5.56 Microgun and Bullpup Shotgun

@Empty_Shell_LLC and @Aeroknox have been posting progress pics of their 5.56 minigun project and their D12 bullpup shotgun project.


Here is a video of a successful test fire. It is a burst of 5.56. Looks like 10-15 rounds. The first clip of the video is real time. It looks like one bang. Then they show slow motion.


According to Aeroknox, these will be available at the end of the year. No mention of price. Obviously we cannot own the microgun, but I would love to try shooting one.

    All kinds of awesome!

    Dodge needs to make the mini an option on the Charger.

    I’m rethinking my whole occupation. I need one, I need one, no I need two!

    • Anomanom

      Two microguns, what are you planning to occupy? Luxembourg?

      • Major Tom

        He’s planning on dual-wielding both microguns.

        • PK

          New life goal, right there.

      • Dracon1201

        Sure, why not?

  • DIR911911 .

    looked more like only three or four rounds in that burst clip

  • Major Tom

    I’ll take two of each please. For the microguns, one will be equipped for portable use, the other will be mounted.

  • Joe

    In the “real time” shot it does look like a single shot. There is no belt of ammo hanging out, and no shells drop to the ground like in the slow motion.

    • Jwedel1231

      Well, that concerns me.

      • KestrelBike

        There also seems to be only 3 or so “flashes”, definitely not as many flashes as the amount of dropped brass seems to portray.

        • Ryan

          You can’t count the number of “captured” flashes to determine the number of rounds fired. There are a lot of factors that would cause those numbers to be different. For example, shutter speed. One or more flashes might happen while the shutter is closed. However, I do think that the normal speed and the slow motion videos are from two different firings and differ in round count.

    • kyphe

      Second slow mo is the same as the real time, these are two different firings.

    • Nate Reinhold

      If you look at the design of the micro closely you can see that the belt doesn’t feed directly to the action, there is a small “drum” section that the belt feeds into and around before entering the chamber. It looks like it may hold about 8 rounds in it so you’d have to have more than 8 shots loaded to even see the belt hanging out of it. Also the dude about the camera shutter speed/frames-per-second that it’s recording in. If the fps is, say 30fps (the human eye refreshes at 52 “fps”, thats why 30fps recordings seem jerky to us) the will be several shots missed during the shutter closed cycle.

      • Paladin

        The human eye has no framerate. Eyes don’t work like cameras.

  • Tassiebush

    This is awesome. I think someone ought to make a hand cranked bipod lmg version of the Gatling.

    • Cattoo

      Someone made a Gatling .22lr hand crank model. Steampunk style.

      • Cymond

        I saw a video of a steampunk 22lr ‘gattling gun’ but it was actually just a 10/22, a cheap crank trigger activator (BMF), and 6 rotating fake barrels.

      • Tassiebush

        Yeah I like the look of scale model .22lr ones. I quite like the notion of it in LMG format though which I don’t think has been done. I recall seeing an ad somewhere for the plans for .22lr Gatling.

  • Anomanom

    Worlds smallest Brrrrrrrt?

    • SF

      actually, there have been people that have made working mini miniguns that fire 22lr. ive seen the pictures and a video. its pretty impressive. And the microgun in 556 isn’t anything new, GE made the first one and its transferable. it was originally intended to be handheld but never made it into full production. Ive been waiting for someone to build some post samples as there are quite a few companies that make M134 copies now, so as long as you have the prints, it shouldn’t be any harder to make a microgun post sample copy

      • PK

        The GE 5.56x45mm project was the XM214, wasn’t it?

        • SF

          correct. there is one transferable in the registry, ive seen it in person. Its a sweet little gun that just never got a contract. I have no idea how many post samples have been made. but it appears that this one has some original parts on it, or they could possibly be m134 parts made to fit the xm214

  • TheNotoriousIUD

    Any holsters available?

    • PK

      Custom basis, of course.

      I think a scabbard might be more fitting…

  • GerladTheMagnificent

    I need that bullpup in my life.

  • Geoffry K

    Seems Instagram video does not play in Firefox.

    • Nicholas C

      Plays in my Firefox

  • hikerguy

    Can’t afford to feed the minigun, but that D12 would be a cool thing to have.

    • Joe

      Any details on the bullpup? Looks like it could be a semi, more power to them.

      • PK

        Other views show a slot for the VFG to travel parallel with the bore, so my guess is a concealed pump mechanism. I expect they’ll be selling those, though. I’d be happy to buy a mag-fed bullpup 12ga like that, it looks slick!

  • iksnilol

    Hmm, 5.56 minigun has been done before. And I remember the R and R guy firing a minigun (in 7.62×51) handheld… obviously in short bursts.

    I think a minigun in 5.7×28 with P90 length barrels would be *way* more practical though. Would be way lighter and recoil much less.

    • Squirreltakular

      Make a camera arm rig like in Aliens.

      • iksnilol

        I don’t know if that would even be necesarry. I mean, 5.7 has like less than a third of the energy of 5.56.

        My math:

        10 rounds of 5.56 per second (like most ARs and whatnot) = 18000 Joules

        30 rounds of 5.7 per second (assuming you slowed it down to sometihng “reasonable”),= 15000-16000 Joules per second

        + Add a decent suppressor to each barrel and it would be even more controllable. Also, don’t forget the extra weight of the minigun. Though maybe you could make it weigh like 15 kg or something, possibly less?

        • Dracon1201

          Single unit minigun suppressor would be cool. I’ll have to add it to my project list.

          • SF

            its been done by degroat

          • PK

            I knew someone else would mention James’ work. He’s a delightful tinkerer!

          • SF

            yeah, I actually emailed him with the idea years back. He told me he already had it drawn up and on the project table. It wasn’t long after that he published pictures of it but said that there was still some improvements to be made. that was around the time he got busy with the navy suppressor contract. I still haven’t seen any video of it in use but I know it has been used a bit and he has made more than one

          • yes@please.com

            can you track down the pics and post?

          • SF

            google degroat tactical armaments. youll be able to find them on his website or with an images search.

        • noob

          hmm. this could be the first time firepower has ever been measured in terms of Watts (Joules per second) instead of weight of fire

          • iksnilol

            Well, I wasn’t really calculating firepower, I was more busy about the recoil. Since the same amount that goes one way, goes the other way, albeit slower.

    • Greg Kelemen

      The only hassle would be the custom made disintegrating link.

      • iksnilol

        Make a mold, then make a bunch outta plastic.

    • valorius

      Exactly, a manportable 5.7mm minigun would actually be PRACTICAL.

      • iksnilol

        And people tell me that my ideas are “stupid” and “illegal”.

        FOOLS, I WILL SHOW THEM ALL… not you though, you’re good.

  • d_grey

    Definitely want!

  • Ryfyle

    In my few and short years many have told me that a handheld mini-gun was impossible. Glad to see that the nay-Sayers were wrong. Granted that rate of fire is crazy.

    • Jonathan Ferguson

      The naysayers were talking about a hand-held *minigun*, as in 7.62×51. Surprisingly, while pointless, it turns out that even that isn’t actually impossible per se – see Richard Ryan on FullMag (YouTube). But neither that nor this baby Micro-Gun are in any way combat effective.

      • tsubaka

        yup but Ryan shoot a short burst, i’m guessing if you actually hold the trigger longer it will be actually very difficult to handle the recoil

        • SF

          I believe he was shooting blanks also.

          • law-abiding-citizen

            No, if you look at the slow motion portion of the video, you can see the rounds impacting the dirt. Definitely not blanks.

          • SF

            good to know. I know almost all other videos of people shooting hand held M134s are shooting blanks. the recoil forces are something like 300lbs

          • Jonathan Ferguson

            You only have to look at the recoil and how far the muzzle swings off target after only 5 or so rounds. The videos I’ve seen are of him shooting at an AR500 plate and another at some gel, so you can clearly see the bullets in flight.

        • Jonathan Ferguson

          Absolutely. But even 5 rounds vaguely on target is impressive!

      • Ryfyle

        Who knows they might put a proper stock and grip on it and chamber it in a beefy pistol caliber. Might get better results.

  • Harry’s Holsters

    Am I the only one who would like a 22LR mini gun build from a battery powered dewalt drill?

  • gunsandrockets

    Looks closer to a burst of 6 rounds?

    Barrels about 10 inches long? That would make the entire system a lot lighter and quicker to spin up I imagine.

    I wonder if it would be possible to redesign a mini-gun so that all the barrels would fire simultaneously, and loading and ejection would only occur between fire events. Hmm…

    • SF

      if you know how a minigun works, then youd understand why all six barrels firing at the same time would be impossible without making a whole new gun. and totally negate the genius of the minigun

      • gunsandrockets

        Sigh. Great job at missing the whole point.

        • fu@bar.com

          no, you are.

          what you are describing is called: a shotgun

  • d_grey

    I wants big time! *drool*

  • Ernie

    Reminds me of the Venom, a portable gattling gun from one of the old Wolfenstein games honestly.

  • valorius

    A 5.7mm minigun would be optimal. No recoil.
