Hyperdouraku Custom Gun Contest

Hyperdouraku is an Airsoft Gun review blog. They have a custom gun contest and some of the entries are pretty cool. Now before we get into Airsoft is not Firearms, we do talk about airguns on occasion. So set that aside and appreciate some of the cool and ridiculous builds the Japanese have come up with. If you want to check out the entire list of entries, click this link.

Here is one of the winners, a custom Luger. The crenelated front is a standoff piece used for pressing into bad guys for control/compliance. Typically if you try pressing the barrel/slide of a semi auto pistol into something the slide will move back and the pistol might not fire when needed, but with a stand off piece that type of malfunction is removed. I am most concerned about the RMR mounted to the toggle action. Every shot, the RMR will be flipped up and down. Not sure if it will hold zero like that. The creator should have made a frame mount to attach the RMR. Similar to the ALG defense Six Second mount or something along the lines of the mount I have on my STI Steelmaster. The addition of the Grip Force adapter and the front grip are interesting modifications. I am curious how that would feel and point as it looks to have changed the grip angle of the Luger.

I see you like grenade launchers so I added a launcher to your launcher.

The Japanese have a penchant for overly sized bladed guns. You see it in a lot of Anime. This erector set was added to a Glock 18C. If you look carefully you can see a Glock 18C hidden in there.

This is an odd entry. The entrant modified a Nerf Recon blaster shell to fit around a Glock 18C. I suspect this is non-blowback electric pistol since there is not enough room for the slide to reciprocate.

This AR creation actually looks feasible. Some may remember the Warfairy P-15 stock. This is similar in concept. The creator also added the front grip of a P90. I think this could actually work on a real AR15.P90 AR 2 P90 AR 3 P90 AR


Remember the infamous Shovel AK? Well this guy took it a step further and added the shovel.

  • TheNotoriousIUD

    Pretty cool Luger.
    Its been a while since anyone has made anything new that looks really cool.
    I still want a Honey Badger.
    They should have mounted an AR under the grenade launcher.

    • iksnilol

      Reverse OICW?

      • TheNotoriousIUD

        Yeah basically.
        Those things are cool.

  • Azril @ Alex Vostox

    If someone in the state is brave enough to try this customization…

  • Crisara772

    i actually prefer to read an airsoft related article than another “x company releases 3 AR 15 models, with a new A.B.C monolithic handguard and a trigger job and basically no interesting feature whatsoever”

    • Friend of Tibet

      And they called it “We BUILD and DESIGN this xxx rifle(ar15 obviously) from ground up, everything about it feels new and yet familiar, that’s what we proud of…. “

      • Cal S.

        And for that, we’re tacking on another $800 for a total MSRP of $2,500. You should be honored we didn’t charge you more.

      • Grindstone50k

        “And it’s totally used by Spec Ops because one guy who files paperwork for SOCOM bought one for a range toy…”

        • Friend of Tibet

          Proper wording should be “Extensively battle tested by Spec Ops operators….” hahaha

    • Dracon1201

      This x100. Development is stagnant, I’d rather see interesting things like this.

    • KestrelBike

      The nerf recon gun is absurdly awesome and reminds me of that HL2 mod NeoTokyo haha.

  • Nathan Means

    Wait I thought all every AK comes standard with a shovel bayonet… Guess that salesman lied to me.

  • Iggy

    Given the Luger and the Mauser C96 that was posted a while back, I’ve realized that old pistol designs seem to take to ‘tacticooling’ surprisingly well, reality and ergonomics aside.

    • Flounder

      This isn’t tacticooling anything. This is a very well done modern take on a newly manufactured airsoft gun. I WISH He could do this conversion to newly manufactured mausers!

      But no new c-96s…

  • Scott Tuttle

    I think most of us had airguns as kids and eventually went on to gunpowder. I dont mind a few articles if they’re something good.

  • Graham2

    I like the Supper Derringer myself!

    • Graham2

      Super Derringer, not Supper Derringer!

      • Brett

        The latter could be fun. Think of it, a concealable snack delivery system that fire goodies at your mouth at high velocities.

        • Don Ward

          It must be lubricated with… *waits for it*… FireCLEAN!

          • Brett

            I think we should stick to crisco cause now we in FDA territory.

  • Given that a red dot’s utility is independent of sight radius, you might as well mount the RMR to the barrel in Artillery Luger fashion.

  • Shamanjo Shaman

    The RMR mounted on the Luger might be ok since airsoft doesn’t always functions like real firearm… might not “blowback” after each shot. Won’t really know until we see it in action.

    • Cymond

      Nope, this air soft appears to be a realistic gas blowback.

      • Squirreltakular

        That looks hilarious, like something out of Borderlands.

      • Southpaw89

        Not sure a red dot would survive bouncing around like that, at least on a real gun, the airsoft might be gentle enough not to screw it up.

        • Giolli Joker

          Actually I’m surprised that the airsoft action can cope with the added weight.

  • Rob

    In regards to the toggle sight on the luger, it might not be too bad, my father shot competition with a gold cup 1911, that had a red dot scope (non magnified) mounted directed to the frame via weaver rail. Thing shot bullseyes consistently if the shooter was up to snuff.

    • Nicholas Chen

      See that is the key thing. The red dot was attached to the frame. Even slide mounted red dots, like the S&W M&P CORE, have proven to be rugged and solid ways to mount an optic. But attaching it to a toggle? I dont think the toggle has tight tolerances. So you will get some bit of shifting. At least with a slide, the slide doesnt move that much in relation to the barrel. A red dot on a Luger could work, just not how the creator did it here. If he bolted a frame mount to the Luger then the red dot would be solid.

      • DetroitMan

        The Luger’s toggle has extremely tight tolerances. The problem is that it doesn’t offer much of a bearing surface to attach anything. A bigger problem is that the Luger’s cycle is violent. It’s so fast that even modern high speed cameras have difficulty capturing it. So it would likely beat the optic to death in short order. A frame mount or a barrel mount would be more realistic.

        • Flounder

          it is airsoft. A little bit of propane or “green gas” probably just barely pops the toggle up. That RMR will have no issues right there. The only problem I could see is the toggle breaking or warping.

      • Rob

        Sorry sorrry sorry >_< lmao slide slide it was slide mounted
        According to a Piccatiny Arsenal Armorer, a slide mounted sight is possible and preferable since you only have to worry about barrel to slide tolerances, the frame to slide could be sloppy as you want, so long as that barrel locks into the slide precisely the same way each time.

        • Giolli Joker

          Slide mounted RMR are fairly common… although sometimes they take flight, they usually work well.
          On the toggle… nope.

  • Anomanom

    I wish someone out there in manufacturing land would start making new
    manufacture versions of old guns like the P08 Luger and C96 Mauser. I’ve
    always wanted both, but even if I got them, i’d almost be afraid to
    fire them, for fear of breaking something that can’t be replaced.

    • They would be terribly expensive. If you have ever taken apart a C96 you would understand why.
      But a boutique manufacturer could make them for the tiny amount of people that would buy them and at a very high price point, while everyone else complained that they aren’t price competitively with a Glock.

      • J.J

        I think with good 3-d printing they could make guns with more complex designs much cheaper to manufacture.

    • Plumbiphilious

      Both of those guns were designed roughly at a time when making each piece by hand roughly and then hand-fitting it with respect to the rest of the assembly was cheaper than milling precision parts to begin with (particularly in case of the C96).

      It’s why both won’t come back. The C96 is a giant, hand-finished jigsaw puzzle of gun-engineering insanity, and the Luger just requires a relatively finicky (as in, requires a lot of careful fitting) action that needs a fair amount of attention to be assembled reliably in making it (on top of not being able to shoot modern pressure ammo, at least not that I know of).

      In all honesty, one could easily make new guns that looked like them, but internally they wouldn’t be the same at all (as well they would be vaguely harder sells, as they’re actually quite underoptimized ergonomically compared to today’s guns; the C96 has a mighty bore axis and is quite heavy for what it shoots).

      • Nicholas Chen

        I welcome 22LR variants. I have a 22LR luger. It is fun to shoot. toggle bolt works too. I would like a C96 rimfire.

        • Cymond

          What brand is your 22lr Luger? I have a Stoeger that misfeeds about 90% of the time. Strangely, it’s almost perfect with Aguila SSS 60gr ammo.

          • Nicholas Chen

            It is an Ermawerke. Made in Germany.

    • n0truscotsman

      There is a company or two in Europe that did precisely that with Lugers. I cannot think of their names right now, but they were selling for prime prices unsurprisingly.

    • Flounder

      I believe TFB covered a small company somewhere in the US that either was starting to manufacture or already making C-96s but they were 5-6k a piece…

    • Nebelwerfer

      Mauser made some anniversary Luger models in the eighties (using Swiss tooling IIRC), and Krieghoff made a limited run in 2006. The Mausers are quite reasonably priced ($1500-ish), but the Krieghoffs cost $16.000 when new, and I doubt that they’ve gone down in price since then. Unfortunately, the Luger frame is extremely complex to machine, driving the price up to unacceptable levels for the average shooter. It might be possible to make something work using an EOSINT or similar laser sintering 3d printer (a local company uses one to print titanium suppressors), but it’s not really suited for mass production.

      Fortunately, Lugers are readily available here in europe, and there are plenty of spare parts available, so we can shoot ours without worrying about breaking anything (unless it’s an original with all matching numbers; they’re quite rare, as most of them have had their barrels changed).

  • iksnilol

    I like the P90 stock on the AR. Gives it a kinda utilitarian sci-fi appearance.

    • ozzallos .


    • Giolli Joker

      Possibly California legal?

      • iksnilol

        Doubt it, IIRC thumbhole stocks count as a pistol grip or something in California. For other states it might be legal.

      • Squirreltakular

        Nope. Only with a bullet button or, alternately, something to fill in the thumbhole.

  • Brett

    It’s just awesome.

    • El Duderino

      I know someone with a junked C96. Project alert!

      • Coolhand77

        you have to share when you are done!
        Also, 9mm, or 7.62?

    • TJbrena

      The grip stippling looks way to aggressive, like it’d tear my skin just holding it. Other than that, I always thought this tacticool Mauser was pretty neato.

    • John

      So Han and Leia had a daughter who inherited her mother’s good looks and her father’s cocky swagger, and she decided to make a few modifications to her daddy’s blaster while joyriding around the galaxy…

    • Giolli Joker

      I feel a bit dirty about it, but I have to admit I kinda dig it.

      (I love the Mauser 06-08 as well and I think Ian of Forgotten Weapons has recently got one in his hands…)

  • J.J

    I wonder if that p90 stock would make the gun NY compliant?

    • Nicholas Chen

      I don’t think so. When I was in NY, thumbhole stocks were a no go. Hence the nike swoosh style stock that many NY legal ARs are sporting.

  • Greg Johnson

    Actually, I think a QUALITY Airsoft gun should be in everyone’s toolbox. I went to buy another 1k of xm193, and realized I couldn’t afford to shoot as much as I wanted (I’ve since begun reloading). I bought an M4 airsoft and shoot 300 rds a day. It has markedly improved my actual shooting.

    • Nicholas Chen

      Out of curiosity how has it improved your shooting? How do you quantify that?

      • Greg Johnson

        I can tell that my hold is steadier. Less barrel movement. It used to take me 6-8 shots to hit a soda can at 50 yds (standing). Now I have it down to 3-4 shots. That’ll improve even more when I increase from shooting airsoft 2-3 times a week to everyday. I still need to work on patience. I slap the airsoft trigger too much.

        • TheNotoriousIUD

          Thats with no recoil or muzzle flash though so I dont see how it translates.
          But hey whatever works.

          • Mack

            Same way a .22lr helps new shooters. you can actually pick up technique errors a lot quicker when there is no recoil. Was you got you got the basics rock hard, then move on up to what your going to be using. I could see how an airsoft would help just as a .22 trainer would.

          • Nicholas Chen

            Muzzle climb and recoil has no bearing on hitting your target. It affects target/sight picture re-acquisition. Go look at any slow motion video of rifles being fired. the projectile has left way before the gun has even begun to move under recoil.

          • roguetechie

            You know how most of us learned to shoot on .22’s?
            Learning to shoot on something that doesn’t have the flash and recoil allows you to focus on the fundamentals of trigger pull, breath control, consistent grip and cheek weld, and good biomechanical alignments.
            Perfect practice makes perfect, and muscle memory of a skill you want to be able to continue doing to millimetric precision and faster than the other guy whose doing his best to do unto you before you can do unto him….
            All while a cruel twist of evolutionary adaptation is corroding your fine motor control by the heart beat and your physiology is doing everything it can to make it as hard as possible for you to keep doing what you have practiced effectively.
            In that sense using even an air soft spring gun to double tap the soup nazi repeatedly while you watch TV CAN be a huge skill builder.

          • Ben

            If you use a GBB rifle these is a small amount of recoil as the BCG reciprocates, which is comparable to the secondary recoil on a real rifle. A GBBR BCG a similar(ish) weight to a real BCG and the buffer/recoil spring are the same as a standard rifles’, so you get a similar dip effect when the BCG stops moving.

            Obviously, there is no felt recoil from the BB its-self as that is ~3.9 grains moving at 400 fps.

            Additionally, all the controls are identical so the manual of arms is the same, and you can shoot it indoors (until the neighbors/SO get sick of the noise!).

    • Squirreltakular

      Makes sense. Trigger control is trigger control, regardless of what you’re shooting.

  • Lance

    Like the Glock/Samurai sword combo. bet the next COD game will have it LOL.

    • Xtorin O’hern

      its originally from a Videogame/Anime series lol

  • MR

    Wow, a thirteen pound Glock. I’m thinking a separate machete would be more practical and easier to carry.

  • TJbrena

    My dad started me on airsoft and a tube-mag, bolt action .22 to get me familiar with guns, when I was somewhere between 9 and 10. Worked me up to grown-up guns from airsoft.

    I miss that .22. I never knew what model it was, and I wish I did now, even if .22 is impossible to get.

  • Southpaw89

    Wonder if that P-90 AR-15 stock would be a good work around for folks living in the anti pistol grip states.

    • Nicholas Chen

      Sadly no. The Anti Gunners are aware of thumb hole stocks. IIRC NYSAFE act calls out thumbhole stocks.

    • David Sharpe

      I actually really like that, I would 100% get that stock and fore end if it was real.

  • Xtorin O’hern

    anime related things can really be found in every corner of the internet can they not?

  • Mystick

    There’s a glock in there?

  • Sianmink

    You missed the crown jewel of that community. I would actually like to own the real version of this.

    • It wouldnt work.

      • Sianmink

        Wouldn’t it? I’m assuming the shroud is fixed and allows the barrel and upper to recoil independently. That also minimizes stress on the RMR. I’m not saying it would be easy, but it looks feasible.

        • The picatinny rail would slam into the frame and prevent cycling.

          • Sianmink

            I’m figuring that part, along with the entirety of the shroud, could be attached to the frame, leaving the barrel assembly untouched and free to recoil. I mean, it’s doable.

          • It isn’t impossible, but as the creator of that gun has laid it out it wouldn’t properly function. I would forego it though in favor of Han Solo’s rig.

          • Sianmink

            Right, I’m not disputing that.
            I think it can be done with a little care though, and that would be awesome.
            The trick of getting a Han Solo rig is how to keep all the bits from falling off when you shoot it.

  • Wetcoaster

    Interesting, I didn’t notice that it was a Luger until mentioned in the text, figuring it for a blowback .22 of some sort (Ruger, Hi-Standard, Buckmark, what have you)

  • Giolli Joker

    Sexy, and definitely more classy.
    Still like the monstrosity, though.
