Joerge Sprave’s Revolver Gatling Gun

If mad genius/MacGyver guy Joerg Sprave doesn’t get his own cable TV show, there is no justice in this world. Of course, we’re still waiting for our chance to produce The Truth About Guns TV show. Anyway, meanwhile, would this contraption be considered full auto if the guns were genuine firearms? Time to write the ATF a letter, making sure we don’t tell them we’re setting out to make a machine gun. [h/t WC]

    Gotta love that sinister laugh.

      Technically it is not full auto since the trigger of each gun fires off only one shot per trigger pull. The ATF should clearly define that the term trigger refers to the trigger that is built into the gun itself and not an external device that is designed to press the trigger of multiple guns and simulate full auto. The ATF should also state that an unintentional slam fire and/or chain fire shall not be considered full auto.

      1. avatar TheBear says:

        Yeah that is not how it works. Since the operator is only physically pulling one trigger, that is all that matters in the eyes of the ATF. Please don’t give advice about NFA issues unless you actually know what you’re talking about or you could send some poor, gullible person to jail for a long time.

          In bump fire or slide fire the finger actually pulls and releases the human interface (trigger) every shot. Even using a hand crank requires continuous kinetic input to continue firing. Electric (electronic) trigger devices are specifically addressed by the ATF and cannot induce multiple fires from a single pull.

    2. avatar Sammy says:

      I thought the same thing. He should do a ring tone.

    3. avatar Ragnarredbeard says:

      Yeah, that is a great laugh. Very villany.

  2. avatar Paul G says:

    Being powered by an electric motor would make it problematic if it were real.

    1. avatar Heretical Politik says:

      Just what I thought… hand crank? No problem. Electric drill? Felony.

    2. avatar JasonM says:

      Are you sure about that?
      The motor isn’t technically firing the gun, it’s moving the gun into position to fire.
      It might circumvent the law the way a bump stock does.

      1. avatar paul g says:

        Yes I am sure. Vulcans, miniguns, etc, are operated via an electrionic trigger as well.

    Northern European?
    Of course, outside with snow on the ground in a T-shirt.

    Could be Otto Preminger as Mr. Freeze in the TV Batman
    Ha Ha Ha

    1. avatar Another Robert says:

      Curt Jurgens was Mr Freeze, no?

    2. avatar Rokurota says:

      German, of course. He proudly mentions it on his channel as if it explains his obsession with artillery.

    3. avatar BLAMMO says:

      Yeah, he says he’s “bad-assing” some cap guns but that’s pretty sad. He’s probably not allowed to own anything that’s really bad-ass.

      But I gotta hand it to him. The German workmanship really shines through. That contraption appears to be pretty well-made and functions well.

      1. avatar lolinski says:

        He does have real firearms… a bunch of them. It is just that he likes making slingshots and whatnot. + it is not like you can’t put real revolvers in that frame. Illegal, of course but still possible.

  4. avatar Walter says:

    Definitely, full auto with real guns and the power drill. One shot per trigger pull is all that is allowed. Basically an automatic gatling gun. Using a hand powered drill should be okay.

  5. avatar jwm says:

    This guy is so gonna get swatted.

  6. avatar Oddux says:

    Not the most entertaining thing he’s built (I think that goes to the machete crossbow), but a pretty fun idea.

  7. avatar Gunr says:

    Half the population doesn’t know a real gun from a cap gun. What kind of a response do you think he would have sneaking that “revolvermatic” into a crowded shopping mall and letting fly!

  8. avatar John Doe says:

    Hmm… With real revolvers on that thing, I think it would be considered a machine gun, although the electric motor/hand crank action might give it access to some obscure loopholes. It would pretty much constitute a gatling gun with each barrel having its own revolver cylinder. It’s a nifty idea, but the belt feed is infinitely better for reloading, so this is kinda just for show. I think they actually might make full blown cap gatling guns…

    Can’t wait till he turns his attention to boomerangs! (I hear they’re coming back)

    1. avatar SpecialK says:

      He could have filmed that video at night, but he would have been taking a real shot in the dark…

    2. avatar travis m. says:

      That’s awful, how long did you have to wait to use that pun?

  10. avatar Geoff PR says:

    Does anyone have 4 identical Ruger SuperRedhawks for an…Experiment?

    (Insert Evil Joerge laugh *here*)

  11. avatar Former Water Walker says:

    Yeah outside in the snow with a t-shirt. It’s below zero here in Illinois. I got a good chuckle outa’ this…

  12. avatar v v ind says:

    I say give it to miculek and see what he can do with it from here…..

  13. avatar jbgleason says:

    FWIW. This device would be considered a Machinegun under U.S. NFA statutes. I have direct personal knowledge of a case that was adjudicated in Federal Court in the Northern District of LA and went to the 5th Circuit. It was a Ruger 10/22 with a Zebco fishing reel that turned and actuated the trigger. Would have been legal EXCEPT the defendant then attached a small electric motor and cordless drill battery with an on/off breaker switch to the stock. The courts ruled that the electric breaker switch became the trigger and that turning it ON made the firearm shoot more than one round. “More than one round with a single pull of the trigger” equals machinegun… In this instance, I actually agree with the court’s reasoning as it relates to the firearm technical definition of the trigger (Not to say I think we shouldn’t be able to build a MG.).

    So DON’T do this no matter how stupid you think the NFA laws are and no matter your contempt for the ATF. You will go to jail.

      Thank you for the info. I was not aware that the BATFE regulated cap guns.

  14. avatar IdahoPete says:

    The man defines the term “crazed genius”. Gotta love it ….

  15. avatar beerwhisperer says:

    Mr. Sprave would be a very fun neighbor. Although, I would not want to hear that laugh outside my window at 2am.

  16. avatar Custodian says:

    This man is one suit away from becoming a Bond villain. Awesome.

  17. Cheers, fantastic information males. I know Raj Napal who was a really good attorney at law I am aware, received earned
    1000s of situations performing really hard. Furthermore could be the highest
    rated attorney at law around Europe.
