New dual mode trigger system BATF approved !!

As the OP mentioned, his first prototype wasn't approved. And he hasn't said that you can't flip the safety on and it won't fire.

You guys do use the safety when someone calls cease fire, right?

Remains to be seen how this operates. Since decockers can drop the hammer and put a pistol on safe, then there is the possibility this will, too.

Entirely the reason to keep a bit mum on it. No patent yet. What it does prove, once again, is that a lot of the great inventions of our day are just existing technology applied in a different way.

You don't have to like it, but on a gun in a cheap surplus caliber, it will sell like hotcakes. Lots of berm shooters would line up for it.
 
IIRC, the BATFE deal is one shot per motion of the trigger. Pull, bang; release, bang: Two motions.

If one can use the selector AFTER the trigger is pulled but before release, it would be much more safe than if you can't make the change. There are unintended scenarios where a dangerous situation could occur.

They've allowed other aftermarket triggers that do this. However I don't think they had a way to switch to single shot.
 
Switch to single shot mode?
No I mean after you've fire one shot you realize you only want to shoot once. So now you're holding the trigger and fumbling around with some sort of selector switch...hoping you actually get it flipped right (or that it flips at all between rounds) in that mode.

Sounds like a good way to shoot something you don't intend!

You just unchamber the gun, it's not hard to do. I'm pretty sure that you would end up releasing the trigger before you realize what fire mode you're on.
 
You guys could wait for the inventor to answer the question before you all get too far into the "Wait! What if...." land.
 
Not sure where most of you shoot, but the range I am a member of has a 5 second rule on the multi-person ranges. This trigger in fun mode would be a no-go. But at the full-auto stall this would be a blast. It looks like there is less moving to get the desired effect as opposed to the slide-fire. My one question is: have you tried this in an AR of 5.56/223 or just 22?

One of the videos in the OP is with .223 upper, the other is with a .22lr upper, according to the OP.
 
Very interesting. I would be curious to see how the internals work. I've seen the fire-on-release mod for the Mini 14 that works by just opening up the gap to the disconnector. Never thought that was a great way of achieving this effect, but at least the ability to switch back to single mode is a plus.

One thing that could be done regarding the "what if I don't want the second shot" concerns is to make the trigger a ring instead of a single blade and make the return spring more of a toggle that would either hold it forward or back. That way you pull it back, push it forward, but could let go and set the gun down with the trigger in either position without it firing when you let go.
 
If using the trigger in the "third" mode, the shooter must realize that every shot will be two shots and must plan accordingly. Except in rare cases, if it's unsafe to fire twice, it's unsafe to fire once. If it's one of those rare cases you can only fire one shot, don't use the "third" mode
 
There is a web site with a picture of the drop in unit. No ring trigger, but their is a tail extension out the back that apparently engages something, and the safety lever is part of the kit.

Not normal for the usual trigger, if the cost could be trimmed, it would be. Simple business decision, therefore the safety is a critical component.

Thanks for the quote, strangely, no one has yet directed me to a certified instructor on "Concealed Carry in the Crapper." :rolleyes: It's relevant because we seem to get a lot of speculation about something, but very little in the way of grounded knowledge.

It's much more fun to guess than know the facts, apparently. :evil:
 
From the ATF website:
U.S.C. § 5845(b), defines the term “machinegun” as:
… any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.


Not to be a party pooper, but if ATF receives flak from above, they'll just redefine what a "single function" is, or some such male bovine excrement.

It's happened before and it'll probably happen again.
 
UPDATE: I am working with Fostech, my patents have been assigned to Fostech, and they are releasing the trigger as the ECHO trigger. It should be hitting the market by mid year. I know it has been a few years, but wanted to update the thread.

Here is a link to live fire video of the Fostech ECHO:

Yes, I was aware of the other thread, but did not really want to delve into the question posed by the OP. I wanted to update my progress on my trigger for those interested. I hope you can keep this thread open, as the title of the other thread does not mention what thread is about, and is more philosophical in nature, and think that is a whole different discussion.
 
The first thing someone is going to do is put a bump fire stock on it.
That would easily out run the gun, but it'd still function.

I'd like to shoot one of these before I have an opinion. It sounds difficult to operate effectively, but looking at the video it doesn't appear that way.

For what it's worth, I'm not beyond buying something simply to have fun with. That'd be the only reason I'd buy something like this, for the fun/cool factor not because it's practical.

I'd also rather have one for an AK than an AR.

BTW:
Good luck, I hope you get rich and many people are employed as a result. :)

Yup! No problem! And congratulations on your success!
 
Sounds just like the Franklin Armory Binary Firing System. MAC did a review on that trigger and could easily outrun the BCG; hammer would follow the BCG on a live round but no ignition. How did you alleviate that issue?
 
Cool beans! You hardly ever hear about someone's invention getting picked up by somebody :cool:

I've got a similar idea (only it fires twice over a long pull, allowing rapid "burst" fire if pulled at the proper rate to avoid hammer follow, maybe even a mechanical delay if the ATF is cool with that) that I'm meaning to play with at some point in the future when I've got it drawn up more completely. Purely to get the ATF to approve (provided it doesn't exist) rather than for marketing purposes --way too many fun-gun builds could benefit from a more controllable rapid-fire trigger, as you've no doubt found with your binary system.

Have you tried bumpfiring with it? Someone asked about that three years ago :)p) but it seems like this would be super-prone to hammer follow in practice.
