AR-15 Trigger To Increase Your Brass Flow

Oh look, another aftermarket AR-15 part:

Price unknown, pre-orders starting Dec 1st over at TacCon.

Cool video.  Terrible website. Terrible explanation of function.

So the lower with the “AUTO” position on it is actually just a semi auto I guess (I don’t see the third pin hole)?  I thought getting a fake “AUTO” lower was only cool in 2011.. people are still doing that?  With this trigger group dropped in, it apparently gives the AUTO position a “positive reset characteristic”. I’m not sure what that means in the context…  it forces the trigger to reset maybe, rather than you having to move your finger forward?  Who knows.  All I know is I like the speed that brass is flying out, and I like how those guys are operating.

Oh and remember guys, it’s not a trigger group… it’s a trigger “system”. hahah I love operator lingo.

TacCon-3MR-Trigger-Operator-SystemThe ATF is so chill lately with all this potentially cool stuff.  Whoever the dickhead over there banning shoestrings was, he must have retired.

  1. Nice tight shot on the crotch at 1:20…the real trigger system.

    1. Gizmo <— F@cken homo.

  2. Hey, are you gonna pick up that brass?

  3. Just another trigger bounce POS for those who need to go full retard…….

  4. A trigger made for bump firing? Think it’ll go off if you drop it down the stairs?

  5. My only guess as to what “positive reset” indicates is that when the selector is switched to the third position the trigger will actively move forward against the pressure of your finger to reset (rather than requiring the finger to move), that way your finger would be activating the trigger for each shot if rearward pressure is maintained. Not really bump firing since the trigger is being mechanically reset and pushing the finger forward rather than using recoil forces moving the entire firearm backward so that the finger moves allowing the trigger to reset.

  6. Still don’t know what we got here.

  7. I kinda want one, it fires faster (for fun at the range) and makes the third selector position useful.

  8. I guess it would be somewhat similar to a paintball response trigger? Except instead of using extra gasses to force the trigger to reset, it uses mechanical means? I am pretty sure the ATF deamed any sort of electrical or mechanical automation of trigger components a machine gun… I’m interested what product “purpose” they got this one approved under. Or if they claimed somehow it was not a trigger at all lol

    1. Its useless crap designed to take your money…

      1. So it’s like a wife then???

        2. Go with that Corvette you’ve always wanted instead, it’s cheaper in the long run.

      Long story short- it uses some BCG recoil energy to push the trigger forward. So if you keep squeezing, you get an (essentially) full-auto gun which doubles as a finger massage.

      The finger massage only happens with the safety in the ‘full auto’ position. In the ‘semi auto’ position it’s a standard semi auto 4.5lb trigger.

  10. Those were some tactical operators acting tactically using some fast tactical triggery.

  11. Basically it’s a a one pound trigger pull.

    And if you use it in a normal home defense situation you would probably be fucked.

      Home defense? Operators who tactically operate in tactical operations don’t care about home defense!

      1. No shit. And they’ll have a full-up M-16/M-4.

    2. What if you use it in an abnormal home defense situation?

      1. Well if it is the Fibbies and their minions, you are fucked already.

        If it is zombies then the world is fucked and just trying to take you with it.

    Ahh trigger kick back where have you been? Mac 10 semi are great for that same effect, your finger will move forward whether you want to reset or not.

  13. pretty sure it acts like a normal trigger in the semi position but hen you flip it to the auto spot it make the trigger fire when you release as well as when you pull. the atf say fullauto is anything more then one round per trigger pull, not pull and release. only time will tell

      double no, it has a a positive reset pressure that is a higher weight than the trigger pull, also the fire on release has been approved in ATF letters before, I will link below. So with a pull weight f 1lb and reset of 4lbs you just have to apply any pressure less than 4lbs and over 1lbs and the trigger will fire immediately upon reset.

      Heres the trigger letter

  14. If I understood correctly how this was working, I think it is a great technical achievement !
    Not sure if it’s REALLY super useful (and legal compared to a shoestring), but I appreciate the technical part!

  15. Would this be significantly different if something else that was not the trigger pushed your finger forward and off the trigger so it could reset?

    That’s the point of the slide-fire stocks. The whole gun recoils into the stock, and part of the stock keeps your finger from following the trigger to the rear, allowing it to reset. The gun is then pushed forward by your support hand, bringing the trigger to your finger.

    So, as a next step, instead of the whole gun recoiling, instead if you have some kind of guard, mechanically separate from the very thin trigger but covering it on both sides, and part of the recoil energy of the bolt carrier group pushes that guard forward, taking your finger off the trigger and allowing it to reset. As the bolt goes forward again, the guard retracts the fractions of an inch necessary to re-expose the trigger.

    As the next step, you’d have this thing, that just pushes the trigger forward using the recoil energy of the BCG.

    So, the way I’m thinking, if the this thing gets re-classified by the BATFE as a machine gun component, we’ve got many different options that can implement an ‘augmented semi automatic’ that is distinctly different than a fully automatic trigger package.

    Eventually, someone is going to figure out that they’re missing out on $200 tax per slidefire stock and trigger group because the purchaser really wanted a select fire weapon, but the Hughes amendment and the stupidly long approval process for Form 4s made that impractical. They’re also missing out on the ammo excise taxes that could be used for conservation efforts because these things make a brass rainbow. Who am I kidding, nobody in government service is going to figure that out that has the authority to make the changes. That would require them to realize that what they’re doing now is useless.

      Someone needs to explain shoulder bump firing to all of these Slidefire and “leet” trigger types. With a little practice, this is what you can do:

  16. From TACCON:

    The 3MR is a drop-in 3-mode fire control system with Safe, Semi-Automatic, and Tac-Con™’s patented 3rd Mode. The 3rd mode has a positive reset that dramatically reduces the split times between shots. The positive reset characteristic is achieved by transferring the force from the bolt carrier through the trigger assembly to assist the trigger back onto the front sear. As a result, this gives the firearm the fastest reset possible. Both semi and 3rd mode positions exhibit a non-adjustable 4.5 pound trigger pull weight. Why 4.5 pounds? Because most law enforcement agencies limit any trigger used for duty to 4.5 pounds and above. Extensive testing done by Tac-Con™, the ATF (BATFE), and professional shooters have proven that this is the fastest semi-automatic trigger in the world. The 3MR is ATF approved and is NOT a NFA part. Each trigger is accompanied by a copy of the ATF letter. This is not a bump fire system. The shooter must pull the trigger once for every round fired.

  17. “The 3MR is ATF approved and is NOT a NFA part.” As of now. Be careful how you purchase it.

    ATF approved doesn’t mean a damn thing. It’s sort of like having David Hasselhoff sign your basketball.

    1. Some Dude Avatar

      Your life is just plain depressing if a basketball signed by Knight Rider wouldn’t give you at least a little joy.

      I’m sorry, bro. Please get help.

  19. What’s the cost, or if you have to ask you can’t efford the ammo.

  20. $495? Nope. Maybe for $200 but that price seems rediculous.

  21. Sledgecrowbar Avatar

    Yeah, for $500 I can do without it. When it drops to half that, I still have to think about whether I want that which is functionally an ammo waster, or to finally get a Geissele for my tack driver, which is a legitimate upgrade.

  22. Sledgecrowbar Avatar

    Apparently it still has a mil-spec 4.5-lb pull weight, but it looks like the disconnector pushes on the back of the trigger when the hammer resets and that resets the trigger. Genuinely clever idea, but I can still totally wait for the price to fall. I think I’d buy it for $125, maybe $150. $175 is too close to a Geissele.

  23. Listening to the rifle fire I cant hear a very fast rate of fire. Movie was impressive but not enough for me to buy it for $495. Really I can’t see using it at all. Tearing into the inside of a weapon is pushing to have problems with the ATF and something I just do not want to do. Leave it alone.
    Fast firing can be done many ways. Bump firing is more like idiot firing. The gun barrell moving up and down and left to right you’d be lucky to hit a brick wall at 30 feet. The only thing it has is the sound effect of full auto. bump triggers seems to be the only thing that most people know how to make nowadays.
    I did see an article about a new trigger coming on the market and a friend showed it to me in action. He got it from a text message that had been sent around in Alabama. The phone movie was a test firing with sound. They say “double shot” and you hear what sounds like one shot with an echo. Then he says “full auto” and it spits out 12 shots like lightning. It seemed to cover the trigger and had it’s own trigger or triggers that was very fast. I put the movie on a slow motion program and counted the times of the shells ejecting and it was upwards of 13-14 per second. It was a Ruger 10/22 firing. None were under 10 RPM. I watched the barrell and saw very little movement so it must be accurate. They were holding the rifle in the normal position so it was not bump firing. Don’t know the details of when or if it’s coming out. Friend said he heard it was less than $80. I’ll recognize it if I see it for real.
    Might give it a try.

      That new trigger you mentioned sounds interesting. If you can send me the video or a link to check out that would be awesome.
