and an overly light receiver.,

            Where did you read about the thin barrel? You shove this thin trunk everywhere.

              I haven't read about a thin barrel. I saw him, since I have a boar, a saiga, an NHM91, and a ZPAP M90. And I have every chance to compare the Saiga heap 5.56, Vepr 5.56, ZPAP M90 (also 5.56) and AP15 (also 5.56). Barrel diameter on AP15 -0.75 "= 19.5mm. The barrel diameter on the AK74 / saiga is 0.592 inches, that is, 15.02mm. The larger the diameter of the trunk, the greater its RIGIDITY (all other things being equal). The less it will "wriggle" when firing, the slower it will heat up. Learn physics, material strength is a great thing. Links to the video have already been dropped. You can search for AK-74 barrel harmonics. Google to help you.

              Since you do not know about the effect of the thickness of the WALLS of the barrel on its stiffness, I assume that you are a pure humanist ... About such a subject as physics, thermodynamics, and God forbid, you haven’t even heard of strength materials. As Colonel Schroeder said about Free Determinant Marek, "What did you do before the war? Studied classical philosophy? So it’s a drunken intellectual. That’s definitely a classic case."

                  I am explaining this to you because you clearly do not understand the influence of the stiffness of the barrel and the barrel body on the ACCURACY. You know, diplomas are for sale. In underground passages and in the metro. Especially in post-Soviet Russia, Ukraine, etc., etc. Do you know how in the joke "Well, where did you steal your driving license?" "Eh, the citizen is the beginner, why did you steal it? What if I stole something from a Georgian Saraza? I didn't steal a license, I honestly bought them in an underground passage." Many people get their diplomas this way. Then they clearly do not understand that if two barrels are both 16.3 "inches long (on the AK74). But one barrel with a diameter of .59", and the second barrel with a diameter of .75 ", then WITH ALL OTHER EQUALS (that is, the same steel, and the same coating barrel bore), barrel number two will have greater RIGIDITY, and if so, and PUSH.
                  And I will explain to the "architects" that the barrel does not shoot by itself, it is attached in one way or another to the receiver. And the less the RIGIDITY of the receiver, the less TICKNESS the weapon will have. For example. Saiga M, has a receiver with a thickness of 1.5 mm. On VEPRA, in addition to the thickness of the receiver, there are special "reinforcements" (I honestly don't know what to call them in Russian), on the sides of the receiver, like on the RPK, which make the Vepr's receiver more rigid and less prone to vibrations and "wobbling" when firing ( see the video link to which I gave).

                  In all fairness, any weapon, including the M16, "wobbles" when firing (see slow motion). Another thing is HOW MUCH it "twists" (twists and warps in English). Saiga M, and, especially Vepr, DO NOT YEAR in the accuracy of the average AP15. (not the cheapest). But the payment for this is more weight than for the AP15 with an equivalent barrel length (for civilian AP15 it is either 16 "- for AK74 / saiga - 16.3", emnip, or 20 ", for boar and saiga M - 20.5"). It is worth noting that the AP15 with a barrel length of 18 inches is common in the USA. I do not compare them, since neither wild boar nor saiga with a long trunk of 18 inches were produced.

                  But then I have Galil, or rather a clone made in the USA based on a real Israeli receiver from Galil. With a barrel length of 18 "and a barrel diameter of .625". Galil LESS in the accuracy of the boar, is approximately equal to Saiga M, and surpasses the usual Saiga. Although, inside, it's the same AK. Why? And because Galil has a milled receiver, more rigid than a stamped receiver on a regular saiga 1mm thick. And yes, a thicker barrel. On my galil it is cold forged, made of 4150 steel, chrome-plated, with a twist rate of 1: 9 inches (the same as on Saiga M and Vepr). This, by the way, is the difference between Galilas made in the USA - the step of rifling is 1: 9. On the original Galilas it is 1:12, the same as on the early M16 models. In modern TRUE Israelite galilas, it is 1: 7. The same as on the US Army M4.

                  Unfortunately, I don't have FNC to compare with it. According to reviews, the FNC is more heaped than the AK74.

                  The ACCURACY of the system is provided, among other factors, by the RIGIDITY of the system, as far as it is susceptible to dynamic and thermal deformations during firing. Weapons can be great fit and very ACCURATE, but lose accuracy very quickly when fired quickly. And due to the TEMPORARY deformation (warping) of all weapons when firing, and due to the rapid heating of the barrel.

                  I apologize in advance for the possibly clumsy Russian language, I learned all this terminology in ENGLISH, so what I say is a literal translation from English, which may have turned out to be clumsy. Look for videos on youtube for AK barrel harmonics, and AR barrel harmonics. You will just see it clearly.

                  Any weapon is a set of compromises. AK-74 is not heavy, reliable, not very heap. M4, even lighter, more heaped, but not particularly reliable. Boar, heavy, reliable, heap. Match AR15. In size, like a boar, but lighter, it is distinguished by high accuracy (much less than 1 MOA with good ammunition, 0.75 MOA is NOT a record for such rifles), but rather capricious and very sensitive to the quality of ammunition.

                  At one time I wanted to collect myself a match AP15. Collected mostly Spike Tactical parts. When I came to buy a barrel, I was asked, "What kind of ammunition will you use?" want. Get yourself a regular, chrome-plated HBAR from FN, and you will be happy.

          Oh well. The 5.56 NATO cartridge is more powerful than the 5.45x39, we did not have enough penetration 5.56 NATO in Iraq or Afghanistan, even a simple brickwork of 1 brick from 300 meters does not penetrate. There were more than one cases when they fired at us from old Enfields and Mauser, from 300-400 meters (they just fired at the convoy or patrol, according to the principle "maybe we'll hit something), but we couldn't get them. That is why our The army is now seriously working on the transition to a more powerful cartridge. 6.8. With ballistics and power even higher than 7.62x51. We are returning to the "Battle Rifle" concept with a full-fledged rifle cartridge. That is, based on the experience of the Iraqi and Afghan wars, the American army is returning to self-loading rifles chambered for a powerful cartridge, which many predicted when they adopted the M16, and then the M4.

          And the difference between M16 and M16A4 is much more than picattini bars. Changed the steel from which the barrel is made. The pitch of the rifling, the "feeding ramp" was changed (I don't know how to say in Russian), the gas system was slightly changed, the diameter of the gas hole in the barrel was increased. M4 - there is a different gas system. By the way, in Iraq, I was given exactly the M16A2, I, as a doctor, did not clean at home, I sat outside and was engaged in fire support, and worked as a DMR. To be honest, the M16A2 is more reliable than the M4A1 :-). Why? And because when the system was made, the whole system was tied to pressure, and other factors (dwell time, for example) that are unique to the rifle length gas system (rifle gas system, with a long gas tube). When they started to be smart with a carbine, they changed everything. Naturally, the reliability has dropped, and the wear of the parts has increased, since the carbine operates under high gas pressure in the system.

        Yeah, "more precisely" just for some reason, most automatic rifles in 5.56 have greater accuracy than AK in 5.45 caliber. All these "remakes" are like a 50 year old woman dressed in new outfits. All these planks of picattini, pischmatini do not change ANYTHING in the weapon. The barrel is thin and does not have sufficient rigidity, the receiver drives when firing (see the video with a slow-motion camera and compare with the M4). Inside, a heavy "bolt carrier" flies here and there, which does not help the accuracy and accuracy either.
        Nothing new 200th series, except for the wound picattini rails, practically did not give. The same thin barrel, the same thin receiver, and the same heavy bolt action. It's like a 50 year old woman trying to hide her age under layers of makeup. Yeah, the recoil momentum is small, as well as the penetration ability of the bullet. Shoot with 5.6 (aka 22LR) - there the recoil momentum is even less.

        Here I partially disagree with you. By themselves, picatinny rails do not change anything, it's true. But it is necessary to massively install the corresponding sights on them and we get a sharp improvement in the results. Moreover, the less trained the shooter, the better the results.

    It's sad to look at all this ... They invented a bunch of names, but in fact they hung picatinny bars on the AK-74, put a pistol grip and an adjustable (if only in three positions) buttstock. Which at the 200th folds even clumsily, not quite tightly fitting to the body on the left. This of course "dramatically improved" the characteristics of the AK-74. For two decades, a huge team received a salary to give birth to this? Yes, the trunk of the 200 was hung out - a breakthrough. Which was delayed, however, for 15 years. AK-12/15 has no aesthetics, only one deformity. Only PP-20 pleases, and that is probably because some non-main Kalashnikov team developed it. The barrel when firing 7,62 in both 103 and 203 throws up no worse than that of the AK, comparable to the AKM. But the presenter learned to switch the fuse and toss the butt with his brutal left hand. What are the tolerances for the manufacture of barrels, comrades, have you changed the machine park? As you did the barrels with cold forging, so you do. Kalashnikov is Avtovaz in the arms industry.

      the stock is adjustable in 4 positions, and the adjustable stock improves the use of the machine
      in my opinion the AK-12 looks aesthetically beautiful, but I think it doesn't matter for a weapon
      PP-20 is being developed exactly by the Kalashnikov team, I don't understand why humiliate workers and engineers, they work
      if in the presenter's opinion it is more convenient to switch this way, why not

    Further proof that the new weapon can shoot forward and backward. When shooting backward, you need to move your head to the side, so that the bullet does not ricochet about the eye and kill the one lying in the trench nearby. Still, it is much safer when the weapon fires only in one direction, Baron Munchausen agreed with this.

      There is a lot of talk about the lack of rigidity of the barrel, I think if the gas outlet pipe from one end is stamped on dead to the gas outlet chamber, and on the other in the same way to the block of the aiming bar, then a structure similar to a truss will turn out and its rigidity in the vertical plane will multiply without increasing weight, it will be even tougher if we connect some kind of rod and the gas chamber with the front sight.

        there is something else, a piston runs through the gas tube, creating additional vibrations (in addition to those created by a bullet passing through the barrel), this does not affect the accuracy and accuracy in the best way. By the way, in the USA there is a civilian rifle MINI 14, which appeared many times in one of my favorite TV series "The A Team". So, the M14 at one time had a very thin barrel, 0.55 "just like the AK74. Its accuracy was about the same as that of the AK74 - 4-5MOA. So, a gadget was invented for it - HAR BAR, (and several more similar accu-strat, mo-rod) Thick-walled tube made of aviation aluminum, screwed at one end to the barrel, the other to the sleeve on the front of the stock (I don’t know how to say in Russian).
        Accuracy increased 1.5-2 times. Firstly, this tube served as a radiator that receives heat from the barrel, and secondly, it stabilized the barrel.
        About 12 years ago, Ruger released a new variant of the Mini14, with a .625-inch barrel. Accuracy has risen, and with gadgets like Akkyu Strat or Har Bar, the accuracy of the mini 14 has already been compared to the accuracy of the average AP15.
        By the way, here the company is engaged in exactly what turns MINI14 into DMR rifles. The first thing they do? They put a heavy barrel. from 0.75 "in diameter and above. Well, the guaranteed accuracy directly depends on the diameter / thickness of the barrel. Naturally, other modifications are also offered.
        https://www.ruger-mini-14-firearms.com/ruger_mini_prices.php

        By the way, I like the Mini14 much more than the AP15. It just lies more comfortably in the hand and is more "prickly". Why didn't I buy one? They have chrome-free and even nitride-free barrels. Such trunks are killed very quickly.
