How does this work? 1 trigger pull gets 1 round and the release gets a 2nd?

If so, I don't want to be the test case since it could be considered automatic...
Title: Re: New AR Binary Trigger
Post by: suka on March 21, 2016, 11:53:54 PM
Single action of the trigger as ruled by the ATF.

one action is pull another action is release. thats 2 actions.

automatic fire is one pull to maintain a continuos operation (one action) while releasing  the trigger (2nd action)  stops the firing  operation. 

(make sense)?

Two problems with that. What happens if you fire 1 round but then don't want to fire the 2nd round? Seems dangerous to be committed to the 2nd round when the situation might change.

The other is in the wording of the Hawaii law A single function of the trigger might be read to mean a complete cycling of the trigger both pull and release which would then classify the firearm as a automatic firearm regardless of what the ATF says. I wouldn't want to be the test case for that.

""Automatic firearm" means any firearm that shoots, is designed to shoot, or can be readily modified to shoot automatically more than one shot, without a manual reloading, by a single function of the trigger. "

I would say 1 function of the trigger is the pull and another one is a release.   So i think it should be fine to own.

The safety selector would have "safe", single shot mode and binary mode. According to the website, if you fire a round in binary mode you can negate the second shot by switching the selector back to single shot before releasing the trigger. I would still release the trigger with much caution.

A single function is PULL, a second function is RELEASE.. Thats TWO functions for 2 rounds.

I wouldn't chance it.
To me a single function is the complete cycle, so trigger pull and trigger release. The trigger is spring loaded so it is going to return automatically, you aren't forcing it to return. 

Realistically it probably will never come up, but I won't chance it for a product I don't think that great anyway. Take the risk if you want but I think people should be aware this is in a gray area.

dude, it's not a gray area
the ATF defines each action to be a single act

Once the ATF approves and has a letter of approval its basically set in stone. This binary trigger is 100% legal.  Unless a state or the fed bans it specifically.

Both Laws are written exactly the same


26 USC 5845(b)
Machinegun
The term “machinegun” means 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.

HRS 134-1
Automatic firearm
"Automatic firearms" means any firearm that shoots, is designed to shoot, or can be readily modified to shoot automatically more than one shot, without a manual reloading, by a single function of the trigger.

Ok, fair enough.

But my follow up question is this: Do you trust local prosecutors to interpret the law in line with the way the feds do?

Our 2nd amendment in Hawaii is worded the same as the US constitution with one small word difference yet federal gun rights and Hawaii gun rights are very different.

Like I said, I don't think it will ever come up, but just want to throw that out there for consideration.

Federal ruling > Hawaii ruling.  If the fed makes a rule and the state makes a rule against that rule.  The federal rule wins out always without question.

Not quite how that works. If that logic held then no state could make more strict gun laws than federal gun laws. Example, silencers are legal to purchase with a federal tax stamp, but Hawaii says no.

Silencers are legal but are regulated by federal law and on a state-by-state basis. (National Firearms Act” (NFA))  Because of this states are free to do as they please.  Our state chooses to ban it.   Like comon a quick google would prevent all your false statements.

You didn't say anything contrary to what I said. Hawaii makes gun laws in addition to federal gun laws. Just because you see the same wording does not mean you see the same application.  Welcome to liberal courts. Maybe you need to use google.

As I stated earlier to your email inquiry that the Attorney General is unable to provide legal advice to the general public pursuant to Chapter 28 of the Hawaii Revised Statutes.  I'm not able to interpret statutes or provide a legal opinion for your issue.  If you need further assistance with your specific situation, an option would be to seek the aid of an attorney who is familiar with Hawaii's firearms laws.

Installed and tested now at Schofield.   

The Semi setting I was have a trigger reset problem which I will email FA about.

However on the binary setting.  Worked like a charm.  20 rounds goes very quick.  Lol

Basically full auto if not a little faster.  2 round bursts are awesome because it is so fast.
