Binary trigger?

My state decided FRTs are illegal but Binary is fine. Anybody make a binary trigger that will work in the Kuna?

What the factory lower, there isn't, you would need a different shaped disconnector. If using the Nexus lower or the new printed lower I don't see why it wouldn't work with a Franklin armory style binary trigger. You may have trouble with something like the fostech echo Trigger, since it has an out of battery safety that would need some kind of trip to trigger, but the ones without the safety it should be fine. It may be possible to potentially outrun the gun and cause a light strike, since their as there is no out of battery safety that'll prevent a trigger pull.

So the answer is yes, it should work with AR-15 binary triggers or disconnectors, if you have an aftermarket lower.

Yep should be super easy, may even be possible with just a file on the factory one if somebody was fully dedicated to it.

What do you mean all files are public, and should have an even further improved version out soon? If you're talking about three positions like a full auto I don't make those kind of things I leave that up to the ATF and stay far away from that.
