Automatic Remington ACR (Bushmaster ACR)

46
Over the past few years, a huge amount of accolades about the Bushmaster ACR machine has appeared. it weapon is an excellent example of the implementation of a modular design that allows not only changing the class of weapons by replacing individual parts, but also changing ammunition in a matter of minutes without special tools.

In general, calling the Bushmaster ACR weapon is not entirely correct. The fact is that such a name is applicable only to the civilian version of this product, and since more people have access to civilian weapons, the name of the weapon has accordingly taken root. The weapon variant for the military has the designation Remington ACR, and initially the machine gun was generally referred to as Magpul Masada ACWS.



Let's try to understand this confusion.

How did the machine Remington ACR (Bushmaster ACR)

It all started with the fact that Magpul decided to improve the design of the M16 to facilitate the maintenance of weapons, but everything grew into a more serious project, at least this version, which was followed in the company.

Automatic Remington ACR (Bushmaster ACR)In principle, this can be believed, as each person has come across a situation where the desire to improve something leads to the fact that you begin to understand the imperfection of individual nodes and how easy it is to eliminate other shortcomings that you did not pay attention to before. Do not fit in this stories Only one thing - through 4 a month after the start of the project, a new fully viable product was presented, ready for mass production.

It is possible, and this is only my guess, and not a fact. Magpul already had significant achievements in terms of new weapons, but there was not enough financial resources to complete the work. In this regard, I repeat once again, it may be that the money was taken to update the M16, which is a very promising direction in terms of return on profit, but this money was sent to complete the work on the new machine. And once again I repeat that this is just my guess.

Anyway, after 4 a month after the start of the modernization of the M16, a new Magpul Masada ACWS submachine gun appeared (if you translate an abbreviation, you get something like an “adaptive combat weapon system”). Or rather, not even an automaton, but a whole range of small arms consisting of 2 submachine guns chambered for 5,56x45 with 368, 257 barrel lengths and the designation Carbine and SQB; sniper rifle for the same ammunition with a barrel length of 457 millimeters and the designation SPR; automatic machine chambered for 7,62X39 with the designation AK. A manual machine gun chambered for the 7,62x51 cartridge appeared a bit later, although it can only be called a machine gun within the framework of the national classification of weapons. All this could easily be transformed from one to another with the help of interchangeable modules of which the weapon consists.

In 2008, the full result of the work of the designers of the company Magpul buys a license Bushmaster Firearms International. After a slight modernization of the weapon, which was a transfer of the loading handle, a new weapon appeared on the market under the name known to us - Bushmaster ACR.

In the civilian market there are options for weapons with barrel lengths 318, 268, 406, 457 millimeters. Moreover, the amount of ammunition for which the weapon can be adapted, namely the cartridges 5,56x45, 7,62x39, 6,8x43, 6,5x39, is significantly expanding, at the moment .300 AAS (7,62x35) has also been added to them. Given the popularity of weapons, this list may expand. It goes without saying that for the civilian market all weapons are deprived of the possibility of automatic fire.

Since the weapon very quickly proved that it could not only carry with well-known and credible samples, but also surpass them in certain characteristics, the military became interested in the machine gun. And here begins the confusion in Santa Barbara of American arms companies. The fact is that Bushmaster is part of the Freedom Group holding company, which includes Remington in all its guises. It is the company Remington and engaged in the supply of a modular system ACR in the US Army.

Thus, for the civilian market and for the army, weapons are offered by two different companies and money goes to different wallets, only one wallet in the right pocket, and the other in the left one.

It should be noted that the machine itself is well proven in Afghanistan, that is, with significant temperature drops and not the cleanest conditions.

The design of the machine Remington ACR (Bushmaster ACR)

Returning to the issue of upgrading the M16 for the 4 month, it should be noted separately that the final result can boast of an automation system different from the M16.

Automation weapons built around the removal of powder gases from the barrel with a short stroke of the gas piston and is virtually identical to that of the AR18. Automatic AR18, as they say, is widely known in narrow circles. Those who are addicted to firearms know the name “Widowing”, which the machine gun received due to its popularity in the IRA.

Despite the fact that the bolt and gas block of the weapon are represented by separate modules, each of them is easily disassembled for repair and maintenance. The same applies to the trigger mechanism.

There is a very interesting fact about the trigger mechanism of this weapon. This is the only element that distinguishes the civilian Bushmaster ACR from the army Remington ACR and is presented as a separate module. That is, in order to obtain military weapons, it is enough to replace only a separate module, which in the case of global hostilities can be useful if there is a shortage of weapons, which is unlikely of course, but still.

The controls are duplicated on both sides. The cocking handle can be installed both on the left and on the right side, or it can even be on both sides. But It is worth noting that during firing the handle moves, unlike all the same M16.

What is really quite useful is the presence of various options for the machine guns, the standard butt, by the way, is folded up and does not interfere with firing from a weapon, although the fire mode switch closes on one side. Given the widespread use of light armored vehicles by the US Army, it becomes unclear how a weapon with a fixed butt can be in service.

If we talk about the modularity and ease of operation of these weapons, then it should be noted that the designers coped with their initial official task - the weapon can be completely disassembled and assembled without additional devices. Even the barrel can be replaced “on the knee”, while at medium distances it will not be necessary to shoot the weapon - the deviations will be minor, even though the aiming devices are located on the receiver and forearm.

A separate "chip" of this machine is that its mechanisms can work without lubrication, but the manufacturer does not recommend to abandon the lubricant at all, it just needs a minimum. This is achieved thanks to the special coating of individual elements of weapons, which in principle is not new, and each manufacturer has its own composition and its own patented names with approximately the same performance characteristics as a result.

Often, you can find information about the incredible accuracy of this machine, comparable to the accuracy of a self-loading sniper rifle. Conversely, there is no secret in this, such a result is achieved by fitted details of the mechanisms of the weapon, and most importantly thanks to a high-quality trunk, whose channel is chrome-plated. It is even stated that the thickness of the chromium layer is three times thicker than that of the M4, which, in theory, should have a positive effect on durability. Speaking in numbers, this is the 0,5-1 corner minute by single shots. But these are the numbers that give the owners of these weapons, the manufacturer does not say anything about it.

Pros and cons of the Remington ACR (Bushmaster ACR)


The main advantage of this machine is its high resource and stable characteristics for each weapon, which is rarely found in any mass-produced product. The ability to adapt to specific needs, and most importantly to various ammunition, is also an indisputable plus. The “omnivorous nature” of weapons for ammunition from different manufacturers, ease of maintenance - all this is and should be present in any weapon, but for some reason the presence of this should be singled out separately as a virtue, and not as a matter of fact.

The main disadvantage of this machine is its cost. Of course, for each individual module, you can distinguish individual negative aspects, but the beauty of modularity is that if something is not pleasant or not comfortable, then this part simply changes to another and as a result you can assemble a weapon not only suitable for specific tasks, but also fully appropriate personal preferences arrow.

Conclusion

In the conclusion of the article about the Bushmaster ACR or Remington ACR machine, one cannot but touch upon the topic of pricing. It is very doubtful that in production this weapon will be twice as expensive as other common production models, and indeed it’s obviously not phenomenal, but just a little higher than in some other models. Despite this, the price tag of the machine is not at all slightly higher than that of the M4.

If we draw any conclusions on the design of the weapon, then we can say that there is nothing supernova in it, just the weapon is made qualitatively, not from scrap metal, with high accuracy and normal quality control.

It is impossible not to touch on the topic of modularity of weapons. For some reason, for most people, even the possibility of changing the trunk is absolutely unnecessary for the machine. And indeed, no one will carry with them interchangeable trunks of various lengths, much less change a long barrel to a shorter one when on the move, when you enter the room, for greater maneuverability. It is even doubtful that someone will change the same barrel immediately before the fighting, adapting the weapon for a particular situation. The main advantage of the modular system is that weapons are much cheaper in mass production.

You can take the simplest example. Suppose there is a machine gun, a light machine gun and an automatic sniper rifle of completely different designs. Every detail of such weapons must be done separately, and this is not only human-made and more workers, but also various production lines, or even completely different factories.

Now imagine that there is one receiver, which is completely the same for all three classes of weapons. There is a trigger mechanism that is the same for a machine gun and a machine gun. There is a bolt group which is suitable for both the sniper rifle and the machine gun. So the list is endless. As a result, instead of doing two or three different parts, you can make one the same.

Not least, and quick repair in field conditions, when of two, sometimes different, weapons with different breakdowns, you can assemble one complete, and you do not need to be for this master-gunsmith.

Even training in the maintenance of weapons, which is not fundamentally different from each other, is an indisputable plus of a modular system.
So modularity is not a huge amount of various unnecessary additions from the fact that money has nowhere to go. Modularity in a firearm is the ability to count and save money.

    I could not find in the article: The machine is sold in the form of 1 set of barrels and nozzles with a single base? at the price of 2-3 machines or how 1 machine with a single base for the price of 1 machine? that is, its advantages are understandable: if you are selling in sets, you can assemble a machine gun from a carbine and rifle, or anything else, if you have 1 assault rifle with a single base, then you can assemble a rifle from a carbine and rifle, for example, if the necessary details are intact. the cons are not clear: how much and how many times is it more expensive ??

    In the civilian version, Bushmaster spun in his hands. Qualitatively done, the balance is good, the descent is controversial but normal. option was chambered for 223 rem. But in 308 it seems to me that he finally can "Lala." It is felt that this caliber was originally laid down.

      not advertising - I watched the video cycle, how an American is testing freshly acquired trunks - so he had one thing on this topic:
      he fired at SCAR under .308, and Magpool Masad, also under .308.
      Then he changed the trunks, fired again, and so on.
      So, the STP deviation was really minimal.
      he himself was very surprised, he says - he used to think that this was an advertisement - it turned out not, indeed it is possible to shoot and fall after replacing the barrel, the bullets do not go into the "milk".
      Yes, the accuracy decreased by some percent, but not critical.

    It is not entirely clear how the shutter frame is made, it is too small. Does a pin stick out backwards? But there seems to be not much left of the M16. You can see the curtain and some models have a mine under the store. The curtain is only on the right, so the left-hander will have a sleeve in front of his nose to fly? The shutter with the shaft will give the effect of M16 in the mud, although there everything is done from one fluoroplastic. But not everyone has a mine - so that it would be customary for Amers to hammer up a store?
    A thick layer of chrome in the barrel probably raises the price, not by the cost of the metal, of course, but by the process technology. But not twice. And what kind of difference is not clear.
    Well, okay - gradually they will do the same AK and calm down. And planks open.

    It was inspired by a sort of Kipling: “West is West, and East is East ...” - “a machine gun is a machine gun, and a sniper rifle is a sniper rifle and they should never be together ... built on a“ single modular base ” ! " request... "a bolt group that is suitable for both a sniper rifle and a machine gun" is very interesting! smile , because the operational and technical requirements for them are radically different and you don’t need to be a master gunsmith to understand that any universal unit in its basic characteristics obviously loses to a highly specialized wink !
    What I absolutely agree with is the fact that a gas outlet with a rod is much more reliable than a rodless one.
    This submachine gun is so-so, it can be seen from which “family” it came out, “trendy” meshed and with large longitudinal slots in the “sophisticated” receiver, which will collect all the sand inside into a sandstorm and all the dirt when crawling on the ground ...
    About the stated sniper accuracy “I doubt very much however” and I don’t share the copyright enthusiasm, since any interchangeable (a priori assuming clearance in the connection) barrel “breathes” when fired and inevitably gives a range of hits!
    The increased thickness of the chrome coating of the bore does not contribute to its sniper accuracy, the best performance in this is not chrome trunks!
    PS This author’s passage, “it’s just a weapon made with high quality, not from scrap metal, with high accuracy and normal quality control,” I didn’t quite understand, this is a hint at YouTube “self-fingers” from Pakistan and Thailand, some domestic authors known to the author Are self-made “businesses” who “poorly” scattering their underground “bagpipes” from scrap metal, on their knees or some partisan workshops from the jungle trying to enter their global arms market to compete with the Bushmaster Remington? winked

A good machine gun and should have a quick change barrel (for Ultimax, the barrels also vary in length, depending on the purpose of a particular machine gun), and the quicker the change, the “better” (although, like, nobody has yet managed to surpass the speed of changing the barrel German MG-42 (MG-3)?)

      And what is the pressed barrel better than screwed in?
      In general, even on long-range sniper rifles, threaded-mounted barrels and nothing - somehow "without gaps" are made.
      I don’t see the slightest problem in the method of attachment, especially for quick-change barrels, they have been designing for a long time.
      Moreover, there is no question of more than the Marksman rifle (up to 1000 m) in the Remington ACR (Bushmaster ACR) complex - and 0.5-1 MO is an excellent result.

          Well, why not debate? How is an engineer with an engineer?
          I don’t see any problems in that the barrel is quick-detachable (the barrel runs at the same time as the chamber) or is mounted on a tapered or cylindrical thread to the bolt frame.

          Scheme SVT-40.
          Technologically, on a quick-release barrel, it’s even easier to arrange an exact tolerance for locking the shutter. And the strength characteristics of the fastening can be ensured at the level.
          The issues of ensuring the alignment of the sighting devices of the barrel group and those located on the slide frame is a matter of production culture and equipment accuracy.

            That's just the point, dear DimerVladimer, that the quick-detachable barrel differs in its fastening from the "screwed-in", even in the discussed "adaptable rifle" Bushmaster "ACR"Yes
            I know this well (both theoretically and in practice), but you still don’t (even the video review given by prosto_rgb didn’t bother to see and you didn’t see bushings with sector thread?). Therefore, although we are engineers, we are “sharpened” in different ways, alas, I can clearly see it from your post — the words in it are technically correct — everything seems to be “engineering”, but from a weapons point of view, yours, although would it be: “I don’t see problems in the fact that the barrel is quick-detachable (the barrel runs at the same time as the chamber) or is mounted on a tapered (?) or cylindrical thread to the bolt frame (to the receiver?).” - to put it mildly, amateurish “nonsense”, worse than the previous "twisted" trunk! winked
            You probably never held a machine gun with an interchangeable barrel in your hands or, at least, instructions on domestic PCs (PKM), SG (SGM) -43, like "mirror clearance (is this a term a sign?)" Is regulated in machine guns with interchangeable trunks do not know? winked
            The SVT-40 scheme you have given, regarding quick-change barrels, is completely inappropriate — in it the barrel was fastened to the receiver with a tight thread!
            Unfortunately, we are talking with you, in the subject under discussion, in different engineering languages, dear DimerVladimer, although on your posts in other Topvar.ru branches. I find you a pretty technically competent engineer and read your comments with interest. IMHO.

      I agree one hundred percent. In addition, any favorite change of trunks gives a shift of the point of impact from the aiming. For a machine gun, this is not fatal. For a machine gun or sniper, it is deadly.

      Nut should still be the difference. Production now and 50 years ago.
      Illustration - a mass Kalash for SA. All consignments of weapons passed acceptance. But through testing, it is possible to identify machines in the party that are worse and better. And here, the design itself involves the riveting of initially select automatic machines. Moreover, those that disassembling, dumping parts into a heap and assembling back, you get the same selective machine. Manufacturing with virtually no tolerances, such that parts 1 in 1 are similar to each other.
      The author is simply mistaken. This is what he writes.
      The main plus of the modular system is that in mass production weapons are much cheaper.

      Quite the contrary, ensuring the interchangeability of modules is a very high level of production. Details will have to be almost “cloned”. Modern fully automated equipment, premature replacement of consumables to ensure minimum tolerances. It is very expensive. Illustration - PPSh military assembly, which came up only two specially tailored exactly for him store. But it’s very cheap, women and children sharpened and stamped on worn-out equipment; again, the children assembled.

      The problem is rather in wear and tear during operation. Change modules 500 times and look at the result. On the other hand, time goes on and progress does not stand still. Perhaps some coatings are already able to survive this business without problems.

      So the author mentioned that the manufacturers themselves did not declare any sniper accuracy. It was announced by users of brand new machines. That's when the machines will not be completely new and a little worn, let them look again. Most likely, high accuracy at the beginning of operation is the result of "cloning" of parts during production.

      I do not agree.
      What prevents the provision of three centering surfaces of the barrel / bolt frame, which will ensure alignment of the sights on the barrel / bolt frame.

      What does the trunk breathe mean? I understand thermal warping. But when fired, the barrel, both on a threaded connection and on a quick-change, transfers the main loads from the bearing surface of the barrel, to the supporting surface of the bolt frame, for which there is a strength calculation.

        The barrel "breathes", that is, it doesn’t sit quite tightly in the receiver’s nest and when fired, at the enormous tensile-compression stresses developing at that moment (as well as heating the compound during firing), it receives additional degrees of freedom with all the ensuing consequences ... request
        But this is your hope (appeal) of the "strength calculation (which" will write everything off) "and the tendency to speak in a scientifically obvious way gives you a" theoretician ", unable to look into the essence of the phenomenon? smile After all, you probably know the “common saying (in technical circles) proverb” - “zero at the input, zero at the output” and that all “strength calculations” are made with certain conditional assumptions and only a practice-criterion of truth smile ?
        ЗЫ When firing, the "supporting surface of the barrel", under the action of the "main loads" arising, tends ("loaded") in the opposite direction from the "supporting surface" of the shutter and, associated with the shutter, of the shutter frame, somehow or whatever, in your opinion (how do you imagine the vectors of the loads arising from a shot?), no winked ?!

    Good old gas engine! Personally, I still like the German G-3 system, it’s nowhere easier and more reliable, moreover!

      Is this nostalgia for a NATO cartridge of 7,62 × 51 mm?
      Then it’s a much more modern HK 417 in this caliber.


      Nevertheless, the hydraulic compensator clearly contributes to more accurate shooting at medium distances.

          It is a normal kit for police actions. He arrived, walked for half an hour and shot, after which he left.

    Thus, for the civilian market and for the army, two different companies offer weapons and the money diverges for different wallets, only one wallet in the right pocket and the other in the left.

    This is normal - one works under a license for the civilian market, the second with military orders.
    Returning to the issue of upgrading the M16 for the 4 month, it should be noted separately that the final result can boast of an automation system different from the M16.


    This can be called a deep modernization of the M16, using a modular design.
    The main plus of the modular system is that in mass production weapons are much cheaper.

    + Of course. The unification of units has always been the fad of American war industry, starting with the first Colt revolvers.

    In general, Remington ACR (Bushmaster ACR) is an indicator of how modern weapons should be designed.
    In itself, it does not have obvious advantages over the M4, except for reliability and workmanship.

    I have only one question - why all these bells and whistles? Next - the same receiver and under the machine and under the sniper - citizens, is it a sniper or another machine? Someone here was indignant at the insufficient rigidity of the box on some kind of sniper barrel - but what will happen to this miracle? Universalism has never brought the desired result - any trunk sharpened for a specific task will be much better and more convenient than this miracle. Correctly, someone said here - they’ll shut themselves up, they’ll shut themselves up, and they’ll make Kalash.

      This is a sniper for Marxman. Machine with increased accuracy. The usual thing.

      Any automaton is itself an illustration of such universalism. They once did not want to take them into service because of this. Just for this reason - there were weapons that coped better with specific tasks. Therefore, if you experiment with anything, then with a gun, because his user, depending on the situation, is his own attack aircraft, machine gunner or sniper. Under universal tasks - a universal weapon. Modularity is one way to cram a weapon that is not needed in one unit.

        The result will be negative. Every complication of the design is a decrease in reliability. I can say right away, as a design engineer with 30 years of experience, the barrel does not roll.

          Not necessary. For example, AKM is more complicated than a mosquito. The point is not only in complexity, but also in the level of production.

    How much? What has been added to the AKM compared to the three-ruler? A piece of iron called a bolt frame? So he is in the screw, but not so artsy - this is the whole shutter. Well, Michal Timofeich divided the shutter into two parts and forced to reload not with his hand but with the exhaust - this did not particularly complicate the design. The main principle has remained unchanged - this is locking the bore by turning the shutter. So this did not add complexity. Here in the M-16, yes - there heaped up above the roof - one shutter in the form of a piston with just a huge area of ​​rubbing surfaces is worth what.

      How much?

      Bunta here laid out a series of articles about AKM from the point of view of the designer and engineer. Nuances were revealed, to which ordinary users felt like the moon. There is also a series of historical articles about the first self-charges, which were created by different designers since the 19th century, but they never went into the series, for obvious reasons. Yes, and not a single VO ... For example, I read somehow how difficult it was to create a store for AK. This was a separate task over which the whole team worked. In terms of the complexity of the design, production and materials used, the three-line even did not lie next to the AK.
