Mark Serbu and Royal Nonesuch Join Forces to Create the Fire Extinguisher Shotgun

Improvised and camouflaged firearms can be some of the most interesting weapons around, and the best ones combine inventiveness, creativity, craft work, and a sort of apocalyptic chic together into final products that are compelling far beyond the sum of their parts or their actual capabilities and practicality. Mark Serbu – one of the big names in big guns, and Royal Nonesuch – a YouTube vlogger with a penchant for the improvised and dangerous, joined forces together with Serbu’s daughter Valerie (50CalVal), and Mark’s friends Mike and Mike (“Beardo”), to bring to the world the fire extinguisher shotgun. As the video below illustrates, that’s pretty much what it says on the tin:

What possible service could the fire extinguisher shotgun serve? Well, I think that’s the wrong question to ask. Instead, we should consider what it says about the gun culture in the United States that – if you want to – you can go out and build a device like this on your own (following applicable laws, of course). Indeed, the sentiment is truer now than ever before that, if anyone invaded the United States, there would be a rifle behind every blade of grass – and fire extinguisher shotguns, and homemade 3D printed pistols, and anything else enterprising Americans could think of turning into a weapon, too.

    should be integrally suppressed…

    • Wetcoaster

      With a oil filter suppressor no less

    • Tassiebush

      I see what you did there

    • Laserbait

      It would be a game-changa!

  • Don Ward

    I think the most important part of using a fire extinguisher shotgun is to have a good catch-phrase when you use it.
    “Only YOU can prevent forest fires”

  • Y-man

    I think I have my next major project! I have exhausted Fire Extinguishers littering the house up the wazoo, and had only thought of using them as targets!


    • Red McCloud

      The gun in the video is a registered AOW, so I’d put a protruding barrel and tape an AR15 grip or something on it if you were gonna make one in order to make it ‘visibly a firearm’.

      • Mr. C

        Y-man is in Nigeria.

      • DanGoodShot

        Y-man is in a different country. He posts some great articles on TFB once in a while. I think he’s limited to shotguns in his is country so it may be legal. After all it is a shot gun! Feel free to chime in if I’m wrong.

        • Y-man

          CORRECT! Legal – Schmegal here in Nigeria!
          1. Its a shotgun – perfectly legal.
          2. Who will even know? 🙂

          • DanGoodShot

            Hey Y-man,
            1.Looking forward to your next article. Your enthusiasm is what draws me to them. You could make an article about a toaster entertaining.
            2. What a man does is his own business. Isn’t that what freedoms really is about? To do whatever the hell ya want as long as it isn’t putting anyone else at risk. Thats how I feel anyway.
            Hope you and yours have a Merry Christmas!

  • Tassiebush

    Oh I just modify mine to squirt hydrofluoric acid…

  • dP

    Looks like a nice tool for spontaneous toe removal if there ever is a fire you need to extinguish.

    • Dougscamo

      Yup….be careful that you are very explicit when someone yells…:

  • DanGoodShot

    Put some dragonsbreath in that thing. Call it the fire starter.

    • Sunshine_Shooter

      The FireFighter. Not to fight fires, but fight WITH fires!

  • Ambassador Vader

    It would be cool if it actually worked that way you could shoot dragons breath and put out the fires.

  • Frank Grimes

    Shouldn’t he be filling back orders for his vaporware?

  • Those4Years

    Someone put this in Fallout 4, I have so many Fire Extinguisher’s laying around for spare parts I’d build an arsenal.

    Or 2fort, there’s always that.

  • John

    Would be nice if he would come out with his SU-15 people are waiting for.

  • 22winmag

    .410 or is that a misprint?

    You’ve got the super shorty 12ga and yet 12 or 20 gauge isn’t appropriate for a fire extinguisher that could easily be made to weigh between 10 and 20lbs?

  • SD

    Here we go. Another dumb project by Mark Serbu so he can continue to procrastinate the SU-15, for which he already took thousands in pre-orders for almost two years ago.

  • McSquizzy

    Is it just me, or has Mark Serbu’s designs jumped the shark?
