I recently received written BATFE FTB approval of a prototype selectable dual mode trigger system. I have patent pending status on the system as well. This trigger uses a selector to switch between two modes of fire, one mode being normal semi-auto, the second mode firing a shot on both the pull and the release of the trigger, essentially a two shot burst.

At this point, it is not in production, it is simply a one off prototype I built with hand tools and a Dremel that has received Firearms Technology Branch approval. I decided to "unveil" it so to speak to see how much interest is out there for such a system. I am not sure how much real world practicality it has, but it sure is fun.

Here are a couple videos, one with .223 upper, one with .22LR upper

I will post more videos in the future.
 
I've seen trap shotguns with a "release" trigger. It doesn't fire on the pull stroke, just when you let off. They can be a bit disconcerting if you are not used to them.

Honestly, as an RSO your idea scares me a might.
 
+1 on a release trigger.
They were hot in trap shooting at one time.

But it still only fires once per trigger pull.

Call me a skeptic if you must.

But somehow, I just can't imagine the ATF signing off on one that fires twice per trigger pull!!

That is a select fire trigger, no matter how you slice it.

Yes, I am familiar with those shotgun release triggers as well. With my system, if one is using the dual fire mode, one would immediately release the trigger in one fluid motion for two shots. If he wanted to shoot single shots, the selector would be switched to that mode. It is not idiot proof, but then neither are firearms themselves.

They did sign off on it, I have the letter in my safe. I would not go posting this if they hadn't, believe me !
 
So what does that approval mean? That you could sell it without NFA issues?

Not sure exactly how I feel about this sort of product from a practical point of view. But it's at least fun for the range.
 
i'd like to see a vid with a close up of the trigger action. in the .22 upper vid, i can't see any movement in the trigger finger. could be just me though.

:D


That is a very cool idea and I congratulate you on making your idea a reality.

I bet you could keep up a pretty steady rate of aimed fire with that trigger set-up.


Now go make one for my FALs and you'll get your own "Real men of genius" song, and I'll buy the beers while we listen to it...
 
Paintball guns have used the 'fire on pull, fire on release' system for years to skirt the 'no full auto' policy most organized parks have.

Really (REALLY) surprised the ATF went for that, since it's one pull of the trigger, AND IT'S SUBSEQUENT RELEASE that fires two shots, rather than two pulls of the trigger.

Certainly has a place, if it's legal.

I see a bright future for yourself. This would be popular like the slidefire, only a bit more practical. I would definitely find some investors, because this will be a great product to sell. I think it would go across the board to different breeds of shooters as opposed to the slidefire, which had more of a novelty effect, cool, but it wasnt exactly cheap to own or shoot. if you could market this in the $50 range, I could see high volumes of sales, especially in the AR fan club.
 
Very interesting.

You wouldn't happen to be the guy behind Tactical Fire Control (http://249development.us/johnsann/Tactical_Fire_Control_wp/) would you?

Apparently they have an AR trigger that does something similar, but I believe their trigger is reset by the bolt carrier moving forward. Then you can just ride the trigger with your finger and get a pseudo-full auto fire mode. It has the folks on ar15.com all abuzz:http://www.ar15.com/forums/t_3_118/627922_Tactical_Fire_Control.html&page=1

They're trying to organize a group buy for the thing, but apparently TacCon is a small company and still trying to get their act together. The only info we've gotten so far is their MSRP is $500, so if you can beat that, you may have a winner on your hands.

I would definitely be interested in one of these triggers once you get them to market (or hell, PM me a price on a prototype and I might buy one sooner and give you my thoughts on any areas that could be improved ;) ). I've been thinking about this kind of FCG since I found out about the ATF Approved Mini 14 trigger groups that do roughly the same thing (minus the select fire capability) but I don't have the engineering background to be able to produce something like this myself, so I'm glad you've been able to do it.

What is your expected/target MSRP? If you can get it to a price that is comparable to other aftermarket triggers, I think you'll have a good chance of attracting a following.

And just to clarify, you have a tech branch ruling, and not just an opinion letter, correct? Any chance we could see the letter and/or diagrams and pics of the trigger group (if you already have the patent in process)?
 
The BATF FTB had in their possession and examined my prototype, they ruled it not a machine gun and provided me a letter stating that. I have had patent pending status on this for nearly two years, and just recently received a favorable ruling from the BATF. They did not approve my first prototype I sent them, but I am not going to elaborate any further than that at this time. The patent should issue within the next six months. The drawings and patent specs will be available at that time, maybe sooner.

I would like to see this in production and available on the market, not sure how that may occur at this time. I have a full time career and tinker with firearms on the side. I am weighing my options and trying to see what demand might be out there before proceeding in any direction. I could hand build them one at a time, but would have to charge a fair bit to make it worth my time.

I really like it, and have a lot of fun with it. With the flip of a switch, I have nearly full auto rates of fire.
 
Make a kit for an AK and I'm interested!

It's once per trigger action if I remember correctly.
 
I've heard of a legal kit that did this for the Mini-14, years ago. I read about it on this forum, in fact. "Turbo" triggers like this scare me because it forces you to fire that second shot. It's a major safety issue. If you're shooting at the range and there's an emergency (like some dolt walking forward of the safety line) and they call ceasefire when you've got your finger back, what then? You cannot put your gun down without firing an extra shot. They also double the chance of a tragedy during an accidental or negligent discharge. And let's not forget the legal nightmare of using such a gun in self-defense.

They may be legal per the ATF, but they probably shouldn't be, purely for safety reasons. They make it so you cannot stop shooting at the precise moment you want to. When using this trigger system, you are NOT fully in control of your firearm. You control whether and when you make that first shot, but you are committed to making the second shot, safe or not. It may be a legal product, but it's a dangerous product, one I would not even consider using.
 
Warden wolf brings up a point.

If you are shooting, and stop with the trigger held back can you flip the selector back to semi and have the trigger reset normally? (i.e. not fire) Or are you stuck fireing that second round once the trigger is pulled?
 
You can easily tell that it is the personal manipulating it that is making it shoot that fast....the rate of fire is very sporadic. I don't mean that these parts don't work...they do....it's just that it requires more human input to get the result. The TFC appears to reset the trigger automatically and then I assume it's a light trigger pull that you can set off by keeping rearward pressure on the trigger, essentially bump firing. This one still requires human input to fire each shot. The trigger has to be pressed to fire one shot and then released to fire one shot...that's both human input, not mechanically controlled. I find the designs people come up with interesting and I always check the stuff out...but I would never consider buying any of it myself.
 
I'd like to see the actual letter. You can white out name and address for privacy.

I'm pretty sure that in the double shot mode that you aren't taking the time to carefully fire rounds. I'm pretty sure you are letting it rip so that second round is off before your brain processes "cease fire!"

I'm also sure that unchambering a round will be the best bet either way while holding the trigger back.

And let's not forget the legal nightmare of using such a gun in self-defense

That's about as bright as using a slide fire stock for home defense. Play stupid games, win stupid prizes.

Avoiding the argument about the government protecting people from themselves...
I think the trigger group is better thought of as more of a "2 round burst" trigger as opposed to "pull, BANG.........release, BANG". With that in mind, if the second shot is uncalled for, the first shot probably was too.

And if you're in a position where you don't want to fire the second shot, drop the mag and clear the chamber while you have the trigger depressed. That way when you release it, you're just dry firing on an empty chamber.
 
I, for one, think it's fascinating. USPSA, 3-gun matches, etc., better get on the stick and outlaw these things before they get started!
 
They may be legal, functional, and entertaining, but if I was a gun store owner I would never invite the liability of selling a rifle equipped with one.
