Auto-sear question

[riderr]

I am a little confused by the statement below. Politics and labels aside, but in order to put in an auto-sear into a commercially sold AR-15 lower you have to drill the hole, insert the auto-sear, but most importantly, change the trigger group, since the commercially available ones are not select- or burst-fire.

Am I wrong?

Also, if a plastic auto-sear gets constantly rubbed by the metal trigger, it will be shaved off quite quickly.

Adding an auto sear to a semi-automatic AR-15 takes a matter of minutes, says John Sullivan, the director of engineering at Defense Distributed, a DIY gunsmithing and gun access group. 3D-printing the auto sear itself would take around 10 minutes, Sullivan says, given that it's less than a cubic inch of material.

There are drop in auto sears that do not require holes drilled as well as lightning links. But the links need a special bold carrier. It was first used in Colts but they stopped making them. Some lowers also are not drilled down to allow any drop in stuff, the "shelves" they are higher than Anderson lowers.

But it still requires a full auto trigger group, right?

Good morning ATF.
How"s the coffee today?

[tabascoz28]

No, but your rifle is always full auto or safe from then on. You can't use a selector on these drop in devices. Turn on your VPN and search DIAS or Lightning link. Information is not a crime.

Besides the stupid comment, did you get a chance to read the article?

I am on VPN Already searched, but still confused by the article that a plastic sear will withstand the rub from the metal M16 hummer. I seriously doubt that will work for more than one mag

Not something I'm going to look further into, but there are people making coat hanger DIAS too. It's just a machine part....

I afraid that, yes, you are wrong.

According to your comments, I think that don't understand the difference between an "Auto Sear" and a "Drop-in Auto Sear."

The "Auto Sear" conversions require drilling the third hole in the lower receiver. They also require that the aft end of the lower receiver be milled out to full width.

The "Drop-In Auto Sear" does not require drilling the third hole, or any milling. The sear assembly has two parts. The housing rests in the milled pocket of the receiver and the hinged sear then functions the same as if it was riding on pin in the third hole.

"Drop-in Auto Sears" are very dangerous legal territory. The "Drop-in Auto Sear" is currently treated as being a machine gun, even if possessed alone. Please refer to BATF Ruling 81-4: https://www.atf.gov/file/11236/download

Nope, it's not "just a machine part." It's the legal equivalent of a "Machine Gun."

Please refer to the BATF ruling cited above.

Thank you. Admittedly I have gaps in the grey areas of the law, but I am a quick learner. Obviously, it wasn't my intent to cross the line, I was just confused by the statement made in the article.

I think the only advantage that the drop in auto sear gives you is that you don't have to drill a hole in your lower receiver and that it is easily removed. I'm guessing that you would need to remove the disconnector and would still need the M16 bolt carrier and hammer. The AR would not function as a semi-auto with this setup.

I remember, years ago, seeing the real auto sear kits at the local gun shows for $50. They weren't hiding them. They were right there on the table in plain view. Easy for the ATF to see. I almost bought one but wasn't sure what the legality of owning one was and decided maybe it would be better if I kept walking. It would have just gotten me in trouble.

Edit: Just read the article and checked out the website out of curiosity and was surprised that it still existed and these things are still seem to be available. Or, maybe it's part of an ATF sting. Pretty funny what people will do to get around the law. The article was FOS in regards to the Boogaloo boys inciting violence at the 'peaceful protests'. They may have played a small role in the violence but was by no means the cause of the violence. The left wing news media is out of control. I know, preaching to the choir.

Yes - you'll need to work on your control to withstand more than 1 mag dump from that hummer.

Cmon that's a real Freudian slip the U is too far from the A for it to be a typo.

Y'all know that you can print metal alloys nowadays?

I'd never do it because I don't own guns. Hearing "bang" scares me.

Look up "swift link". Printable or made of wire. Caveman can do it.
