14″ Mossberg Non-NFA Scattergun

Under current ATF rulings, its possible to create a non-NFA firearm that uses shotgun rounds (note, I did not say “shotgun” which refers to a specific legal definition). By never mounting a stock to a receiver and keeping the over-all length over 26″, Shockwave technologies Raptor grips keep a scattergun legal to own. Users who purchase these must keep the grips on, otherwise they become an AOW requiring registration.

Shockwave has the full details of the rulings (with appropriate letters from the ATF) available on their website. You can check the details and Shockwave by clicking the link here. The “Raptor” grip as its called is available for both Mossberg 500 and Remington 870 shotguns.

  • Kovacs Jeno

    woww. it seems, the government bureaucracy in case of SBS and SBR is unofficially OVER. With these and the wrist brace, who will spend the 200 USD and go through the paperwork any more?

    • echelon

      It’s not anywhere near over. The .gov already changed its’ mind regarding the brace and they can do so on this “scattergun” thingy at any time they please.

      And rather than fight the tyranny of the $200 tax most people just want to be “legal” and so they continue to give the bureaucracy legitimacy.

    • JumpIf NotZero

      Your comment seems to not have any concept that this ISN’T nearly as useful as an SBS. And the SIG brace actually makes a poor “stock” and is not a true replacment for an actual SBR.

      This product above is an option for me, instead I’m filing my form1 SBS paperwork this week along with the $200 stamp. Because the “whiteness protection” style guns with the bird’s head grips look cool, they just aren’t as useful as having a stock.

      These NFA-workarounds are fine, but they aren’t apples to apples to the real thing.

      • Skippity

        Does a “whiteness protection” shotgun shoot blasts of sunscreen? ‘Cause that would make trips to the beach so much cooler.

        • JumpIf NotZero

          Fixed. Spell check on mobile

            Should’ve left it; it added a little bit of levity to a thread that’s taking itself WAAAAY too seriously. 🙂

    • Cymond

      You mean somehing like this? http://www.thefirearmblog.com/blog/2014/11/20/new-ruling-sig-brace-shotguns/

      Yeah, they already tried that. It didn’t work out so well.

  • Tom – UK

    Woah…good thing its over 26 inches long because if it wasn’t then the moment I touch one it’s evil soul would possess me and force me to start shooting in a crowded place while screaming about satan. Thank you ATF (and other country’s ruling bodies) with your omniscient guidance we all so much safer and the bad people are prevented from creating these vicious killing machines by taking a simple hacksaw to a regular shotgun for example….

    • jeffrey melton

      Right, Tom and thank Obama while you’re at it. Obama is the greatest firearm salesman ever.

      • itsmefool

        Until the next Dem president comes along, I suppose.

  • jeff k

    corrections for you lol : its not that you can never mount a stock. the shotgun MUST come from the factory as a pistol grip only weapon. it is not classified as a shotgun it is classified as a firearm from the factory. mine has a sticker on the box that says you must me 21 to own and this was never intended to be fired from the shoulder . once again .. it must come from the factory as a pistol grip only shotgun to be legal !!!!

    • sianmink

      I suppose one of these could be built from a new unassembled receiver as well. So long as the SN# has never been connected to a stocked shotgun, it should be good.
      This would be a lovely setup to ghostgun.

      • Confused Carl

        What do you mean by “lovely setup to ghost gun?”

        • sianmink

          buy 80% Mossberg clone receiver. Complete yourself, add barrel and grip. No SN#, No records, No trabajo.

          the big hole in the plan is I haven’t found anyone so far making 80% Mossie receivers.

          • Cal S.

            Buy a CNC machine.

    • Cymond

      I think “never mounting a stock” includes both the original factory configuration as well as any aftermarket modification.

      To put out more simply, if the receiver has EVER had a stock attached, then it is not eligible for this non-NFA modification.

      FWIW, I’ve been interested in this modification for a year or two (Shockwave posted this 3 years ago), so I’ve done some prior reading &research on these. Sianmink is right, a ‘virgin’ receiver can be built as one of these “other” firearms with a 14″ barrel and 26″ overall length.

  • jeff k

    fyi this is what mine says on the box. it came from the factory as a pistol grip ONLY

    • sianmink

      I think the second half no longer applies since the inter-state handgun transfer ban was struck down.
      I’m not completely sure how it applies to pistol grip shotguns, but if it was rendered invalid for pistols, the reasoning would hold.

      • jeff k

        not sure about that but thanks i will look into it. the law is a bit grey as this is not considered a shotgun it is classified simply as a firearm. the only thing the atf could do to make this go away is change the definition of a shotgun, its all in the wording i suppose. but for now as long as my FIREARM (lol) remains over 26″ then im happy with it

        • Cymond

          They could try to *reinterpret* the definition of a shotgun but actually, literally changing the words in the law requires an act of Congress.

          • Bill Funk

            Since the BATFE makes its own rules without the help of Congress, no act of Congress is needed.
            Note the BATFE is, after their fiasco attempting to ban M855 as “armor piercing” when, by their own regs, it isn’t, the BATFE is now working on changing the definition of “armor piercing.”
            Since just about all center-fire rifle ammo will pierce Level 3 body armor, if that definition ends up in the regs, there goes just about all rifle ammo, turning your rifles into clubs.
            Elections have consequences.

          • Cymond

            “Since the BATFE makes its own rules without the help of Congress, no act of Congress is needed.”
            Really? Go read the definition of armor piercing ammunition.

            18 usc 921 (a)(17)(B)
            (B) The term “armor piercing ammunition” means—
            (i) a projectile or projectile core which may be used in a handgun and which is constructed entirely (excluding the presence of traces of other substances) from one or a combination of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium; or
            (ii) a full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile.

            It was Congress that that wrote that definition, NOT the ATF! If the ATF had the power to rewrite those words, then they wouldn’t have to mess with M855, they could just say “The term “armor piercing ammunition” means any ammunition capable of penetrating level IIa armor” and be done with it!

            As another example, it was Congress that passed the 1934 NFA which states: “(8) The term “short-barreled rifle” means a rifle having one or more barrels less than sixteen inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon, as modified, has an overall length of less than twenty-six inches.”

            Again, it was Congress that wrote the definition of a “short-barreled rifle”. All the ATF can do is determine what the words mean. Yes, ATF stretched that definition to somehow include a misused arm brace, but they didn’t create the SBR definition. Further, ATF determines how to measure barrel length, but they don’t have the power to change the 16 inch limit to some other length.

      • HSR47

        Unfortunately, that isn’t how it works.

        There are a number of issues involved, but suffice it to say that until the matter has been thoroughly litigated, you’re not going to find a dealer willing to risk their license/business/property/freedom/etc. to transfer a firearm other than a long gun to someone who does not reside in the state in which they are licensed to do business.

  • Kevin T. RIley

    Your average LEO isn’t going to care, their going to bust you because they’ll think it’s illegal. I’ve seen it happen.

    • Steve

      I have seen a documented case with an AK pistol. It got passed an indictment all the way to a special evidence hearing before being dismissed.

    • Jeff Smith

      Not that they will automatically believe it, but items like this (and the Sig Brace) often come with ATF ruling letters explicitly saying they are not illegal.

    • claymore

      Right sure.

    • Cymond

      If we based our decisions on the perceptions of the “average LEO” then we probably wouldn’t have much left. Once upon a time, the average LEO didn’t know anything about guns beyond revolvers, bolt action rifles, and pump action shotguns. Many police departments didn’t even adopt semi auto pistols until the 80s or even 90s.

  • N.

    Give it time. People will be attaching all manner of silliness to it, and then the ATF will reverse itself.

    • Vitsaus

      People will start shouldering the pistol grip, then writing letters to the ATF asking if they can put this pistol girl on their AR15 buffer tube and shoulder it.

    • floppyscience

      There’s nothing the ATF can reinterpret here. The law is spelled out in plain english. Without an act of congress changing the NFA definitions, these will remain legal.

      • Bill Funk

        No, the BATFE can, and does, alter its official rulings, as the BATFE interprets and defines words in the laws.
        What is “shoulder fired?” WHat is a “hand gun?” Guess who decides. Hint: it isn’t congress.

        • floppyscience

          These shotguns being legal is not because of an ATF ruling or interpretation, it’s because they are specifically a “firearm” as defined by the NFA. There is no loophole, it’s just the class they fall under. They are legally “firearms” just as shoulder-fired 16″ barreled rifles with stocks are legally “rifles”.

          And yes, “handgun” is defined in the law of the text. “Shoulder fired” is also laid out as “designed or redesigned, made or remade, and intended to be fired from the shoulder”.

          The ATF was able to “interpret” a SIG brace as being a stock when used as one because of the ambiguity in the definition for shoulder stock. There is no such ambiguity with “firearms”.

  • Charlie Taylor

    Curious, would putting a VFG on it also turn it into an AOW like putting a VFG on a pistol does. Or since this is classed as a Firearm would it not affect it?

    • If they follow the previous letter, no. Perfectly legal, as this isn’t a pistol, nor is it a rifle/shotgun. It is simply a firearm.

    • AlDeLarge

      It falls under the same category as a Franklin Armory XO-26.

  • Phillip Cooper

    Don’t hold your breath.. the BATFE will likely change the ruling any moment, or right after you’re falsely arrested for having an illegal shotgun, conveniently before you go to trial.

    • JumpIf NotZero

      This product has been on the market already for years. This is the second or third time it’s been on TFB.

      The more apt comment would be asking why it’s being brought up again as it appears the product is identical to the last time it was shown.

      • Hudson

        It happens, you have a media outlet run by several people, some who may have not been involved the last time a item ran, you can’t expect them to keep track of every item they have ever run.

        It not like you are paying for the service.

        Just realize it’s run before and go onto the next item.

        • JumpIf NotZero

          Search their site before posting maybe? I know, how uncouth to ask for a little resemblance of journalism.

        • Cymond

          It’s not like the search feature is at the top of the page. No , wait, it is.

          The on-site searchfeature only finds blog content. You can also do powerful searches if that include comments.

  • iowaclass

    What is the point of a 14 inch barrel, ballistically? It’s not really going to expand your cone of fire appreciably, while it will reduce ballistic energy somewhat.

    • RealitiCzech

      Mostly boils down to “because I can” and “because it looks cool.”

    • JumpIf NotZero

      “cone of fire”, “ballistic energy”

      You aren’t trying to get the shot to leave the cup sooner, no one would want that, despite people thinking you “don’t need to aim shotguns”. If anything you would typically want it later – which is why Federal with FlightControl are such great rounds.

      There is no major difference between an 8″ shotgun and an 18″. The bore is huge and leaky.

      • Bill

        The choke has more to do with shot dispersal than barrel length. Using Federal Flight Control ammo, showed no appreciable difference between 14 inch and 18 inch guns.

    • Cymond

      If you’re looking for a practical reason, the advantage is ergonomic, not ballistic. A shorter barrel is more maneuverable and light.

      • iowaclass

        But with the same overall length — 26″ — does that still apply?

        • Grindstone50k

          Still shorter than a full-length shotgun with a stock.

        • Cymond

          It’s weight & length taken off the muzzle, which is the end that you have to point & swing. It’s also the end that banged a door frame when I tested clearing my narrow hallway last week.

          Take a long stick/pole, grab it by one end, and swing it around. Then grab it closer to the center and try it again.

      • Bill

        Even with a full stock, which is really far more practical for anything except breaching, it’s amazing how “quick” and handy a 14 inch gun is compared to a 16. I suppose it’s like a penis: 2 inches can make a big difference.

    • Bill

      I interpret “Cone of fire” to mean pattern. You don’t actually want a pattern thats very large because you loose the synergistic effect of a mass of pellets striking simultaneously. As patterns get REALLY large you typically wind up with individual .32 cal. lead ball striking non-vital areas at relatively low velocity.

  • RealitiCzech

    I have one of these with a Trijicon RMR mounted. Very fun little hand cannon, and with the RMR you can actually hit things reliably. Buckshot is… forceful. With a tight grip on things, it’s no problem. Slugs and magnum rounds? Might have an issue with that, never cared to try. Standard pressure buckshot is plenty of excitement, and I can still control it safely without the risk of it flying out of my hands or hitting me in the face.
    It should be fired the way you’d fire a Mare’s Leg – held out in front of your face a bit at shoulder height. Firing from the hip doesn’t work so well for comfort. At shoulder height, it recoils back and upwards, so the impulse isn’t so bad. Fired from the hip, it pretty much just recoils backwards, so you feel it more.
    Need to shoot clays sometime with it, just to see if it can be done.

    • sianmink

      I’d use nothing but low-recoil #1 buck in one of these.

  • dan citizen

    This is novel, but….

    Given that I have to keep it 26″, why chop off 4″ of barrel, loose one round of mag capacity, just to add it to the grip end?

    • Cal S.


      And how else are you legally going to dress up for the zombie apocalypse with type-appropriate arms whilst still owning legal weapons? Best thing for apocalypse realists since the PW87!

      This is just an attempt at a non-NFA ‘Super-short’ market intrusion.

      • dan citizen

        I could sure enjoy a Saiga 12 done up this way.

        • itsmefool

          That’s a good point…and being a semi-auto, it would beat up your firing hand a lot less than a pump, I bet.

    • RealitiCzech

      The shockwave grip is much less punishing than the standard pistol grip many of these guns come with – you don’t have the web of your hand battered into submission.
      Plus, it’s got nicer lines.

  • Cal S.

    I wonder what putting this in a modified Bullpups Unlimited stock would do? Would that make this an AOW? Probably. Oy.

  • frank

    Here’s mine I built last year, removed the barrel lug and opted to weld it back on.

  • Drapetomanius

    I love these. Of course they are a compromise when compared to a shoulderable shotgun, but everything is a compromise. As a breaching tool, stash gun, bush pilot gun, etc. I think this is a valid option.

    Naysayers notwithstanding, this should be suitable for social work at conversational distances, and in a pinch I’ll bet I could take game with it to effect self rescue.

    That, and it would look cool as $%^# in a purpose built back scabbard, right next to a machete. Just one man’s dumb opinion.

    CA legal?

    • Cymond

      Are you serious or trolling? If you have to ask about CA, the answer is almost always NO.

      And no, it’s not CA legal. CA defines ‘shotgun’ differently than federal law. You can’t have anything in CA that fires shotshells from a barrel less than 18″. You may notice that the Taurus Judge isn’t available in CA.

      • Ben

        You aren’t completely correct there. In the past you have been able to get the Serbu Super Shorty, as well as the Taurus Judge, as long as you do the transfer as an AOW. I think something about that changed this year though, and I’m not sure how AOWs work here anymore.

        • Cymond

          Yup, you’re right. I keep forgetting that AOWs are (were?) CA legal. I’m out of there now, so I don’t pay as much attention to them.

          It’s a bit ironic that Californians can own an AOW but not this.

    A friend and I both bought Mosseberg Mavericks on sale some years ago for under $200. They shoot 2 1/2″ 12 gauge shells, have legal 18″ barrels. As I have ample hunting shotguns this is a strictly a get the hell out my house gun. My friend immediately replaced his stock with a pistol grip. I kept mine stock with synthetic stock. The gun is not fun to shoot even with stock recoil pad, but with your heart at 150 beats per minute and adrenalin flooding your system who cares. I have shot the pistol grip only gun and did not like it, the recoil was hard on my wrist, hand and forearm, If I didn’t hit my target on the first shot, by the time I got everything back under control, I’d be a gonna. My advise would be to try before you buy, if you don’t have gorilla arms, or definitely need a short shotgun, this may not be the best choice.

  • cbunix23

    Know your state and local laws, those definitions will apply as well. I am not a lawyer, but my best guess is Ohio would classify this as a “sawed-off firearm” which is “dangerous ordnance” unless registered as NFA. PA would require this to be registered as NFA to be legal. TX requires minimum 18″ barrel on shotguns.

  • Mike

    Seems like you could put a Sig brace on one and maintain overall length while also having the use of that

  • Joseph Anthony

    Ok. Where can we get one? Enough “eye candy”…
