What the heck is it?

I am not a member.

I think the lightning link was some way to make your semi auto fire fast to simulate automatic fire. I think of a few of those multi burst trigger things have been classified as machine guns by the ATF, California won't let you have one whether they are or aren't considered machine guns by the ATF.

[AJAX22]

Real lightning links are registerd NFA devices. they are machineguns under federal law.

It is a paddle/link which trips the disconect as the bolt moves to the forwardmost position.

don't f with them, you WILL go to jail

LL turns your gun into full auto, and isn't legal unless it was registered like a DIAS "back in the day". Apparently you can make them from a hacksaw blade or something.

I've heard that a properly bent paper clip will do the same thing. Of course, I'm not stupid enough to try it. I won't ever try the shoe lace thing either!

:eek: I already bought it;) For 7500 I rather spend 3 weeks on Maui!

Yeah, I've heard of them. They're not like multi burst trigger actuators - those are more like bump firing. The lightning link is an NFA device which makes the gun fire in full auto by interrupting the disconnector when the bolt returns to battery.

Don't forget credit cards and business cards...

Yea, like some bank would be dumb enough to give me a credit card.

Any idea why there are two disconnectors in there?

[leelaw]

ny idea why there are two disconnectors in there?

Perhaps to allow SAFE-SEMI-AUTO function? The selector has three positions, and the one disconnector looks longer than the other.

My first credit card was almost maxed on my first oll build

How familiar are you with a regular M16 fire control group?

No offense here, but you can't put two disconnectors in an M16 or AR-15 trigger.

The way an M16 works is that the selector draws the disconnector down when in full auto and the auto sear controls the hammer via the carrier.

My understanding is that the way a LL is suposed to work is to just drop into a semi-auto hammer/trigger/disconnector and allow for full auto function.

In other words, safe/full, not safe/semi/full.

The selector being forward in that picture is interesting too.
You can't use an M16 selector in a LL application so why have the M16 selector?

The point is that it looks custom, not just an AR15 that someone threw a lightning link into for instant FA goodness.

I was simply pointing out that the disconnectors are of different lengths, appear to work independently from each other, and the selector appears to operate in three positions.

If trying to answer your questions comes with a rebuttal of being talked down to, then perhaps you shouldn't ask them anymore.

ETA: it looks like the second disconnector has a forward catch on it - 3rd burst, possibly? Maybe it's set for SAFE-BURST-FA

[ar15barrels]

I wasn't trying to do that.

[AJAX22]

The M-16A2 trigger group has a pair of disconnects that allow the the selector to use one or the other disconnector during firing. The selective fire kit as Scott Bell and John Norrell developed it, uses one disconnector that has a notch cut into it preventing the LL from tripping it, while the second disconnect does not have this notch and is tripped by the link causing full auto operation as with the standard AR-15 disconnector.

Its a burst trigger with two different disconectors.

[OCArmory]

There are modified full auto kits that will allow your lightning link to perform in both semi and full auto.

Ah, excellent.
So one of the selectors DOES go back and engage the selector drum.

Correct.

It is a mod that allows you to have none-one-fun capabilities in an AR lower, using a lightning link. This page also has everything you ever wanted to know about the Lightning Link. Personally, I'm fascinated with them. One of the most ingenious, actually-safe, full-auto hacks I've ever seen. Works just like a real auto-sear, but with zero M16 FCG parts.

To the original poster, you can get "50%" lightning links on gunbroker. DONT buy one. California may not have constructive posession laws, but the BATFE will nail your *** to the wall if you so much as even think about building one of these.

Research them, look at the pretty pictures online, but don't buy one.

I used to have an M16 auto-sear on my keychain when I DID NOT own an AR15, just for novelty purposes. As soon as I DROS'ed my first lower I tossed it in the trash, never to be seen again.
