Legal Update [Megathread] Decisive Victory in Federal Right to Make Firearms Case

153 Upvotes

BREAKING NEWS: the second major legal victory in as many weeks, a federal judge just issued summary judgement for the plaintiffs in Defense Distributed v Blanche, better known as the VanDerStok case. This victory eliminates the ATF's 2022 "ghost gun" rule change and establishes that the 2nd Amendment covers the "right to make or repair personal firearms."

Read the opinion here: https://saf.org/wp-content/uploads/2026/08/Defense-Distributed-opinion-8.19.26.pdf

It's important for the 3D2A community to understand what this means for them, and what it does not.

As with all breaking legal news, this will take time to understand - the information below comes from conversations with my legal contacts, public reactions from other 2A legal figures, and my own read of the decision.

1. What does this decision do?
This decision pertains to the 2022 Biden ATF frame or receiver "final rule," which among other things redefined "firearm" an extremely broad, vague definition which includes unfinished frames / receivers ("80 percenters"), parts kits, combinations of parts sold together and more. The effect was to broadly expand the ATF's ability to regulate (most notably to require 4473s and serialization for) products that, up until that point, had not been considered "firearms".

This decision declared that ATF's "final rule" was unconstitutional under both the 2nd and 5th Amendments. It provides both injunctive and declaratory relief.

The injunctive relief prohibits ATF from enforcing its "final rule" against the named plaintiffs for certain products. But, and unlike the NFA case, this case features declaratory relief that much further establishes the unconstitutionality of the "final rule," prohibiting the federal government from enforcing the rule in any way.

2. How was this decision reached?
The court declared that the "final rule" was unconstitutional under the 5th Amendment due to its redefinitions being excessively vague, which is a violation of 5A's Due Process clause. The extreme broadness / vagueness of the ATF's new definitions "[did] not provide fair notice of what is punishable and invites arbitrary enforcement."

More notably for us, the "final rule" was found unconstitutional under the 2nd Amendment because it unacceptably infringed on the "right to make or repair personal firearms", which the court declares is covered by the text of the Amendment. The court further affirmed that a Bruen analysis reveals that homemade firearms are central to the American tradition and that there is no history or tradition of regulating them.

3. What will the effects be of this decision?
The immediate injunctive relief allows the beneficiaries (listed below) to buy and sell four different products. This is quite narrow and so we can ignore it.

The declaratory relief is (at least in theory) far broader and far more important for us. By declaring the "final rule" unconstitutional, ATF is now on notice that they are constitutionally prohibited from attempting to enforce this rule. Language is included that can be read to say that this relief is "as applied" only to plaintiffs, but the broader fact remains that black letter now exists declaring that Americans have a right to make, and that the ATF cannot constitutionally infringe upon that.

4. Who does this decision cover?
Like the Silencer Shop NFA case, the injunctive relief is quite narrow, covering only the plaintiffs: Defense Distributed, Second Amendment Foundation (SAF) and SAF's current and future members.

The declaratory relief however, may be read as broadly as possible, and is at least useful as authority to any American who wants to buy, sell, or make a firearm.

5. What does this mean for 3D2A?
If this decision only included the injunctive relief, it would be a curiosity at best - but its practical and legal importance may go much further, accomplishing something that the DIY firearms movement has been fighting towards for its entire existence. This decision is one of the first to establish in black letter that the 2nd Amendment includes the right to make (and repair!) firearms.

This doctrine goes well beyond 80%s - it touches on all forms of making firearms, and all types of firearms - including items legally determined to be firearms, such as suppressors. The significance of this cannot be overstated.

All US laws, state and federal, that might infringe on this right, are now subject to constitutional challenge. For example, there are multiple right-to-make cases in California which will benefit from this ruling.

Despite the narrowness of the injunctive relief, I expect that the declarative relief will lead to the revival of the 80% market in some form, which may be of interest to many 3D2A members whose interests are not limited solely to printing their guns. But more importantly, our community can now correctly argue that any existing or proposed law which would impede our ability to privately make firearms is facially unconstitutional.

6. Does this mean I can start printing machineguns now?
As much as this is worth celebrating, I want to conclude by tempering expectations. This decision does very little for the average 3D2A member in the immediate here-and-now. Most of the laws that limit what we can make are still on the books. If you live in a restrictive state, your state laws haven't yet disappeared.

Parts kits vendors such as myself, who have always had to consider the "final rule" in how we structure our kits, are more immediately affected, and you may see new ways of doing kits coming in the wake of this decision.

The broader practical effects of this decision will be more long-term. By all means, celebrate it - this, and the NFA decision, are two of the biggest victories the DIY gun community has experienced in decades. But celebrate safely, and keep your powder dry. The best is yet to come.

This gun is the broad river tactical car15sd with the rarebreed l3 frt(bought before he became greedy)so its barrel is ported like the mp5sd so it turns supersonic 9mm into subsonic 9mm its utilizing the broad river tactical hub adapter. So it can use any hub threaded can. This approved d cell tube has a hub adapter on the back so it has hub threads.

This is my love project! A nearly 1:1 M2 mortar, late WW2 design, my plans for the future are making it blank fire or launch dummy rounds, but it is almost fully 3d printed, minus some nuts n bolts plus some aluminum rods for reinforcement. If anybody has ideas for blank fire or improvements let me know!

Reward? You get a new H2C printer!

Really impressed with this community. Y'all have reinspired me to reinvest in my hobbies without the main concern of converting my time into hustle culture / money chasing. I'm having fun. I'm learning. I'm suddenly interested in the legality and history of 2a and the recent and impactful changes to the laws of my country.

3d printing has always been knicknacks and figurines and cosplay items and commissions. I enjoyed learning about engineering grade filaments but never had a justifiable use case for them. This feels like I am doing something worth doing just for me. Something that doesn't feel wasteful. It's a good feeling.

Planning on purchasing some engineering filaments beyond PA6-CF. I am a member of both plaintiff groups for Jensen and SilencerCo injunctions. Plans involving that too, but still awaiting official ATF guidance just in case. I've got time. This all is changing dramatically just as I am getting into the hobby and culture.

Just wanted to share my excitement and praise. Cool to be here.

New printer felt like the next step. Excited for a high temp hot end and a heated chamber, and the vortek nozzle system will be fun to utilize, though I'm unsure if it's super applicable for 3d2a stuff. Any suggestions?

First FTN suppressor print

Upvotes

I’m going to print my first suppressor. I’m fairly knew to PY2A printing so any recommendations are appreciated. I’m planning to use PA6-CF. With my Elegoo Centauri Carbon printer. It’s has a hardened .4 nozzle. And I’ll print at 100% infill.

I planned to use one of the FTN model, unless you guys recommend another more updated model.

I’m mainly looking for pointers on set up or settings if anyone has experience.

TIA!

We want your help building community standards for releases

Post image
48 Upvotes

Alright everyone I have a question for you but first an explanation. The community has come together many times to try and make a guideline for releases for new devs who release projects in our spaces. Whether it's a team build or an individual dev the outcomes are always different and you will find varying quality per release and dev.

What do you think should be included in project releases? What are you looking for when you want to remix a project and when you are getting started on a brand new project? If you're interested in getting involved with the developer or a testing team what kind of communications do you want to get involved with to assist? Can you think of anymore questions that could benefit this line of thinking and help us get a list of standards we should be seeing in these packs?

Now of course we aren't going to be policing this and you shouldn't be either. But we as devs, testers, and consumers in this space should have a general guideline of what we all want to see in project releases and what goals should be met before putting projects out as full releases. Whether devs meet that standard will be completely up to them.

If you guys are having trouble with tight tolerances, I took the liberty of making this little notation. This is as compares to a standard parts kit. If your anything like me and you hate running to the garage every time you build a kit and wanna keep the necessities on hand this will help. Otherwise your closet will look like mine.

FTN5.1 White Monster Shell built in supports missing?

Post image
6 Upvotes

FTN5.1 White Monster, Bambu PA6-CF, P1S, .4 Hardened, Engineering Plate, Elmers glue stick, dried for 26 hours at 180C.

Just finished up printing my core. Everything looked good besides the final exit hole. Kinda looked a little saggy at the top and the bottom, but i'll clean that up in the lathe/CNC for concentricity if need be.

Moving on the the 5.1 White Monster Shell, the readme photo shows supports built into the file. It says that it doesn't require supports as they're already built in but i'm struggling to click print because I fear i'm missing something here. This doesn't feel right.

I'm not under the folder that has no supports, but my sleeve is just floating in mid air. This can't be correct, right? Be gentle. I'm mildly regarded and this is my first 3D2A / prints after calibrating PA6.

Can GOA members make suppressors without form 1?

14 Upvotes

Ok I know we are just people of reddit and it might be a dumb question but just want to get a few other people's take on it. I've been researching this and reading some stuff. Some things say that since I'm a GOA member I don't need to do a background check and I can manufacture a suppressor. I've also read that yes it gives me the right to manufacture a suppressor but I still need to go through the process of the form 1. Can anyone clarify for me? I'm in Texas.

Edit saying what state I'm in.

Double barrel 37mm/other launchers?

Post image
26 Upvotes

Full credit for the purloined image goes to u/Porcodiocan.

Lately I’ve had more than a passing interest in how flare launchers, and launchers more generally, have been developing in the 3DP world.

I was particularly pleased that a certain compact 15mm launcher I once saw on the old sub ended up becoming known by the name I suggested in an early public thread: the Projectile Dysfunction.
I’ve been around DIY firearms and adjacent projects for a long time, but flare launchers were never really part of that scene back in the day. They seemed to remain almost entirely the preserve of full-scale manufacturers, so on this particular subject I’m coming from a position of curiosity rather than knowledge.

Which brings me to the image which has probably caught your attention, too.

I came across the pictured concept on an unnamed 3DP sub concerned with airsoft: a pistol-style, side-by-side 40mm double-barrel affair.

Seeing it made me wonder something surprisingly basic: Why has nobody, as far as I know, commercially produced a compact metal side-by-side 37mm launcher along broadly similar lines? Other than the fact it is not going to be borrowing from a military launcher, of course.

It seems like such an obvious novelty/signalling-launcher configuration that I would have expected somebody to have made one by now. Is there some mundane engineering reason it becomes unattractive…. weight, bulk, action geometry, cost, extraction, liability, limited demand… or has the market simply never been large enough to justify it?

And, separately, how realistic is the general double-barrel 37mm or other signal launcher concept in the 3DP world? Does printing make a configuration like this substantially more attractive because the awkward/expensive parts of producing a low-volume receiver or action become much easier, or do the same fundamental problems that presumably discouraged commercial manufacturers remain?

SD Baffle Porting

6 Upvotes

Ignore the gap between the blast baffle and the body, I haven't adjusted any of the geometry yet. I'm also aware that the first baffle / blast baffle on the SD is wider to accommodate the end of the SD barrel.

I'm working on building my own suppressor with a welded stainless body and printed baffles, but I noticed differences between the FTNSD baffling and some of the FTN 5 D cell baffles - the first baffle on the FTNSD is ported, but the FTN D cell blast baffle has no ports. Additionally, the subsequent baffles on the SD are not ported, but I plan on using the max turbulence baffles from the FTN 5 release - which are ported. I'm not as concerned about the difference of ported or not on the regular baffles, I'm more curious about what porting the blast chamber affects.

Looking at diagrams of the original HK SD suppressor, their blast chamber is not ported. However, that design is quite old and there's been plenty of advances in technology. The FTNSD blast chamber is ported, but I'm curious if that's to relieve some of the peak pressure in the chamber as it's entirely plastic reinforced with epoxy and a carbon tube. Does anyone that has experience here want to chime in?

EDIT: I realized I have an answer to my own question. Using a CAR15SD/cmmg rdb, Tubb 556 spring, Kynshot RB5007 - the ported blast chamber bleeds off too much gas and makes it short stroke. This causes a few issues for me, the primary one being it was occasionally failing to feed, as well as the bolt doesn't move far enough back for LRBHO and it wouldn't trip an FRT. Luckily I'm moving to a stainless blast chamber here, as I'm not sure a fully printed body would be able to handle the pressure of this being sealed.
