Sneak Peak: Law Tactical Gen 3 Folding Stock Adapter has a great photo breakdown of the upcoming Gen 3 Folding Stock Adapter from Law Tactical. There are few notable changes on the Generation 3, notably the height of the hinge has been dropped so it is easier to rack the action without racking your knuckles.


There are a few other changes including a set screw  and the ability to easily separate the receivers like a non-folding AR-15. The Gen 3 also includes a Q/D cut out and nice cerakote finish.


Law Tactical expects pricing to be around $229. Dealers are able to pre-order the new generation now. Law Tactical expects to be shipping the adapters very soon.

    More evidence that I’ve fallen behind: I wasn’t aware that the previous generous generations existed. Allowing for the issues to be fixed in the third generation, did the first two catch on?

    • John

      Not really, $200 price tag and the weapon is rendered useless when folded

      • Mike N.

        Agreed. It would be useful for bolt rifle chassis systems that use AR-15 stocks (like the XLR). But otherwise, if you can’t shoot with the stock folded what’s the point?

        • Pete Sheppard

          For the compactness for storage. I like the idea. Snapping the stock open should be very quick, especially with practice. Then again, if there’s any chance of actually needing it, a folding stock will already be open. Just my take.

        • TomcatTCH

          You’d shoot a bolt action rifle with the stock folded?
          Will the ninja terrorist assassins allow you enough time to work the bolt for a follow up shot?

          • dan citizen

            It’s more of a murphy’s law thing.

            I have seen a person in combat and while under significant fire raise their weapon and attempt to fire, then lower it raise it and again, attempt to fire. After 4 or 5 such attempts they noticed the selector was on “safe” all while taking near misses. This was a extremely well trained person with extensive combat experience.

            In real life people panic and they fumble, forget, an do illogical things. If this weapon can be discharged with the stock folded, it will be discharged with the stock folded. Whether or not it is a good idea.

          • ClintTorres

            Totally agree…last time I went to the range I forgot to lock back the action on my 10/22 during the target break and the RO pointed it out and I fumbled with it for like 10 secs like I never saw a rifle before.

          • dan citizen

            “like I never saw a rifle before”

            I have done exactly this.

          • Commonsense23

            What do you consider a extremely trained person? Extensive combat experience?

          • Mike N.

            Of course not. Never implied that it was so you could fire a bolt gun with the stock folded.

            On a self-loader, I’d say most people expect to be able to fire with the stock folded (like basically on every other self-loader, AK, SCAR, Sig 550, etc., that is available with a folding stock), and if you can’t do that on an AR it’s kinda pointless for its original intended application. Like Dan Citizen states, you expect it to happen on a “combat gun”.

            On the other hand, it can be useful in other applications, like bolt guns. Nobody expects to fire a bolt gun with the stock folded, but lots of people like a folding stock for compact carrying, ease of removing the bolt for cleaning, etc. A folding stock on a bolt gun chassis is surprisingly hard to get and/or expensive: on the XLR or other chassis that use an AR buffer tube and stock setup, you have to resort to these kinds of third party measures, or on chassis like an AICS or KRG, it’s 25-33% more expensive for the folding version.

      The AR pistol/SIG brace market has embraced these adapters. On the ARFCOM AR pistol picture thread you see plenty of the previous generation LAW folders.

  • gunslinger

    folding stock ar 15?

    well then

  • Eric

    I have a Sig 556 pistol that came out before they introduced their arm brace. Now I’m thinking about how much more fun it would be if I removed the end cap, added a folding stock adapter (like this one), an AR-15 pistol buffer tube (like the Phase5 Hex-2), and a Sig arm brace. My question is this, does anyone know if that would be functional? And second, would removing the end cap of a Sig 556 pistol show intent to turn it into an SBR in the eyes of the ATF?

    • echelon

      It would be very functional.

      The firearm is classified as a pistol. By you adding a pistol buffer tube and arm brace you are in no way showing intent to create an SBR. And since Sig makes a model of the same pistol with a buffer and brace already installed you definitely don’t have anything to worry about.

      • Eric

        That’s what I was thinking, and that’s logical too. I was only wondering since in the past (before Sig came out with the arm brace) Sig used to tell that customers who inquired about removing the end cap of a Sig 556 pistol for any reason would be showing intent to create an SBR in the eyes of the ATF.

        • echelon

          Would it be cheaper – time and money wise – to just sell the pistol you have as is and then just buy a new 556 pistol with the Sig brace and tube already on it? You could always then just add the folding adapter to it at that point…

    • BillC

      Look at the first picture, that is a SIG Arm Brace, et voila, pistol.

  • Rafael

    Does anybody know if this will be compatible with the Magpul UBR? I have spoken to people who own the Gen 2 adapter and they claim they had to alter the UBR stock slightly to allow the adapter to fold and maintain the tension needed to keep the stock locked in place. I’m curious as to whether this is the norm or will it be addressed in the Gen 3?

  • Dan-O

    You guys are missing the point of this product. It gives the user the ability to modify existing buffer tube platforms and make them into a concealable, rifle cartridge based PDW. For example, a Sig M400 with an 11.5 inch barrel with that stock adapter and the sig arm brace folded, will fit into any backpack longer than 20″. The idea isn’t to shoot it with the stock closed (that’s what folding AKs are for), the purpose is to get an AR compact enough so the concealed carry bag doesn’t appear long enough to contain a rifle and give you an advantage.

    • dan citizen

      but what exactly happens if you do fire it with the stock folded?

      • Ben

        It fires one round, the slide reciprocates backwards very quickly and jams its-self into its rearmost position.

        You then have un-jam it (smack the back of the bolt to unstick it) and push it to it’s forward-most position. You would close the hinge and the weapon should function as normal, assuming nothing has been damaged on the bolt carrier (gas key sheared off etc) or upper.

        In you are in a position where you wouldn’t have enough time to close the hinge before firing, you’d be heavily in the shit anyway.

        • dan citizen

          great answer, thank you. I assumed since the only missing resistance is the weight of the buffer and the force of the spring it would likely not be a catastrophic failure.

          I noticed that everywhere in this thread (and on the interweb) people assume to make a mistake in combat it must be really be going badly. I disagree.

          I imagine that rather than it being a situation of “no time to unfold the stock” it would just be the regular response of normal people in combat.

          I have seen extremely well trained and combat experienced soldiers make crazy mistakes when under fire. Leaving the safety on and repeatedly trying to fire, dropping full magazines, performing a malfunction drill because the other guy didn’t fall down when shot…. I myself have dropped a functioning firearm and went to a backup when an unrelated piece of gear failed.

          • John

            My problem with this adapter renders the weapon useless if fired with the stock folded. It intentionally breaks (crimps part of itself so the stock can no longer be deployed/the weapon cannot work) and makes the weapon completely nonfunctional to prevent catastrophic failure.

          • dan citizen

            causing a part on an AR to break is kind of going for the low hanging fruit…

      • Cymond

        There’s a metal “finger” that raises when the stock is folded, which holds the BCG from falling out the back. If fired, that ‘finger’ will distort. Once damaged, it can no longer retract, so there is no way to operate the bolt, even with the stock extended.

        I read an interview somewhere, and the designers talked about that ‘finger’. It is designed to distort to absorb the energy, rather than causing damage to other components, like the lower receiver or the hinge.

        In short, don’t do it.

        • dan citizen

          Wow, too bad there isn’t a mechanical device that would store and rebound instead of deforming, you know, like a spring?

          • Cymond

            Yeah, but that would add yet more bulk & complexity to a system that is already a dramatic modification to the original system. A spring instead of the finger would still only give you a single-shot before opening the stock and manually chambering a new round. Or did you mean a buffer spring? Because that defeats the whole point.

            The point is to make an AR-15 as compact as possible for storage & transport, while still allowing it to be brought into action quickly (as opposed to separating the upper & lower receivers). From my view, if you foresee any likelihood of needing the firearm, the stock should be unfolded and locked into position.

            An AR-15 pistol with a folding SB-15 is actually small enough to carry in a backpack or messenger bag, yet still deliver rifle-like firepower.

            If you really must have a compact AR-15 that is still capable of firing, try to get ahold of a North Eastern Arms stock. Be warned that they are expensive and require a special carrier.

      • thebronze

        Nothing. You took a single-shot rifle and made it into a no-shot shot rifle. The FSA is designed to retain the bolt carrier (to prevent injury to the user) but if you fire it folded, it will fire that round and that round only. Then the FSA will probably need to be replaced. But it won’t damage the rifle.

        Does no one do research on the internet any more?

  • Carvey

    Standard lower with bufferless AR upper with this adapter…..

    • ClintTorres

      ARAK-21 comes to mind. Bufferless could use something much simpler to achieve the same functionality.

      • noob

        Which is better, to get this with an ARAK-21 and keep all your AR-15 accessories you love, or just get used to rock and lock magazines and buy a SIG540?

        • ClintTorres

          Depends on how much you like customizing.

          Me? The AR platform is the only way to go…so many options it’s ridiculous.

          Most you’re gonna get from Sig5XX is a railed fore end.

    • Michael R. Zupcak

      You can get way cheaper options for those, though. Plus, the ARAK-21 is the only bufferless option for a standard AR lower. Rock River Arms “promised” to release an adapter for their PDS uppers to use on standard lowers, but they never did. Then there is the Para TTR design licensed from YHM/ZM but no one makes those anymore either, so the only option there is to pay a premium for something you won’t be able to easily find parts for. Supposedly Sig Sauer is planning to release the MCX to civilians at some point, that’s a bufferless design that fits on a standard lower (in it’s current prototype form). No ETA on that, though.

      • jcitizen

        Thanks for the reference to the ARAK-21! That upper looks awesome!

  • dan citizen

    So who decided a self ejecting bolt carrier was an upgrade?

    • John

      If it is anything like the previous generations:

      If the gun is fired with the stock open, the bolt will be locked, it won’t injury the user.

      The Bolt Carrier Extension part, when installed correctly, will hold the Bolt Carrier Group in place.
      **The Bolt Carrier Extension will also stop the Bolt Carrier Group from flying out and causing any injury or loss of life if someone should accidentally fire the weapon with the stock folded. If fired when folded, the locking finger will bend, preventing further operation of the weapon until it is replaced. This is done to eliminate the possibility of catastrophic failure of the adapter due to repeated misuse.

    • Greg

      The tooless bolt carrier extension is an upgrade because you can shotgun the rifle for cleaning with the use of tools. The previous model required a wrench to remove the extension before poping the rear takedown pin for cleaning

  • grammar-nazi

    Sneak peek? I knew peaks could be tricky but now sneaky too?

  • Cymond

    A lot of people look at the LAW Tactical folding adapter and complain that it doesn’t fire when folded. Would you rather have a firearm that doesn’t fire when folded, or a firearm that doesn’t fold at all?
    Seriously, put a Law Tactical folding adapter and a Sig arm brace on an AR-15 pistol and you have a rifle-caliber firearm capable of fitting in a typical messenger bag or backpack. That’s a pretty serious package, even if you do have to open the buffer tube.

  • thebronze

    This is a GREAT product (IMO) but they keep increasing their prices. They’re going to price themselves out of the market before too long…

  • jcitizen

    I’ve thought of developing a kit that takes design principals from the AR-18, it would just be a matter of making the mass meet the piston impingement system. The AR-18 uses a telescopic bolt – however, but if you put a solid carrier behind the bolt head, I think one would be able to get full action within the length of the receiver – I really don’t know what would happen if you tried this with gas impingement, as it would be hard to balance the mass with the different recoil spring set. I’m confident no special tools would be necessary with a properly designed kit. Some piston impingement kits are already available on the market, but I’ve not tested them yet.
