Florida resident Kristopher Ervin was arrested in early March 2021 as part of a joint operation by agents with the Bureau of Alcohol, Tobacco, Firearms, and Explosives and the U.S. Postal Inspection Service. (Yeah, that’s a thing.)

The ATF claimed Ervin sold auto sears -- components used to convert semi-automatic AR-15s into rifles that are fully automatic and fully fun...but also illegal without the proper paperwork.

So let's take a look at this case. We’ll answer what an AutoKeyCard is, find out why the ATF is so upset over it, and break down similar cases.

Editor's Note: Updated April 25, 2023, with new information regarding the trial. See below.

What is an AutoKeyCard?

In short, these were business-card-sized metal bottle openers sold through Ervin’s websites AutoKeyCard.com and AutoKeyCards.com.

(Well, they were sold there before the Feds shut it all down.)

The cards came laser engraved showing the parts of an AR-15 automatic connector, commonly known as a “lightning link.”

The lightning link, when assembled from its separate components and installed in an AR-15, could convert it to full-auto without any additional modifications to the firearm.

Because of this, the ATF decided the cards were close enough to auto sears to fall under the machine gun restrictions under the Firearms Owners’ Protection Act amendment of the National Firearms Act.

Therefore, ATF and U.S. Postal Inspection Service agents purchased a few of these bottle openers as part of a sting operation.

USPS Inspection Service...who knew that was a thing.

Agents later determined Ervin was illegally selling auto sears since customers who purchase the keycards would be able to take the product and convert semi-auto AR-15s into fully automatic rifles.

Investigators with both agencies arrested Ervin and seized his websites. 

But this begs the question, what does this mean in the grand scheme of things for the gun industry and owners?

What’s the Big Deal?

Aside from the fact the ATF hates anything fun (i.e. alcohol, tobacco, and firearms), the agency took issue with the AutoKeyCard because the product could potentially convert a semi-auto AR-15 into a full-auto.

ATF Meme Guy
ATF be like...

As part of its findings, the ATF reported that “an ATF expert analyzed one of the devices that had been purchased undercover and was able to convert an AR-15 style firearm into a machinegun by cutting out the etching for an auto sear using a commonly available tool and then inserting the auto sear into the firearm.”

Based on this determination, the AutoKeyCard fell under the NFA as a “machine gun.”

ATF, why won't you let us have fun?

The NFA also bans civilian transfer or ownership of machine guns except for those already legally owned at the time the law went into effect on May 19, 1986.

According to the ATF, this meant Ervin was effectively selling machine guns in violation of the law.  

For those of you who have looked into buying a machine gun, or even just a suppressor, you will know the lengths that you need to go through, in terms of time, money, and paperwork, before the ATF will allow you to own one.

Rifles Only HAD Suppressor Cover
Even suppressors are subject to the ATF's rules.

It shouldn’t be a surprise, then, that the ATF would jump all over someone for selling an item that could potentially be used as an auto sear.

Have There Been Similar Cases?

The current law -- in this case, the Hughes Amendment of the FOPA -- bans civilian transfer or ownership of machine guns, except for those already legally owned at the time the law went into effect.

In addition, the broader NFA restricts the manufacturing of certain types of firearms, including machine guns.

Timothy John Watson v. United States of America: Portable Wall Hangers

In November 2020, the FBI arrested Timothy Watson of West Virginia for selling “portable wall hangers” on his site portablewallhanger.com.

Watson for, among other things, illegally manufacturing machine guns and selling them.

But Watson’s creations were 3D-printed hangers. These featured a hook portion that could detach. This portion just so happened to be in the shape of a drop-in auto sear capable of converting a semi-auto AR-15 to a full-auto.

Imagine that!

The argument in the portable wall hanger situation, of course, would be that the product is a wall hanger. And it’s unfortunate that people found another use for it as an auto sear.

For the wall hanger case, there were plenty of discussions on forums and social media about ways to use the wall hangers. Such as how to use them on “Armalite walls.” 

Not to mention, Watson actually did manufacture these items ready to slip into AR-15s for conversion to full-auto.

So, this is probably a pretty weak defense for Ervin to adopt for his own case.

Defense Distributed v. U.S. Department of State: 3D Printed Files

On the other hand, the Defense Distributed case may provide a little more hope for Ervin. In this battle, Defense Distributed provided files for 3D-printable firearms, including the Liberator pistol.

While Defense Distributed was a licensed firearms manufacturer, they didn’t sell 3D-printed products. They just offered up their 3D print files freely – available for anyone to do with as they pleased.

The argument for Defense Distributed is that they simply exercised their First Amendment right of free speech in sharing the 3D printing files.

Ervin sold his AutoKeyCards with the designs of the lightning link components engraved into the metal but did not actually make the components himself.

It would be similar to providing a drawing of the lightning link on a piece of paper that someone could choose to use as a stencil or just as a cool drawing.

Gun Drawing
At the heart of this defense, does drawing or outline leave someone accountable for what another does with that info?

But using this as an example might also depend on how much extra work is required to go from the AutoKeyCard to an actual lightning link.

That would be the difference in deciding if Ervin was actually making the lightning links or just engraving a design on a piece of metal.

Of course, it’s important to note that most people who go up against the government either enter a plea deal or manage to win a settlement with the government.

People rarely win a case outright against the government.

The Verdict

On April 21, 2023, Ervin and Matthew Raymond Hoover (a YouTuber who talked about the device on his YouTube channel) were found guilty of a few charges related to the AutoKeyCards.

In particular, the trial resulted in guilty verdicts for “conspiring to transfer unregistered machinegun conversion devices” for both men, with Ervin being convicted of seven counts of transferring the auto keycard, three counts of possession, and one count of “structuring cash transactions to avoid currency transaction reporting requirements.”

For this, Ervin could face up to 110 years in federal prison, while Hoover could spend up to 45 years in prison. Sentencing is scheduled for July 31, 2023.

Final Thoughts

TL;DR: The Auto Keycard was a sorta bypass to convert semi-auto guns into full-auto ones, according to a jury. Ervin was found guilty and faces up to 110 years in prison.

  • I heard no one, including the best and smartest at ATF, was able to use the drawing to make a functioning auto sear that actually functioned. If it had to be modified at all( by experts with the power and deep pockets of federal government)the etching was a scam. The question really becomes, did Hopver believe he was marketing a product that actually could make Ar-15 go full auto.. if so would he be so public advertising it ? I believe he is guilty of perpetrating a scam. Turn on tv or youtube , see nothing but scams being advertized in every commercial. Scamming openly online an obviously illegal auto sear key as a working as advertised product was crazy and very dumb. Stupid is as stupid does. I am in favor of showing him leniency if he learned a lesson, for his wife and child's sake

    Some of the comments below buy into the premise that machine gun laws are lawful in the first place. Then they proceed to split hairs with the ATF. To me the 2A says otherwise and nullification lets me make that determination if I am ever lucky enough to find myself on one of these jury's. Following the 2A as written by our founding fathers is so much simpler then debating over the details.

    ATF bought them, cut them out along the lines, and they didn't work. They immediately jammed. ATF had to considerably modify one to get it to partially function. This testimony was stricken and barred by the judge. Bottom line: they were drawings on a piece of flimsy, thin stainless steel. ATF was out to make an example of him for having publicly denigrated and derisively scorned them repeatedly on his YouTube Channel. It was Lawfare Revenge.

    Greetings from GER, this is even more BS than we have over here.

    • Dana Fargo

      I hear ya...BS or not it's still one the many laws within our government to protect and be fare to ALL American citizens.

      Everything short of rape, armed robbery and murder is still legal in the USA.

      All we have to do is play by their rules. Up to and including 50 cal BMG are all legit to own. Albeit lots of paperwork, time and money. But just bid your time...you'll be notified when to come pick it. All legal!

      They do put a stop to missiles and rockets. (you can own the launcher though)lol

      Plastic explosives and dynamite are fun too! Over counter sales in some areas. (mining supplies)

      What other country on the planet, that you know, let's freedom ring like that!

    I think the government is in overreach mode but once again, you can't be responsible for what someone else is doing with the card, parts, etc.., because I could design a round ball and say it's a toy and someone else could take it and use it for bomb stuffing it with explosives and blow something up, but I'm held responsible for it!!! That's ludicrous!!! Now on the other hand, if they were making and selling and advertising it as a conversions tool to make rifles automatic that's something different, which doesn't sound like what they were doing... As far as I/We know they were just making bottle opener's with a design engraved on them, which is not there fault if people used them for something other than what they were made for... That's a Not Guilty!!! But I bet the jurors were, some/all of those people that have been spoon fed the BS, that we have to many guns(unless you need one), in America!!! One thing for sure and is a definite FACT..! Guns don't kill people, People do! So you wanna combat who gets the guns, period and for America itself white folks can go buy guns uninhibited and those are who are doing all these mass shootings, school shootings, club/store/church/racist shootings, and statistically should be outlawed from owning them!!! And that's another FACT!!! They can have records which prevent them from owning a gun and walk right into a gun store and buy one w/o incumberences. That wouldn't happen with any people of color ,period.. trying to buy a gun! Stick to the Facts!!!

      I think the big issue here is the manufacturer of the autokeycard basically paid a YouTuber to advertise it on his channel as a device that could turn an AR-15 fully automatic.

      There was a lot of money that changed hands, and even a Louis Vuitton purse. Think if you remove that fact then it's a not guilty but with that fact, you can't really say that it was marketed as such. I dislike the ATF as much as the next gun enjoying, dog loving American but this guy knew exactly what he was doing.

    IMHO it would depend on the extent to which the outline of the lightning link is ‘engraved’ on the card. If the necessary parts could be snapped free of the card like the parts of a plastic model and employed successfully with little or no additional work to the pieces then yes, they were selling machine gun parts and should be sentenced in accordance with the law. If the pieces had to be cut free from the card with a tool then the only thing they are guilty of is selling a laser etched diagram of a gun part that was probably open sourced from the start.

    If the latter is the case then their conviction represents the successful criminalization of ‘art’ and that is a seriously slippery slope and a truly screwed up precedent.

    One problem I have (even as a gun owner) is WHO in their right mind would spend $109.00 for a can opener?? Come on folks.
    ...
    • Diggity Dave

      People spend more than that on toys, perfume, a wallet and even on half empty bottles of Evian water.

      If I were buying a machine gun or machine gun parts, especially unlawfully, I would expect to pay a lot more than $109.00 plus tax. Wouldn't you?

      According to the ATF's argument all manufacturers and sellers of sheet metal or even tin snips are selling machine guns or machine gun parts.

      Furthermore, they aren't even operating from statutes. These unelected bureaucrats just make up whatever nonsense they want and then enforce it as though it is law and the courts just go along with it.

    You should familiarize yourself with the particulars of a case like this before writing an article attempting to explain it.. Specifically, the Jury questions. We are living in a bananna republic. The court may have rendered a guilty verdict, but the jury was specifically instructed that whether or not what the defendants sold was or was not a machine gun was not in question. All of the government's witnesses admitted that what was sold could not be used to make a functioning firearm, much less enable full auto. The defense was impeccable, and yet the judge chose to instruct the jury to deliberate in a way that ignores the subject matter of the case in order to get a guilty verdict.

    a block of aluminum is a firearm(according to the ATF/E)

    cold roll steel must be considered a firearm also.

    sheet metal for stamping?

    these bureaucrats need to be reigned in, prosecuted for violating people's civil rights and constitutional rights.

    the politicians that support the bureaucrats should be arrested and tried for sedition.
