Evolution Weapon Systems: Shoot Your AR With Law Tactical Folded

The Law Tactical folding adapter has made a name for itself for those looking to have a folding stock or brace on their AR builds. The latest iteration of the Law Tactical folder allows the user to fire a single round. But since the buffer and spring are retained in the buffer tube, you cannot continue to fire your AR.

Well Evolution Weapon Systems has come up with a new system that is shrouded in mystery at the moment. @TheGatMan teases us with a video demonstrating the new system on an AR pistol with the buffer tube folded using a Law Tactical folder.

It's almost done!! @evolution_weapon_systems

Here is another video showing off the bufferless BCG. We do not get to see the magic and sorcery behind this but hopefully we will soon.


In the meantime stay tuned to Evolution Weapon Systems for more info.

  • Anonymoose

    I thought it might be doable with a .22 conversion bolt and a rubber stopper. This is something else, though.

    • Hoplopfheil

      Sig MCX type thing, maybe?

      Whatever it is, I want one.

      • Jared Vynn

        The SIG mcx is a short stroke piston which is how it gets away without a buffer. A 22lr is a straight blowback, but because of the small size of the cartridge it is possible to fit the bolt and recoil system into the space of a normal BCG without needing the buffer.

        This appears to still be a direct impingement system though as the is no readily apparent piston system.

        • randomswede

          I believe the LR-300 is both bufferless and “direct impingement”, I don’t know if that is achieved by way of a “special” spring or if the gas system is different from Mil.Spec.

          • roguetechie

            Yes lr300 and the follow on para ttr do this trick quite nicely.

            There’s also the Daewoo k1a1 guns, which are bufferless and DI.

          • miniguyvegas

            So too is the old Oly Arms guns. I’d guess the BCG is basically a bolt, and a big spring behind it. No real reason the buffer tube needs to be as big as it is, modern metallurgy and spring design can make it much more compact. Although, I wonder how much the recoil impulse would increase due to the shortened duration of the deceleration.

          • randomswede

            Ian over on Forgotten Weapons just released a video on the OA-98.

            I think the buffer filled a bigger role on the AR-10, but as they had no intention (or need) to do away with the buffer tube the buffer could stay “softening” the recoil.

          • roguetechie

            To be fair there’s actually multiple separate solutions being talked about all at once here.

          • Jared Vynn

            It moves the return spring to the gas key which was extended according to the wiki article.

          • randomswede

            Indeed; “Para TTR BCG” search on google images for pictures of it.
            But there’s no weighted buffer in that system to my knowledge.

          • jcitizen

            I imagine it borrows a lot of space that was occupied by the charging handle too!

          • Stan Darsh

            You beat me to it. It really invokes the LR300/Para TTR rifles’ action. I get the sense that the buffer tube is just for show and doesn’t actually impart any impact from the BCG when closed.

        • Vitor Roma

          Not really. The mcx bcg is a very different design, specially with the placement of the two recoil springs, being piston or di doesn’t matter much in that aspect. PWS and hk416uses a piston, but both require the buffer tube since the bcg still has the typical long tail. I bet they did something along the lines of the Korean k1.

        • Hoplopfheil

          I’m thinking more about the recoil spring arrangement. The MCX has a shortened bolt carrier and a pair of springs directly behind the bolt, right?

          As opposed to the OA-93 which moved the recoil spring bits up above the receiver.

          • miniguyvegas

            The MCX ‘s is on the op rod basically where the gas tube is on an AR.

  • D

    Ultra short BCG with internal spring is my guess

    • Sianmink

      It’s got those two screw heads at the back of the cap, I’m guessing those anchor rods which have internal recoil springs.
      They’d have to have totally redesigned the buffer for this. I’m not sure how much I’d like it with rifle ammo, but a conversion like this for a .45 or 9mm AR15 pistol would be sweet as hell.

      • Jared Vynn

        This could be great for restricted states, with a hammerhead grip and a high cheek piece you could have a featureless rifle without that awkward buffer tube just sitting there.

        • Cymond

          I found the Hammerhead extremely uncomfortable. I would have bought a Thordsen Custom stock if I had stayed in CA.

          • Jared Vynn

            I bought a hammerhead for a project I eventually need to finish. Was using it to build a dragunov style ar15 stock. Need to finish designing the stock plate.

      • Flounder

        The pistol calibers would require a gas system, or at least to not be direct blowback like they ALL are. (i can’t think of any that use a gas system except the mpx… but that isn’t actually an AR-15 pattern, everything is just a little different)

  • iksnilol

    What I’ve always found funny, is that it is easier to fire one handed with the stock open than folded.

    I still like folders, hella easy to carry.

    • Jared Vynn

      I like top folders that double as carry handles. Got one on my Mossberg 500 I use for home defense.

    • DW

      You are thinking pistol stabilizing brace comrade.

      • iksnilol

        No, just easier with some weight back.

    • USMC03Vet

      The Bop It of rifles. Rack it, rock it, fold it!

      • Jared Vynn

        Load it, check it, quick – rewrite it

    • Ryfyle

      If you can find one that at a reasonable price, sure.

    • Bradley

      Sure I would if it didn’t involve paying twice as much for something heavier and less versatile.

  • James

    What? No keymod howling? Am I in the right place?

    • James Earl Jones

      Keymod obsolescence renders whole thing done befo. -7.39 impressed score.

    • randomswede

      It’s a prototype; you always just throw whatever leftover bits you have at the bottom of the bin on those. ; )

      • USMC03Vet

        Using KEYMOD is the ultimate in decoy theft technology because nothing of real value would include KEYMOD. 🤣

    • James Earl Jones

      I’m thinking they used keymod to demonstrate that it can be retrofitted to even the oldest of ar-15 technologies.

  • micmac80

    Virtualy all non Ar based firearms dont need buffer tube and any no DI ar 15 coud be designed that way as well.

    • Kelly Jackson

      True, but this is a buffer / stock kit for existing ARs so I’m guessing it’s not changing anything with the upper half.

      • jcitizen

        It is only for ARs with no buffers, the upper doesn’t need one.

    • SGT Fish

      that’s not true at all. and its more of a recoil spring tube than a buffer tube.
      Mossberg 930, RPD, Benelli shotguns, etc

      • jcitizen

        I suspect the extra metal used for the spring guide rod, make up for the weight of the missing metal on the bolt carrier. Much the same as an AR-18/180 needs no buffer, except the return spring is not behind the bolt.

  • Raptor Fred
  • Shankbone

    Folding semiauto? Thumbs up!

  • Michael

    My guess would be a shortened BCG with a big spring surrounding the latter half of it.

    • joshv06

      You still need clearance for the hammer.

      • Jared Vynn

        Unless they made it striker fire.

        • roguetechie

          M231 ftw!

    • GITS?

  • We’re so far down the rabbit hole of AR dominance that people are openly marveling about how a rifle could possibly work without a receiver extension.


    • Jared Vynn

      It’s blackmagic witchcraft!!! A rifle couldn’t possibly be semiautomatic with out a receiver extension. Next thing you know we’ll have rifles using Glock magazines chambered in 10mm.

      • Tom Currie

        or .45GAP

        • Jared Vynn

          I think anything in .45 GAP that’s not a Glock is a miraculous heresy.

    • Nicholas C

      It may not be new per se, but if it isn’t anything special, how come we haven’t seen something like this for an AR15 until now?

      • SGT Fish

        we have seen things like it. and its obviously a forward spring, piston gun.

      • John Zie

        Deadfoot arms folding stock

      • CommonSense23

        What exact need has there been for something like this?

  • th

    Does anyone know the evolution weapons system website? Not instagram, twitter, Facebook or anything you have to login or create an account on… just a plain website … I tried to google the name and got lots of hits for all kinds of things but not their actual website. Thanks

  • Gun Fu Guru

    All they need is a castle nut with 1913 rail on the end to make this perfect.

    • noob

      or maybe a bullpup stock kit

  • Iblis

    Probably a duel rod/spring system so that the hammer could hit the firing pin. If it fires without the buffer tube, why put the folder on it? Just let me know so I can throw my money at them to get one.

  • junyo

    Is this more than an inch or so smaller than the Deadfoot Arms MCS? So… doesn’t this already exist? And considering the price of the Law folder and the price of EWS’s rifles, I’m not seeing this being a cheaper solution. So why is this exciting?

  • supergun

    Why would you want that tube on that gun in the first place. Just put a folding stock on it with a 16 in barrel and you got a winner. Or pay the royal king tax and keep the short barrel.

  • Chris H

    Short bolt carrier that ends just before the firing pin. Then a simple mod to the carrier key and gas port to wedge a 3/8″ diameter recoil spring and guide rod under the charging handle. I’ve actually had that design spinning around my head for a while. Kinda annoyed someone else figured it out before I had a chance to build it… :-/
    What I do find suspicious is they aren’t using the charging handle. Each video starts with the BCG locked open… so where’s the rub, boys?

  • CJS3

    Shortened BCG with dual springs and guide rods, and a modified hammer to fit between the guide rods. The rear of the upper would also have to be modified to screw in a back brace to hold it all together. My guess is that they haven’t released any details because the back brace/stop (whatever you want to call it) keeps coming loose. Notice the holes on the back of the pistol. The two times he fired it, they moved.
