Behold, I am doing new; now it will appear; don't you want to know that too?
Exodus 43: 19

Weapon and firms. Here, on the pages of VO, it has already been told about the pistol and rifles of Mr. Savage, nicknamed Savage in Russia. So this time we will not repeat either his biography or all other information from the activities of his company. You type in the search engine: “Pistol / rifle Savage. Military Review. Shpakovsky "and everything opens up to you. They talked about the present day of this company, and about what interesting rifles it produces today. And it produces all the same AR-15, as many other firms, competing with each other - who surpasses whom.

And the question is, what new can be added to the “arch” so that it, in fact, remains an “arch”, but at the same time acquires some completely new consumer properties?

It is clear that we are not talking about covering all its details with gilding, decorating with Swarovski crystals or cutting a handle out of mammoth bone. Although personally, I would certainly make at least a couple of such rifles at my enterprise. “For men who have every conceivable AR-15”, “For women who dearly love AR-15” ... Freaks and show-offs have always been, are and will be, and this is the very “that” for them!

However, from the point of view of technology, this is much more complicated than simply decorating according to the principle of "expensive and rich". However, it was Savage Arms who managed to create the MSR15 Competition rifle for professional athletes who compete in practical shooting competitions.

The main innovation in this rifle is the barrel. Now, again, all kinds of barrels are not put on rifles. Made by cold forging, with longitudinal grooves that reduce weight without sacrificing strength, etc. etc. However, "Savazhtsy" and then said their weighty word. They fitted the MSR 15 Competition with a barrel made using the so-called "carbon" technology, the same as that of the Savage 110 UltraLite rifle. "Ultralight" translates as "ultralight" - it really weighs only 2,63 kg. For a hunting rifle, this decision is certainly justified. But for a semi-automatic, it looks like a somewhat unusual solution.

The carbon barrels were developed by PROOF Research and claims their advantage over conventional steel barrels is that they have better heat dissipation properties than classic steel barrels. The technology of their manufacture is as follows: carbon fibers are wound diagonally onto a steel leitner. That is, the barrel receives a braid, which allows you to achieve better heat dissipation when shooting, which comes from it. That is, the barrel itself becomes much lighter. Its durability does not decrease, and it cools better with intense fire!

It is interesting that "wire" barrels have been known for a long time. It was by this technology that the British made their gun barrels for their naval guns, which were on their battleships of the early twentieth century. A relatively thin leitner, then an outer tube, then a wire winding, then an outer tube, then two or three more windings in the breech - and here you have a finished gun. However, no one has ever made rifle barrels using this technology!

That is, an automatic rifle at a high rate of fire can fire without serious heating. In this case, the barrel itself is subject to less wear.

In addition, the "carbon" barrel reduced the weight of the MSR 15 Competition rifle to 2,63 kg, that is, it began to weigh the same as the "bolt" 110 UltraLite rifle.

Carbon fiber is carbon fiber, a material made up of fine filaments that are 5 to 10 microns in diameter and formed by carbon atoms. Carbon fibers have a low specific gravity, extremely low coefficient of thermal expansion, chemical inertness and strength. For the first time, such fibers were obtained by T. Edison in 1880, and was going to use them in incandescent lamps. Over time, materials based on carbon fibers have found the widest application in technology as heat-resistant insulating coatings, including rocket engines.

And this is how they shoot from it. The "carbon" barrel is clearly visible. Savage Arms Photos

For firing the rifle, cartridges of .223 Remington (5.56x45 mm) and .224 Valkyrie are used, with an initial speed of up to 1200 m / s.

The muzzle brake-compensator is removable, that is, it is installed on the thread. Therefore, instead of it, you can install some other muzzle device.

The MSR 15 Competition has an adjustable gas valve. Moreover, its location on the barrel does not at all interfere with the installation of various mechanical sighting devices on it, which can also be fixed on the Picatinny rail, through which the gas regulator stem passes.

The firm manufactures the receiver from forged 7075 grade aluminum with minimum tolerances.

The bolt has eight lugs and is mounted on a nickel-plated bolt carrier. Such a coating not only greatly facilitates the cleaning of the weapon, but also improves its sliding, thereby increasing the reliability of the rifle when firing. In general, all these minor improvements can well be applied to combat weapons. True, the same carbon fiber braid on the barrel can make it much more expensive. In principle, today technologies have reached the point that they allow almost all small arms, such as the same automatic rifle, to be made of carbon fiber. The only exception may be some important details. Such, for example, as a barrel, a bolt, a tube of a gas engine and ... springs in the trigger. All other parts can be made of plastic today, which will greatly reduce the weight of the weapon, without reducing its strength. And less weight means less fatigue of a soldier and ... more ammunition, which he can take with him with the same weight of his load.

True, today the high demand for carbon fiber has led to its sharp rise in price. It is painfully used in many areas. It got to the point that they began to add it to concrete, the operational properties of which naturally increased from this, as well as its price!

There is the MSR 15 Competition and clearly sporting "modifications", although they may well be used on military weapons. First of all, this is the cone-shaped magazine neck expanding from top to bottom, which facilitates loading, and also an additional bolt cocking handle, installed on the left.


The T-handle is a tradition. Savage Arms Photos

Moreover, the rifle also retains the traditional T-shaped grip at the rear of the upper receiver. That is, this rifle is convenient to use for both right-handers and left-handers, and the latter does not need to reinstall or adjust anything on it - the designers took care of this in advance. By the way, again, such a solution is quite applicable to military weapons. After all, the weight of the rifle is very small, so it cannot be assumed that it greatly increased it. But the grip on the left added very much to the convenience of working with the rifle!

The scopes on the MSR 15 Competition are supposed to be used mainly optical, and for their attachment the upper part of the upper receiver was made in the form of a ready-made Picatinny rail.

The MSR 15 Competition forend is made of aluminum and has M-lock slots for attaching various accessories. On the left handguard there is a bright red socket for a quick-detachable sling swivel for a rifle belt. For the rear sling swivel, the socket is also in a red ring in front of the butt tube. So here, too, we see an example of well thought out ergonomics and concern for the convenience of the shooter.

The rifle stock is traditionally taken from the most venerable manufacturer of gun stocks and other accessories - the Magpul company.


Magpool is forever too! Savage Arms Photos

That is, Savage Аrms did everything to turn the most ordinary "arch" into a sporting rifle of the XXI century, which does not require absolutely any refinement "to mind". Well, the use of a barrel with a carbon sheath made it possible not only to improve the accuracy of shooting from it even in conditions of very intense fire (which is just typical for practical shooting competitions), but also to reduce its weight without sacrificing strength. Well, what of all these innovations (and how soon) will migrate to new models of military weapons, we will sooner or later find out. And maybe even earlier than we think today!

      The world of "steel, carbon and CFRP" is futuristic, but not mine! I am for the old - "iron and wood". On the level of feeling, habit and aesthetics, rough plastic is inferior to smooth wood. Especially if it is not coated with varnish, but impregnated with oil. Even leaning your cheek against the old Izhik stock, you do not feel the chemical smell of carbon fiber, but at home.
      Well, somewhere like that, perhaps "lordship" or a habit, but I agree to put up with ebonite, plastic and bone, only on a short barrel. For a long-barreled one, whenever possible, I always try to make a wooden body kit. However, for the PM I have three or four wooden handles. Two in oil and two in varnish.

            Namesake, I didn’t have a chance to shoot from the “Makar”. In theory, the cheeks should: not slip in a sweaty palm. How much wood is better than plastic, I cannot compare. Perhaps, purely visually, the wooden ones are prettier.

          No, for my own pleasure I make a "wooden body kit" (stocks, butts, handles) mainly for pneumatic weapons.
          In fact, it looks like this. For a thousand wooden or a bottle of vodka, I buy dead pneumatics. I restore iron and make a stock, a stock, a case if necessary. Then I give my daughter or children of friends or acquaintances.

          It turns out somewhere like this.

        The study showed that the orderly security forces MANDATORY have weapons with wooden parts, moreover, from LIGHT WOOD. Psychologically, the level of aggressiveness decreases, while trust increases. "My police take care of me!" Black - only for counter-terrorist units. I always remember the memories of a guy who was taken hostage in a Soviet school in 1981. When his two villains were released from the classroom and he went out into the corridor, there was an Alpha fighter in all black. And he was so scary that the guy WAS ALWAYS NOT STEPING BACK!

          And where does this "cool bike" come from? Especially considering that usually police officers carry service pistols ... in a holster, where it is not particularly visible, from what material the pistol grip cheeks.

Here you have to write so that every word, every number would have a source.

I can't put numbers 1,2,120 for every fact and figure, you can't read it. So be satisfied that this is "true." In addition, we are not talking about pistols, we are talking exclusively about long-barreled weapons!

          Doesn't the tests provide for dropping any weapon onto concrete from a height of three meters? Is this the standard? And somehow she passed this test ... And the freezing in the cell. I saw this photo myself. And since there was a freeze, then there was a drop ...

            I'm not sure about 3 meters. Is not a fact. But, in any case, a strength test is provided. Moreover, the Soviet test standard is unlikely to withstand both M16 and AUG.
            I remembered a case about strength tests ...
            It was like that in 1978, in my opinion. My classmate bought a watch, SEIKO, water-resistant, shock-proof from the blacksmiths. They sat down to "wash" them with a company.
            Word for word, after the second bottle of vodka and the statements of the comrades about the dubious shockproof strength of the "Japanese", the owner (CCM in classic wrestling in heavy) takes off his watch and shouting "Let them have nothing, they are shockproof" I brush them against the wall. Only the glass arrows fell down.
            Everyone sobered up at once. I explain to him what shockproof means - this is when the watch collides from a flat surface from a height of 1 m onto a flat concrete surface. I don't know how much "g" he gave to the watch, but there was a pothole in the wall.
            I didn't say what exactly happened to AUG from a friend, but he bought a new plastic case for her.

      Once I read on one of the Israeli forums a big discussion about the AK and M16. I liked one comment the most.
      In Israel, all those who have served in the army must go through a training camp every year. And if the regular personnel are armed with new small arms, then the reservists are given everything used from the warehouses. And from this old, as he writes, rubbish has to be shot.
      And the cases of destruction of the old M16 in general are not uncommon. And its output:
      And after 30 years AK remains AK, and M16 turns into a pile of aluminum trash ...

      By the way, the only automatic rifle in the world equipped with a manual forced closing system. Only AR-ki are equipped with such a "miracle".

      And one more fact. The special forces group that took on Saddam Hussein was armed exclusively with AKs. They did not dare to take their M4 with them.

        I went on a business trip to Israel in 2000, just at the beginning of the 2nd intifada. There were a lot of servicemen with weapons on the streets, and Jerusalem is generally chock-full. In Jerusalem, everyone is from M-16. Naturally, against the background of such pictures, the conversation with the locals about weapons started, and the topic "AK versus M-16" was not bypassed.

        As far as I understand, the army then preferred Galil and were strongly opposed to the M-16, which they stubbornly tried to push through. And massively at that time, M-16s entered only the police units.

        Including, all these discussions are a post factum phenomenon. After the M-16 was imposed on Israel en masse.

          That's right! It's just that the Israeli government has calculated that it is cheaper: to receive M16 for free from the States as military aid, or to produce Galilas themselves. We stopped at the first one. Although the military was against the "American" because of its sensitivity to pollution - there is plenty of fine sand in the "promised land". And the police still work in more comfortable conditions than the army.

            And again, where are the proofs about "special sensitivity to pollution", which M16 / AR-15 does not suffer from the word "at all". By the way, at one time, due to the sensitivity to pollution, the same Israel Defense Forces refused from FN FAL. This story really took place.
            As for the "Galil" ... yes, there is no special reverence for them in the Israeli military. From the word "absolutely". The most striking proof of this is that Galil was removed from service (except for some police units, where it remained "on a leftover basis"), and its new version ACE was not accepted into service. Instead, they created first the Tavor TAR, then the Tavor X95, the design of which has nothing to do with the AK / Galil.

              Galil was removed from service not because he is bad. It has proven itself just very well.

              The main disadvantage of Galil is the receiver, milled from steel. With all that it implies. The ACE version got rid of excess weight, but still remained too expensive.

              Including, the main reason for the removal of Galil from service is purely economic.

              P.S. And by the way, this is also not entirely correct:

                  Well, about the "gift" you slightly ignored or expressed incorrectly, but 10 times cheaper than Galil, it is really almost for nothing.

                  The funny thing is that with Tavor TAR the dance began on the same rake. Compared to the M16, this is also very expensive, and in terms of automation it is closer to the AK.

                    Let's say, figuratively speaking. Yes, you yourself understood it. drinks

                    As far as I remember, the first batches of rifles (nothing was said about the specific quantity) were actually delivered free of charge, so to speak, for seed. As part of the US military aid to Israel, but in the future, of course, all this was paid for. But Galil cost the Israeli budget, of course, more expensive than the "American", especially taking into account the preferential targeted loans provided by the Americans to the Israelis.

                    With Tavor, the IMI firm, I suppose, just tried to bite off a piece of Israel's military budget. And get into the international arms market.
                    While they managed to shove their "suitcase" into the Ukraine - the Vinnitsa Fort established a screwdriver assembly of TAVORs. With fanfare, the spetsura march with them at the holiday parades.

              Last week, electronic media circulated negative assessments of American rifles, which are "often jammed in the desert," given by the occupying forces in Iraq. The Americans say that the AK-47 is not only more durable than the American M-16, but also surpasses it in power and is also easier to handle.

              The Kalashnikov assault rifle is an ultra-reliable weapon that was created for war. This was stated by the veteran of the special forces of the US Armed Forces Brandon Tyler Webb in the publication of the publication SOFREP.

              According to him, in Afghanistan and Iraq, the US military preferred to use the Kalashnikov assault rifle instead of the Colt M4.
              “There is a reason why we used the AK-74. This damn thing continues to shoot even after salt water and is not afraid of sand, ”said Webb.
              He also added that the M4 breaks down every time it comes into contact with the sand, so the US military has to use waterproof bags to arrive on the battlefield with workable weapons.
              Webb recalled that the AK-74 is an upgraded version of the AK-47 assault rifle. The updated rifle has a higher firing accuracy and reliability, thanks to which the Russian machine gun works in any conditions.
              “He passed the test of the Apocalypse for me,” he stressed.
              According to Webb, if he had to choose between the M4 and the AK-74, he would have chosen the Russian assault rifle without hesitation, since it is distinguished by its simplicity, reliability and high destructive power.

              where are the proofs about "special sensitivity to pollution", which M16 / AR-15 does not suffer from the word "at all"


              It's not good to juggle. Your opponent doesn't have the word "especially". And you put the whole phrase in quotation marks as a quote.

              And the fact that M16 is more sensitive to pollution than AK naturally follows from a significant difference in the energy of moving parts due to differences in the automation scheme. The fact that this is a double-edged sword is known not only to experts. It makes no sense to talk about this topic.

              Well, there are also purely design features and all sorts of "little things". So, I have never come across information about a jammed magazine at AK, but on the M16 it's easy, there are enough materials in the Internet. Etc.

        And one more fact. The special forces group that took on Saddam Hussein was armed exclusively with AKs. They did not dare to take their M4 with them.

        Will there be any proofs for this "cool story"?
        By the way, the only automatic rifle in the world equipped with a manual forced closing system. Only AR-ki are equipped with such a "miracle".

        True, there was no closer on the AR-10, and on the "Armalaytovsky" production AR-15, and even on the first XM-16s. Because there is actually no constructive need for it.
        This detail appeared simply because of the usual general's joke. In the 1940s - 1950s, the US Army was armed with the Garanda M1 self-loading rifle, a feature of which was a rather specific batch loading system for a non-removable magazine. So, so that the bolt (which came into motion after loading the store) does not pinch a finger, American soldiers acquired the habit of holding the bolt handle while loading (in Garand rifles (at least M1, at least M14, at least "Mini-14" it is rigidly connected to the bolt carrier ) - only when the handle was released, sometimes the bolt did not want to go forward and send the cartridge into the chamber.This was not a particular problem - the bolt handle was pushed forward once or twice with the palm, and everything worked fine.
        Actually, this is where the special wishes of the American generals "what if you have to manually close the bolt", which came from such a need on the M1 rifles. Since the American generals already had the experience of sabotaging the adoption of "anything other than the Garand system" for far-fetched reasons, they decided to simply add the notorious closer to the design, making the rifle heavier by 100-150 or so grams.

      I liked the idea of ​​the carbon barrel better. Remember I once wrote about the multi-barreled rifle of the future? And they wrote to me that the steel block of barrels would be heavy. Well, if the weight is reduced by 69% with the same strength? That is, the barrel no longer weighs 1 kg, but 300 g. 2,7 kg will weigh a block of 9 barrels. 150 g electronics from Israel. Another 1 kg - plastic handles ... Here is a multi-barreled rifle of the future weighing with AKM. Progress does not stand still!

        I liked the idea of ​​the carbon barrel better.

        Combined from different materials, or twisted from a rod (reinforced) trunks have a long history. At a glance, the "leather shoe of the Swedish king" and the "Parot" cannon during the Civil War in the USA.
        I honestly don’t know whether it will be pampering behind the carbon barrels, but I doubt it for the mass armament of the army. Especially knowing the conscript (conscript), who in the third month of service, having believed in the versatility of his Kalash, tries to dig into his nose and open a can of conservatives. How strong the carbon barrel will be in melee, I also doubt. In addition, even professionals use AK to overcome obstacles. With the same Vintorez or M16, such manipulations are impossible.
        Well, back to hand-to-hand combat. Even by the feeling of a “good club”, PPSh evokes more confident feelings than AK! No wonder the latter was added a bayonet knife. That the head of an adversary or a carbon barrel will be stronger is an open question, but even without this, with weapons in the army, pardon the pun, they are at war. That is, they drop, fall, stumble over it, and so on. Even aircraft-grade aluminum dies in the field in the third week from such treatment.
        Okay, let's see what happens tomorrow.

        Greetings. Unfortunately, the "carbon" barrel is not as good as the guys from PROOF Research say, and as the respected Vyacheslav Olegovich is broadcasting to us, however, let's go through the process of making the "carbon" barrel step by step:
        1. Steel liner made by any method available.
        2. A carbon fiber "sleeve" is made on a special mandrel, it is slightly larger in diameter than the outer diameter of the liner, because the Temperature Expansion Coefficient cannot be ignored, physics has not been canceled yet.
        3. The space between the liner and the carbon braid is filled with a thermosetting compound (what is a compound, and what is the difference between thermosetting and thermosetting polymers, I suppose there is no need to explain) under pressure, again in any convenient way for the manufacturer. The compound is needed to compensate for the TCR.
        4. The ends of the barrel are "put on" in metal couplings, usually of the same steel as the liner, although here the manufacturer's fantasy rules, some manage to stick aluminum here too ...
        Now about how it all works in the shooting process:
        1. At the moment of firing, the liner transfers heat from the powder gases to the nearest layer of our "carbon" barrel - the compound.
        2. The compound after a few shots heats up and "floats", ie. it simply melts, it's not for nothing that it is thermosetting, and the compound has no thermal conductivity, from the word at all.
        3. Finally, the heat from the burnt powder gases reaches the outer layer of our combined multilayer barrel - carbon fiber and through it quickly and quickly dissipates in the surrounding space, after all, carbon with its thermal conductivity is wow wink
        Thus, we have not a fast-cooling barrel, as the manufacturer promises to us, but a "slow-heating" barrel, i.e. with high thermal inertia, in other words, you can safely hold on to such a barrel with your bare hand for the first couple of series, but then .., especially after an intense training in the 10x10 mode, I do not recommend touching such a barrel to anyone .., well, at least for half an hour smile
        Well, and a bonus - after warming up the compound, the liner "floats" in it, which partly neutralizes the micro-oscillations of our barrel and increases the average firing accuracy, after the firing stops, the compound freezes ... after a while ... with all that it implies.
        Sincerely.

        Yeah, and cost as much as a hundred AKM.

        Actually, the idea of ​​a "carbon barrel" appeared a long time ago. And initially it was focused on precision weapons. First of all, the task was to reduce the level of vibrations and improve the accuracy, and not to reduce the weight. But the technology is very expensive for piece goods.

        That is, an automatic rifle at a high rate of fire can fire without serious heating. In this case, the barrel itself is subject to less wear.

        This is nonsense, the thermal conductivity of carbon fiber and carbon fiber reinforced plastics is an order of magnitude (and) worse than steel. Plus, composite barrels have only a low weight.

    nicknamed in Russia Savage

    Oh, and the whole Savage transferred to a new system based on 1C UT 11 then still beta in 2009 (I'm not talking about them, if anything, I just remembered the project, it took more than a year)

    In general, I don’t understand why to make it easier and so bother and increase the price? A decrease in mass, even in the presence of moving parts, buffer springs - increases the recoil when conducting automatic fire ... and even in sniper rifles ... increases the momentum ... No one has yet canceled Newton's third law belay
    I fired ~ 40 shots from the SVDU in 170 minutes - my shoulder started to hurt severely in the middle, even in armor! Moreover, it weighs more than 6 kg with a sight! Despite the fact that the mosinka is essentially a little more than 4 kg and at the same time does not have automation ...

    In the American project of the MCS tank, the barrel is made with a composite winding. The barrel is 1,5 times lighter.

    An excellent trunk, very light and heaped - I have a small Magnum Research with this. The liner, on which the synthetic material is wound - stainless steel, there is a special drill to parry the oscillation of the bullet when leaving the barrel, which increases the accuracy. I regret that at one time I did not buy 700 Remington with this - now, due to the sanctions, this is practically impossible.

      This is not entirely true, carbon is not fiberglass, if the rifle barrel has a dense graphite winding, then there can be no talk of any thermal insulation, thermal conductivity

        You are mistaken, the "closer" appeared precisely at the request of the army generals and also on the XM16. Its presence has nothing to do with the problems of early XM16s in Vietnam.
        On the same FN FAL, the cocking handle is not connected in any way with the bolt carrier.
        And it never occurred to anyone to equip it with such a device.

        True, the absence of such a device on the FN FAL was one of the reasons why the same American generals turned the rifle at a previously held competition in favor of the M14 of the Garand design, which had the option to “close the bolt with your hand”.

          Yes, that's not the point. The Americans simply gave preference to their own, American, and nothing else. At first, the American lobby pushed its .308 cartridge as a NATO standard. And then they frantically began to look for weapons under it, moreover, it was American. The M14 as an assault rifle was not the best solution.

      that in Garand sometimes it was necessary to close the shutter almost from the foot
      \
      Well, the Garanda M1 rifle was a very reliable "machine" in general. The problem is in the batch loading and the habit of holding the shutter with your hand so that you do not hit your finger. After this, sometimes the bolt itself did not go forward, as usual, and then it was gently pushed once or twice by hand. The rifle worked fine after that.

    PROOF Research claims that their advantage over conventional steel barrels is that they have better heat dissipation characteristics than classic steel barrels.

    Of course, I take your word for it, but not to the same extent.
    And in rocketry, CFRPs are used to some extent as a structural material with low thermal conductivity. And materials of the UUKM type are generally like inserts into the nozzle throat.

    CFRPs have always been inferior in thermal conductivity to metals. - and as an engineer by training, I got into reference books.
    Thermal conductivity of CFRP 0,75-0,90 W / (m • K)
    Carbon (carbon fiber reinforced plastic) thermal conductivity
    from 0 to 030 W / mK
    or when translated into degrees C, it barely reaches 1 W / (m ° C) well, with some tweaks, 8 W / (m ° C)
    Even if the filler is metallized, the thermal conductivity will still be several tens of times worse than gun steel: we are looking at steel for barrels.
    steel 30XN2MFA thermal conductivity 35-36 W / (m ° C)

    Vyacheslav, does the manufacturer rub it on us?
    What can be used in CFRP filler, so that the thermal conductivity is higher than steel? Copper?
    In my opinion, the guys scoff.

        The fact that it is lighter - this is according to the characteristics of the material - is indisputable.
        Barrels with carbon fiber winding have been making for several decades - and only for high-precision (non-rapid-fire) weapons. Since the heat dissipation of carbon barrels for automatic weapons is not efficient enough.
        But how the thermal conductivity of CFRPs can be made better than that of steels is questionable.
        Even if you introduce a thin copper thread into the weaving and metallize the filler, this will not give better heat transfer - since the filler is phenolic resins of various combinations, in itself a good heat insulator.

      A long time ago in the magazine "Master Weapon" there was an article about a hunting rifle or a carbine with a barrel made of a relatively thin steel rail with a thread, it had a thick carbon fiber coating, while it was already argued that this coating promotes heat dissipation, how effectively it was not specified. Of course, ordinary carbon conducts heat worse than steel, but thermal insulation is not made from it, and then it must be borne in mind that the outer surface of the carbon casing is in contact with the surrounding air, and it is one and a half to two times larger than the inner surface in contact with the barrel (simply due to the thickness) if done external ribbing the difference will be three to four times. and then, from the technological point of rhenium, it is easier to separately make a thick-walled carbon casing and then stick it on the trunk of the rail, then you can make perforations in the walls of the casing and glue copper inserts into the holes, then grind from the inside and stick on the barrel, even if you just add copper to the resin sawdust, this will greatly increase the thermal conductivity. By the way, the thermal conductivity of graphite differs greatly in directions, the same applies to graphite fiber and we do not know what kind of weaving it is.

        Colleague, making a "ribbed" carbon casing is not easy, I would say it is doubtful. the fact is that carbon fiber does not tolerate kinks, that is, to break it is - hoo, but to break - none wink smile The only way to maintain strength with such a design is to add a binder, but here the uneven heat removal from the liner comes out, alas - in the version you proposed, the complexity of calculations and manufacturing increases exponentially, because besides the heat dissipation, there are other factors that have to be taken into account, for example - - mechanical strength of the barrel (it is because of it that the carbon fiber "casing" is wound crosswise at an angle of 45 ^ to the axis of the barrel) smile As for metal inclusions in the material of the composite barrel, it is better not to have a metal thread woven into the carbon casing (do not forget about the TCR smile ), and a metal filler in the compound layer between the liner and the carbon "casing", well, remembering the words of Academician Shipunov about the share of material in the final cost of the product, silver powder is best suited in this case. Sincerely.

    Great theme. It’s interesting how the barrel was made, apparently the gas outlet was made with a metal broadening, in general, if this barrel actually works like a steel one, then in combination with a lightweight kerrier from Company GK it is possible to reduce the weight of the system to 2.5 kg, which will greatly affect the performance.
