New platform for AR-15

29
The American company WMD Guns of Stuart, headquartered in Florida, presents a new version of the AR-15 platform. The name of this option can be translated as "Chassis". What are the innovations? The main novelty is that the platform is “naked”, without any accessories that experienced shooters could get used to, the website reports gunsa.ru.

Those who managed to see a rifle from an American company say that weapon more like some kind of raw piece, which still needs to be worked on. However, upon closer scrutiny, the specialists change their point of view, realizing that this particular platform option is suitable for professionals who are free to equip the AR-15 with those accessories that they consider necessary.

This approach will allow many shooters to save. After all, usually the company itself promotes a package of accessories, many of which the owner of the weapon will never need. If he himself has the ability to complete the rifle with the necessary additions, then this is exactly what a person needs, who knows a lot about saving and options for the optimal configuration of small arms.

New platform for AR-15


Before the Chassis platform appeared, the American company WMD Guns of Stuart was engaged in the implementation of the Beast platform. The new platform uses special nickel-boron compounds for anti-corrosion coating of parts. The bolt, bolt group, separate parts of the receiver, a buffer tube with a gas block, a loading handle are those parts of the weapon that are covered with a special connection of nickel and boron. By the way, the company declares that everyone will be able to order other parts of the platform with an anti-corrosion coating.

The company conducted work on the use of so-called nitrided bore weapons in this version. This trunk, as shown by numerous studies, has a greater resource, and also allows you to shoot with greater accuracy than the barrel with chrome plating. It is nitrided trunks today are gaining great popularity among professional shooters. Global manufacturers of weapons do not leave such a trend without attention.

Machining used to perform the upper part of the receiver, the lower part is made using classical stamping. Both aluminum alloy is used in the upper and lower parts, the labeling of which in the USA looks like 7075-Т6. In this case, the trigger mechanism of the weapon undergoes special polishing.

The length of the barrel of such a weapon in terms of millimeters is 406,4 mm. The cutting steps are different. If we consider the platform with the basic configuration, then it is “sharpened” under the cartridge of the standard 5.56 NATO / .223 Remington. But there is also the option of using .204 Ruger or .300 AAC cartridges.
WMD Guns of Stuart claims that such an AR-15 platform will be sold at a price of US $ 999. This is already on 600 dollars cheaper than the previous platform. This is how much money is offered to save when buying a basic version of a weapon with the possibility of its subsequent configuration with suitable accessories.

    If I understand correctly, is this platform used a "classic" gas automatics of the AK type, and not the one that was on the M16?

      Nothing has changed, the M16 already has classic gas automation.

        Not very classic because in addition to clones, AR is not used. In this system, the exhaust gases do not press on the gas piston, but directly on the shutter. And this is the capriciousness of this automation.

          The gas exhaust system with the direct action of powder gases on the shutter frame is not at all capricious in itself and in world practice has examples of use except for the AR-15 / M-16 family. For example, in the French assault rifles MAS-1949 and MAS-1949/56, which were widely used by the French army in the wars in Indochina (Vietnam) and Algeria, where they showed such qualities as reliability, good accuracy and ease of use.
          This layout scheme was also used in small-caliber aircraft guns, where it also showed itself well. The main problem of the scheme with the direct effect of powder gases on the shutter frame, the entry of combustion products into the shutter box. In the case of the AR-15 family, which has a very miniature and light shutter frame, which, if dirty, does not have enough energy to complete the recharge cycle, the greediness of rifle and ammunition manufacturers has become the main enemy of reliability

            It is for the gas exhaust system AR-15 is very strongly criticized. Dirt or water got inside the gas exhaust system, the rifle stuck ... and that’s all - the kaput: the rifle is being taken to special workshops for repairs.

            Therefore, they began to produce modifications of the AR-15 with a gas vent design similar to that used in SVD. Only such AR-ki are 2-3 times more expensive than the original. Bushmaster, Colt, Heckler-Koch, Zig-Sauer and many other AR-ki with such a gas vent spank. But, expensive:

      It seems not, in the photo at least the gas pipe is at least perfectly visible. So the automation has remained the same.

        Yes, yes, with all its pros and cons. And indeed this is one of the classic automation systems. Summarized, 3 classic automation systems for the assault can be distinguished. rifles - a direct gas outlet to the bolt group like the M-16, a system with a gas piston, like the AK47 and without a gas outlet, with a half-free shutter, like the German G-3. (not to be confused with barrel locking schemes)

      You are mistaken, my friend! The old M-16 has the same automation, only the gases act directly on the piston-shutter, and not through a bunch of levers like on the AK, and therefore it clogs faster.

        Immediately on the shutter frame, because there is no piston in the EMC initially, although it is optionally installed. AK has no leverage. There is a piston connected to the bolt frame.

          I also wrote about Lego in a post below. But the thought is not mine wink

          In vain people rush to the AR-15. It is not only in service. Most of its many modifications will never go to the army. These are civilian, sports, and self-defense weapons. Only modifications that meet the requirements of the military after passing the relevant contests are accepted for service.

          This rifle was developed at one time as a hunting automatic rifle with low recoil, high accuracy and rate of fire in a semi-automatic mode of firing. It was adopted later, when the patent for the rifle from ArmaLite was bought by Colt and was able to push the rifle through the Senate into the army. Without a serious lobby, the AR-15 would have remained "in civilian life."

    Well, on the one hand, the idea is logical and good - you buy the main unit, and buy the rest and mount the rest as you wish. On the other hand, what can be added to this base module? the forend will still be with picatinny slats, and right now they come out in the factory assembly. Variants of gaskets - well, probably there are different butts on the market in terms of functionality (with or without cheek, adjustable or not, etc.), pistol grip - well, you can also find different variants here. But how significant will the differences be with standard equipment? and is it worth it, that’s the question

      There are a lot of forend options for AR-15. The choice depends on the wishes of the customer and, corny, prices: different lengths and weights; constructions from the usual "pipe" (for hunting) to sophisticated "tactical" ones equipped with Picatinny strips (from one - on top, up to 8 pieces); Forend options with KeyMod mounts instead of or with Picatinny rails - this is a new standard of mountings, more versatile than Picatinny rails and with a lighter design of the forend itself; you can also choose the material of the forend (plastic, aluminum, carbon, wood, titanium); with different mechanisms for attaching the forearm to the rifle.
      Butts, pistol arms, flame arresters, DTK and silencers for the AR-15 are also dozens of species.

      The choice is more than impressive.

      Although the "soup set" itself, presented in the article, is also far from universal. Receivers, damper tubes, dampers themselves (return spring), gates, trigger, barrels, gas pipes and gas outlets, other rifle elements (up to fasteners and screws-springs) are also endless.

      AR-15 is an American Lego constructor for assembling a rifle:

        So the question arises, if any and every detail from the AR-15 can be purchased, then why do we need this basic module? If the end user wants to "assemble" his trunk as it is convenient for him, then it is probably easier to take everything separately.

    Yes, this whole article is crap, or rather, again, the translation of American advertising is absolutely useless for us. In the U.S., dozens of firms, firms, and single handicraftsmen are riveting AR-shaped to order and they can order an ARC in any configuration, and this piece of iron will probably be of interest only to those Americans who are able to only tighten a couple of screws but want to feel like uberhansmites.

    Here's how to look. The price for the "base" bites: $ 999 I don't remember the exact numbers, but the M16 assembled for the army was cheaper, something like $ 800. And then there is also "I need to buy some extras. I looked on YouTube as from Vlad Borisych (our emigrant in the USA), so there he" disassembled "another M4 clone (I don't remember the manufacturer's company and the exact name of the device) with a modified gas automation system (by AK without direct ingress of powder gases into the bolt.) So the cost in the "base" with the barrel unloaded from the forend, forend, butt was something about $ 2000.

      Well no. At the beginning of the article it says: "in order to save money." That is, you buy a nitrided barrel on this "chassis" for the price of a rifle with a nickel-plated barrel and reinstall the parts from the old rifle. And you hang the previous base with parts printed on a 3-D printer and give it to your grandchildren as a training one.

      A little more expensive than covering a nickel-plated barrel with nitrogen

    Designed, probably, for AR fans, who already have the entire body kit in a hundred versions, but there is still no nitrided barrel and nickel-boron anti-corrosion on the mechanisms. For a base for assembling a "constructor" from scratch, the price is too high.
