ELECTRONIC Trigger on .22 LR Vadum Bullpup. The Future? Or Gimmick?

The .22 LR Vadum is a new Bullpup rifle that Miles was able to get his hands on at Bullpup 2016. What makes it unique is the electronic trigger system located in the forward portion of the stock. The electronic mechanism is routed to the hammer, so when the trigger is pressed, the hammer is tripped and the rifle is fired.

    You sound super dreamy in this video Miles.

    • Herr Wolf

      I like circus carousel music at the end

  • Theoretically, an electronic trigger is going to be better than a mechanical one in the sense that an electric solenoid is going to have none of the mechanical resistance, etc, and can be tuned to be much more smooth to fire than a mechanical one.

  • Dougscamo

    Miles….judging from the barrel inclination….were you engaging in .22 volley fire? Or really tall targets…..?

    • QuadGMoto

      It seems that the camera lens was on extreme wide angle. The upwards inclination was probably an artifact of the camera lens.

      • Dougscamo

    Without a mechanical backup, it’s hard to see this as anything more than a toy. Still, these electronic units definitely have a lot of potential as competition triggers; for hunting or defense though, they have a long ways to go before there will be any serious buy-in from the majority of gun buyers.

    • PersonCommenting

      I disagree with this sentiment. Electrical stuff works fine every single day. Many people trust their lives with electric things. While this one is in its early stages we have to start somewhere to get to a reliable platform. I just dont get this sentiment that the gun community will never accept innovation yet everyone is always complaining about there not being anything. They are right because no one wants to really try anything new.

      • ostiariusalpha

        I didn’t say anything about not starting somewhere, in fact I specifically mentioned competition as a good place to root development of this kind of technology in. As an alternative to exclusively mechanical or electronic triggers, the DigiTrigger covered in a previous article on this very blog is entirely innovative: using the advantages offered by the electronic FCG, but with a mechanical backup if and when that might be necessary. Electronic triggers are the future, but not everyone is a fudd just because they don’t get hyped for a .22 LR bullpup gizmo.

        • Anonymous

          The DigiTrigger is great for standard-layout firearms that already have good trigger designs. This is specifically for bullpups, where the mechanical trigger sucks. This concept could be added to bullpups, and the crappy mechanical trigger could be left in place as a backup.

          The DigiTrigger does have software-programmable components, which may be a problem, since you can’t tell what software is written to them by simple inspection. The software alone could make the trigger behave in an illegal manner, by storing up shot impulses and later releasing a burst, or by releasing more than one shot per trigger function.

          I like the Digitrigger too.

          • ostiariusalpha

            You’ve got it exactly. Keep the crappy mechanical linkage trigger as a back-up, with the nice electronic trigger for standard shooting, at least on serious use guns; range toys like this gun can do without. Programmable units like the DigiTrigger really could use some added security, perhaps being keyed exclusively to the owners smartphone (preferably through a hardline connection; being programmable through a wireless connection is just asking for trouble).

        • PersonCommenting

          Well glad to see someone giving it a chance at least.

    • GE

      We’re not trying to sell a tactical rifle. The real benefit of the electronic trigger in a bullpup is the elimination of the terrible mechanical trigger that exits. Our electronic trigger can also be adjusted for a weight of grams to multiple pounds of pull and from a very short pull to a very long pull. It only takes a minute to make these changes with a flat screwdriver–just turn the screws in or out or re-position them.

  • Audie Bakerson

    Not until we have NFA repeal. Electronic trigger’s most obvious advantages are with full auto.

    • allannon

      And it seems like a foot in the door for “common sense smartgun requirements”.

  • QuadGMoto

    “Electronical”?

    • Jake

      Mechanolectrical.

    • John

      Yea, he was being ironical.

    • GE

      I think he invented a new word.

  • Jeremy David Thomson

    How do the electronical components differ to electronic components?

    I guess the next step would be to replace hammer, firing pin (& spring?) with a solenoid setup. Less mechanical stuff moving before primer ignition being a good thing?

    • int19h

      You could get rid of the moving stuff completely if you replaced the whole arrangement with a laser. Although it would probably require different primers?

      Actually, would it be possible to create primers that would be triggered directly by a sufficiently strong current? I mean, there are many explosives that do that…

      • Jeremy David Thomson

        I suppose there’s a sequence of electrifying the gun that starts with the trigger, then ignition, then the action and ultimately using electrics to propel the bullet. Once you start messing with the cartridge ignition, why not change everything? I guess evolutionary baby steps are the easiest path to change.
        A .50BMG necked down to drive a .177 doesn’t work too well. With electrics you might extract the energy from the equivalent of a .50 cartridges powder to drive a two large diameter pistons in opposite directions. The pistons are connected to magnets that travel within coils to generate current. That current drives the coil gun to move a bullet FAST. Big pistons moving a small distance proving energy for a small bullet to move a long distance in equal time. Yes its complicated, but it might just hold together a lot better than the necked down .50″

        • int19h

          The problem with this is that so far, we don’t know of a way to make a railgun that is compact enough to use in a man-portable weapon, yet can accelerate bullets to the velocities compared to what we can get with powder today. The best that we have is that giant Navy railgun that basically requires a ship to mount on. This may well be a solvable problem long term, but it’s still far off.

          But if you keep the powder, so far as I can see, everything else could be electrified today. There are doubtless problems to solve along the way, but it’s all mundane engineering stuff, not a big problem like railgun design.

          One other interesting possibility is an electric locking system. If the bolt could be moved that way, you could have easily controllable variable fire rate, and could get rid of gas piston/tube completely. For that matter, you could control locking electrically as well, and then all kinds of crazy things are possible – like feeding rounds from the mag by magnetizing the chamber, and using a falling block to lock, ditching the bolt entirely 🙂

      • QuadGMoto

        Remington actually did develop such a system several years. It used different primers, which can still be purchase even though the system was a commercial failure.

      • noob

        I think tfb is running a link for an article on the Voere x3 laser primer ignition system on this very blog. so the special primers exist.

  • Tyler McCommon

    The owner comes to my range to shoot….

    • Jack

      And then…

      • iksnilol

        I dare assume he shoots then.

  • kyphe

    The problem with electronic triggers is there is currently no easy way of telling with a basic inspection whether the device has been hacked to have full auto or burst fire capability. Such capability can be controlled by a bluetooth signal from a phone and would require the unit to be sent to a lab to test if it legal then you have to prove the owner knew there was an illegal modification which on a firearm that may have changed hands a few times would be very difficult to do.

    • Herr Wolf

      “currently”- pun intended or no?

      • kyphe

        lol I will claim it as my mind tends to do that. I posted on a site about the rogue one trailers saying the first trailer was full of bad acting but the second gave me a new hope.

    • Iggy

      Bluetooth signal requires a bluetooth receiver though, if its a straightforward electronic circuit to trigger a solenoid, you have as much chance of ‘remotely hacking’ this as you do a calculator. EMP is a concern, maybe, but that can be shielded against and the only reliable way to generate one is a nuclear blast so you’d have bigger problems to deal with in that instance.

      • kyphe

        The term electronic in relation to triggers is the use of circuit boards and chip sets as can be seen above. The term hacking when referring to such chip sets is often the expedient replacement of either a chip or the whole board for one with the desired properties rather than the Movie trope of attaching crocodile clips that plug into your laptop. This chipping/hacking is done daily to get around security and digital rights management on items like cell phones, consoles and tablets but can look identical to legitimate items to the casual observer. A Bluetooth receiver is also simply a chip and the tiny antenna which is often printed onto the board can be hidden easily or replaced by a hidden RDF type antenna that can be anywhere on the device even inside the plastic of the housing the circuit board sits on. I was once a customer of a company called ON Digital which was a national provider of internet access and streaming TV via a set top box in the UK. The company business model was killed by pirates who were easily able to make fake copies of their chip based cards and give people full access to all premium content including pay per view for a nominal annual fee. The company failed to take into account just how readily chip based technology can be replicated in nations like china for very low cost. Knock of electronics factories are always quick to exploit any potential market if they see an opening or a vulnerability.

        • Anonymous

          Yeah, there is nothing to prevent replacement or alteration of the circuit board…. Just like there is nothing to prevent someone from altering any gun. Are we worried about:
          1) A nefarious party replacing parts in your guns to make them misbehave? – Solution – don’t let other people access your guns. Regular guns can be tampered with too, nonunique to elecronic guns.
          2) People modifying their own guns by “hacking” them? Again, people modify/improve/ruin their own guns all the time with dremel tools, sandpaper, etc.

          This gun is solid machined aluminum, it has compartments but non are hidden. All components on the board are visible to inspection. If you are worried that the board has been replaced with a counterfeit, just replace with an OEM board.

          What are we worried about, again?

          • kyphe

            It is the Government who are worried. The problem as stated in my first post is that people can make illegal modifications that are very hard to direct to the average LEO and also hard to prosecute if the fire arm has passed through several hands as you then have to prove the current owner both made the illegal mod or knew about it. This was quite well discussed back when the Superposed ammo electronic smart guns were all the hype. Same concept as metal storm. I mean think about existing import legislation where guns need to be modified so that they can not be readily made into or returned to select fire capable platforms. If someone tries to import a chip based trigger gun then they will have a very difficult time proving that their system can not be modified by the end user. If digital triggers gain popular acceptance you can expect a whole bureaucratic song and dance to happen and ofc a total ban in CA lol

          • GE

            All these modifications being mentioned are in principle no different than modifying a Ruger 10/22 by making mechanical modifications to the trigger / sear/ etc and turning it into full-auto. Legally, you’ve broken the law unless you get an NFA license.

      • tts

        Moderate quibble:

        HERF guns can be made from scrap microwave ovens and are effective at generating moderate (approx. 200yd) range EMP bursts in a portable (30-50lbs depending on batteries you use + duty cycle) package.

        There are also lots of other ways to generate EMP (Marx generators, EM Pinch Devices, and Flux Compression Generators all of which have many different means of implementation) without nukes but that is probably the easiest and cheapest.

    • GE

      You cant hack this rifle & trigger. There is not a processor to hack. Think of it as a digital switch – its on or off–just like a light switch. You can adjust the pressure required to “flip” the switch and you can adjust the distance switch needs to travel before its on. The adjustments are mechanical.

      We have discussed adding a microprocessor, but its not something we’re actually doing right now. We’re thinking a full-auto model with a micro that controls the auto rate of fire would be nice.

  • Joseph Goins

    Miles sounds perpetually stoned.

    • Jim N Jenna SK

      I was going to say that myself. I would know 🙂

      • Herr Wolf

        ha.

  • Isaac Newton

    Future or Gimmick? Could be both, but I like the idea.

    • GE

      Its a sweet rifle to shoot. People just start giggling. Seriously.

      • Isaac Newton

        I bet, with electric trigger tech I think it opens up the question for new (maybe strange) firearm layout. Its a good step if you are building a War Machine suit https://uploads.disquscdn.com/images/27aca6424b278c516963e9c515ce927f528803484e9ed72121f365e8ea477447.jpg

        • GE

          Moving the trigger to another location is something we’ve though a little about. An AR with a mechanical trigger augmented with a micro-switch for an etrigger– you’d lose the ability to adjust the sensitivity of the eTrigger but you’d keep the original mechanical trigger.
          We’ve had initial discussions with another org about moving the electronic switch to a fore-grip like accessory. More discussions need to occur because their “fore-grip” is very unique.

        • GE

          Aiming is the issue with things like that.

  • allannon

    Neither and both, I think.

    I think the primary advantage would be for bullpups, which are a pretty niche market. And maybe military uses–recoilless rifles and grenade launchers, or whatever–which don’t necessarily matter to the civvie market.

    • Marcus D.

      My thought exactly. Bullpups are infamous for their lousy triggers, a function of the long mechanical linkage required. These are a perfect solution to this ills.

  • iowaclass

    This is how guns have been fired on combat aircraft for decades. Migrating it to small arms isn’t such a leap.

    • Independent George

      Forget airplanes; think about how many electronic operations your car performs every second you are on the road; activating a trigger seems like small potatoes by comparison.

  • Broz

    The idea of an electronic trigger is not new…Remington introduced one on their Rem 700 a number of years ago….that one however required special ammo with an electronic primer…this is a good beginning – however as with anything that requires and outside source of power to operate, it’s susceptible to failure at the worst possible time…my main concern would be with an ‘EMP’ attack or thew like rendering the trigger useless without a mechanical backup…kind of like taking iron sights off a firearm

    • 22winmag

      EMP?

      You can live without your vibrator, just like you can live without this silly toy.

    • iksnilol

      Meh, doubt an EMP would fry such simple electronics. Temporarily disable at worst.

      + you have to remember EMP weapons are super rare.

    • Isaac Newton

      An EMP attack and an optic going bad aren’t equally likely

  • Sgt. Stedenko

    If I want airsoft reliability, I’ll give these guys a call.

    • Dan

      Are you questioning the idea or the company in terms of reliability?

  • 22winmag

    All well and good until someone figures out how to hack it and fire it remotely.

    Don’t laugh, the remotely crashed car and remotely crashed airplane are a reality already.

    • GE

      Once again, read my earlier post. this cant be hacked — NO MICROPROCESSOR to hack into

  • jerry young

    This is just another step towards the liberal smart gun, I think we take things to extremes which some times is a good thing but adding electronic fire controls to rifles and handguns is not needed, I prefer the feel of the trigger it gives me a sense of control and I know when I fire a shot and it hits home it was my skill not electronically aided, this would be fine and I’ll even say maybe needed for someone who is handicapped and if you are firing rockets or wing mounted machineguns but I’ll take my mechanical fire control group. and the only batteries I want to have to worry about changing would be in my red dot scope, I even prefer iron sights over electronic scopes but with age comes loss of eyesight so sometimes electronics is needed to keep enjoying doing the things you like.

  • drglide

    No such word as “electronical.”

  • GUNxSPECTRE

    When we get to handheld railguns, it’d make sense to have a electronic trigger considering everything else would be electric.

    It’s like that EM Drive. It’s one of few components needed to achieve FTL space-travel, but it’s a REALLY good start.

  • Great_Baldung

    “The future? Or gimmick”?

    Uh, why not both? Maybe it could be the future of gimmicks. Or just a future gimmick.

    Well, of course, but it isn’t really “hacking” something if you have full access to it – that is like hotwiring your own car. The electronics in the gun are neither programmable nor externally accessible (no radios, no programming ports, no programmable components). The gun as manufactured has the same “hacking” risk as any purely-mechanical gun. Sure, you can modify it, but someone isn’t going to remotely flash it from across the room.

  • Anonymous

    Pardini, Moroni, MatchGuns, Walther, and others over the years. Those companies all make rapid fire semiautomatic pistols, many make single shots as well. They are expensive but cool.

  • GE

    Go for it. Hack it. I dare you.

  • Joe Gamer

    This would fix my 10/22 bullpup trigger problem! Doesn’t look quite as cool as the

    Center Balanced Systems ones though.
