Ever since I first bought an AR-15, I’ve wanted a fire selector switch that went “all the way to 11.” There’s something amazingly fun about firing as many small bits of lead as fast as mechanically possible and the grin it puts on people’s faces is astounding. Now, TacCon has come out with a trigger that (according to sources) when placed in the “3rd” mode, uses the force of the buffer slamming home to assist in resetting the trigger. Fast. It’s kind of like a bumpfire stock in that you’re still pulling the trigger for each round, but the gun is helping you out a bit. Each trigger ships with a letter from the ATF proclaiming its legality and, needless to say, we’ve asked to be put on the list for one. Stay tuned.

  1. Interesting, the stock trigger for my AR leaves much to be desired, so I have been shopping around lately.

  2. Well, well, well I may just have to get me an AR-15 with one of these triggers in it, unless they can do one for the scar.

    • +17 ! As long as the single fire trigger is comparable to the better aftermarket triggers out there, I NEED this on my SCAR!!

  3. My only critique is that it does not fire faster.

    But hey, it sure beats the Hell out of a sore trigger finger. 😉

    • That is also my only critique. I have a slidefire stock and it’s very quick, about 800 a minute like the real deal. If the tac con is everything it’s said to be, I will get one for my 2nd AR

  4. Huh, I would have thought that would have crossed a line by having the gun do more than the bump stock (which doesn’t even have a spring, right?)

    Well, it looks fun and more controllable.

  5. So, two identical rifles, one with this trigger, one with (another trigger of your choice)? Blind test?

  6. I talked to the local dealer here in Texas specifically about it. I was skeptical. He told me about the letter from ATF. $495 is what he is asking for the unit. His point was that it doesn’t fire as fast as full auto but hey, who cares? Going to get one after Christmas.

  7. It looks interesting.

    Honestly, it looks like they just have a lighter trigger and stronger spring…

    You can do a lot with a good/better trigger.

  8. So 500 dollars and I get a semi auto that has a 3rd position selector. I must be missing something. An explanation is needed. All I saw was a semi auto being fired fast, and the music was too loud.

    I guess it is good marketing if they sell a bunch.

    • The trigger resets on its own, causing your finger to set off the trigger almost immediately after the weapon finishes cycling. It is therefore a legal full auto mode.

      • Sorry Dany I replied to your comment and meant to respond to someone else’s comment.

        You obviously do not know anything about the mechanics of this trigger and what separates the Tac-Con MR4 verse a full auto 3 stage trigger. I was given a USM4 with the TacCon Trigger and even though it is very pricey after 2000 rds fired through it Saturday I had zero problems with the firing function. I’ve built and operated just about every weapon in the U.S. Army’s inventory as a 11B202C (Infantry for you civilians). The trigger absolutely meets ATF standards & the trigger assembly can in no way be converted into a fully automatic firearm. Do you research and test this trigger out before pretending to be knowledgable about something you don’t understand.

  9. My general opinion is that bump fire, while fun, wastes ammo and is inaccurate as hell… I’m curious about this though.

  12. Sounds like an item I used to have on my paintball gun called a “response trigger” Since most places prohibited automatic markers, w/ the response trigger, you could find a sweet spot in the pressure applied to the trigger where there would be enough force to pull the trigger, but not too much to stop the device from re-setting. The result was a loosely held trigger that mimicked automatic fire quite well, allowing quicker firing, and less finger fatigue. At $500 I’d want to play w/ one of these first. If it really does mimic automatic fire though, it’s really like spending $300, since $200 would be the tax stamp on an automatic weapon anyways.

    • I didn’t see this post until after I posted mine. It uses gas from the blowback operation to cycle an actuator/pneumatic cylinder in the grip frame. The right amount of trigger pressure basically has the trigger pushing your finger back on each shot, and when the trigger resets the actuator releases pressure, so your finger pulls the trigger again. Pretty sweet concept, and I’m surprised it hasn’t been used on firearms yet in some fashion, but perhaps it has been proved ineffective?

      • I’ve _heard_ that the ATF has deemed such response trigger concepts to be machine guns, but have never seen any determination letters to support or refute that statement. Tapping the gas tube on an AR and routing a line to a cylinder behind the trigger would certainly be straightforward (just as was done on Tippmann RT paintball guns by tapping the blowback gas), but I don’t know how well it would actually work in practice.

        • Have Blue? The same “Have Blue” that frequented Doc’s forum years back? Your tech paintball knowledge seems spot-on…
          It really is a small world…

        • WELL Well well… Long time no talk. 😉

          Tippmann did indeed do that with their RT; there was a better concept that was coming out for the Automag, not sure if it ever did since I left the PB world, but it was an inverse of the valve system they had in place… Won’t go into too many details, but I suspect you’ve probably tinkered with it.

          There’s another way of doing the sort of thing that TacCon’s purporting to, but it would require a lot more mechanical magickery, above and beyond what my IT background can easily put to words.

          Have you done anything else industry-changing, lately? I won’t spill the beans for anyone who doesn’t know your infamy… 😉

  13. Seems to me this should be way easier to control and put more rounds on target than an actual full auto gun. This setup gives you a split second to get back on target before the next round goes off. Not many people can be very accurate with a full auto machine, they just fire so fast you dont have a chance to reset. Would like it to be a little cheaper though.

    • Actually there’s a huge discussion about this over at Calguns. It may actually be legal. Multi shot trigger actuaters are illegal, but because all this really is is a S3G in steroids, it may be legal. It isn’t actuating the trigger, it is the trigger.

      • Given that bump stocks are illegal, I don’t think that this makes any difference. And I’ll bet that Kamala cares much about these little details–buy at your own risk. Not being a gambler, especially with my freedom from incarceration and my 2A rights, I’d rather not be the test case.

  18. Is there a reason why you couldn’t do something like the Response Trigger Kit available for the Tippmann line of blowback-operated paintball guns (Model 98, A5, etc.)? It uses excess gas to cycle an actuator that pushes the trigger back into place after each pull. The right amount of pressure on the trigger effectively keeps the trigger cycling continuously.

    I can’t be the first person to think of this…

    • I think the term you were looking for was “Operator as F$&k” (check out the Facebook page, it’s a hoot).

  21. Nice folks at TacCon, HK MR556 platform is already done and the AK version will follow soon. G3 style triggers will be looked at as soon as possible. They didn’t quite expect the massive response from their press release.

  22. I want one just to dump Surefire 60 round mags for fun. But seeing the MSRP is ~$500 I think I’d put it towards another rifle.

    • Don’t see why it wouldn’t the components are not recoil dependent, they are trigger reset dependent.

  24. Before reading comments I actually told my wife…”I hope this is in the $400-$500 range.” Reason is that the trigger I want is $300 so I want THIS trigger system to be equal to a Geissele. Then the extra hundred or two to cover the extra features. If semi-auto is a nice and crisp 2 stage I am sold for sure.

  25. If full auto isn’t controllable, it isn’t useful. This looks more controllable, so I’ll withhold judgement until a more honest test can be performed.

    • That’s what I like about this being a bit slower than true full auto. It spreads the recoil forces out more over a longer period of time assuming you were doing a mag dump. The thing I don’t like about full auto on so many rifles is that it is harder to place rounds on target. If you can’t place rounds on target, what is it good for.

  27. Well you know I would definitely buy one of these, if I had an AR.

    Let me know if they make one for a CETME’s trigger system!

  28. Why someone would want a trigger faster than the Geissele S3G or SS3G is beyond me. With a compensated AR and the S3G it’s very simple to empty a 30 round magazine in about 6 seconds, on target. Less than 5 with practice. When I lend the gun I have to tell friends how to make sure they don’t fire two rounds accidentally. Yet they still fire two on the first intentional shot. Are people so into loading up magazines that they want…MOAR?

    • The nice thing about this trigger from what I have read is that in semi mode it is 4.5 lb single-stage trigger so you can run it like a normal rifle, hand it to a family member and not worry about double feed or being too overwhelming. Then switch to 3rd more and have more fun. It is a mix of both worlds which could be appealing.

  29. Oh, random question. What exactly is this term for this type of trigger? Is it ‘response trigger’? I’ve only seen this listed of paint ball makers, but not for firearms.

  30. IMHO this is like the slide fire stock, a novelty. While fun to play with its nothing more than a waste of ammo. Although I guess the same argument could be made for full auto…

    In CT a slide fire draws to much attention, so this is a no go.

    I’ll stick to my Geissele.

    • The real drawback to a slidefire is it is inaccurate, and forces you to use a hokey stock set up. I like that this is merely a drop in trigger pack that effectively does the same thing as a Slidefire. I wish the price was a little lower (~$300-350), but I guess you have to shell out the big bucks to be operator as F@%K.

  33. What I think will be really telling is wether this helps the fight to repeal the NFA. Since this (and similar devices) is basicly a full auto weapon, I am curious if it will start to show up in crimes. I suspect the will be at leas tone use in the next 5 years, but even so, that would seam to imply that the ban on new machine guns has no real value.

  34. I’m in doubts or confusing… I bought Ruger SR556 and I don’t have rapid fire control, just single pew… I wondering this trigger is right for my rifle?

  35. Can someone please tell me if this will work In a “Windham” polymer receiver ???
    Would love to have one it it will work….

  36. It’s not full auto, it requires a trigger press for every shot, it is mechanically aided trigger reset.

    We used to hate the old fake smg semi autos that had trigger slap back and now we are willing to pay big bucks to have it albeit a gentler and more sophisticated version.

  37. I have 3 bump fires and they are awesome for fun. After some practice, you can get about as accurate as full auto but it’s really hard to learn 3 and 5 round bursts. I’ve shot a lot of full auto too. The magpul 30 round mags never jam in bump fire. I’m considering the TacCon trigger but in the videos, the trigger seems a lot slower the bump fire. Anyone shot both?
