Europe is awash in cheap 9mm spitting carbines, and Americans can turn a handgun into a machine gun with a cheap piece of plastic.

In America, a small piece of 3D-printed plastic can turn a semi-automatic handgun into a fully automatic machine gun. In the rest of the world, where guns are harder to get, people are just 3D printing the whole weapon.

Around four years ago a German man named Jacob Duygu designed a semi-automatic carbine with a computer and 3D printed all the pieces. He called it the f*** Gun Control 9, or FGC-9, because he didn’t like Europe’s restrictive gun laws, and the weapon fired 9mm bullets.


Now, Duygu—known online as JStark—is dead, but his weapons are everywhere. According to a new report from The New York Times, authorities have found the FGC-9 “in the hands of paramilitaries in Northern Ireland, rebels in Myanmar and neo-Nazis in Spain.” This was what Duygu would have wanted.

“I have a responsibility to make sure everybody has the option to be able to get a gun,” Duygu told journalist Jake Hanrahan in 2020. “The way they use it is up to them.”

All the pieces is a bit of a stretch. The bolt is a simple weldment, the barrel is an electrochemically machined part
"Jacob Duygu designed a semi-automatic carbine with a computer and 3D printed all the pieces."

How many rounds do the firing pin and barrel last, and is he using PLA, ABS or something else entirely?

Enquiring minds want to know.
 
nope you don`t.
if you wish, there are reddit groups for that, perfectly publicly accessible.

I responded at a similar "level" as the article was written. (I was being snarky) I know the actual FGC-9 would have some metal components as do most if not all "plastic" guns.

There are likely some plastics that could be used in those components, but I have no idea how practical ($$) they are.

Clearly. Because if it was 100% plastic, it would cost more than you make in a month. And I'm not surprised how much you make. ;)

Typically the parts are printed out of Nylon filled with carbon fiber strands. You still need to buy metal parts but they are not regulated so anyone can buy them. Its really interesting how far the community has come along.

You can even rifle a metal tube for a barrel.

Barrel is steel
They have developed a process to electrochemical etch the rifling

Electrochemical etching rifling us OK. At least it is rifling of sorts and better then nothing. Unfortunately it really is not that great and more often then not etches unevenly. What you really end up with is a very inaccurate barrel. However if you are using these
guns as close range pray and spray auto's you have a real useful tool to gun down people.
This type of rifling at this point needs more technical improvement.

Agree that the etching is not a good solution but it is better than smooth bore.

I wonder how hard it would be to put together an electronically controlled pistol length rifling machine.

You could set up a home button rifling set up in your home work shop. You would need button rifling tooling, a piece of i-beam and a good strong powered hydrolic ram. Or you could do broach rifling with the proper broachs and a lathe.
Both types can be done in the home work shop with the proper tools. Button rifling would be the easer way if you don't have a lathe. Check on line for instructions how you can do this.

Imagine the precision required to rifle pistols or rifles 100+ years ago.

It is NOT rocket science, any more than casting boolits. You can do it in your garage with tools from the hardware store downtown.

The concept dates back to Christopher Columbus's day. They didn't HAVE electrochemical etching or lathes with deep bore drilling capabilities. They had damn near little better than flint knives. To hyperbolize slightly...

I was curious so did a bit of research. Sharing if other folks are curious as well.

TL;DR: minus $199 printer, filament and common tools you surely have, roughly $155 and 4-6 days.

The total cost to assemble an FGC-9 Mk II from scratch can vary widely depending on several factors, including where you source your parts, the type of 3D printer and filament you use, the tools you already have, and the quality of the components you purchase. Here’s a breakdown of the estimated costs for each category:

1. 3D Printer and Filament:

• 3D Printer: A basic 3D printer capable of printing parts for the FGC-9 Mk II can cost between $200 to $500. Popular options include the Creality Ender 3 or Prusa Mini.
• Filament: PLA+ or PETG filament is generally recommended. A 1kg spool costs about $20 to $40. You may need 1-2 spools, so approximately $40 to $80 for filament.

2. Metal Components and Parts:

• Barrel Material (Steel Tubing): A length of 9mm barrel blank (seamless steel tubing) may cost around $20 to $50, depending on the supplier and quality.
• Bolt Material (Steel Stock): Steel rods or flat bars for the bolt can cost around $10 to $30.
• Firing Pin Material: A piece of hardened steel rod or drill rod, approximately $5 to $15.
• Recoil Spring Assembly: A suitable recoil spring and guide rod might cost around $10 to $20.
• Steel Rails: Small pieces of steel for guide rails, $5 to $10.

3. Hardware Store Parts:

• Screws, Bolts, Nuts, and Washers: Approximately $10 to $20 total for various sizes.
• Springs: Additional springs (for the magazine catch, etc.) around $5 to $15.
• Drill Rods/Metal Rods: Various small metal parts, $5 to $10.

4. Electrochemical Machining Supplies (for rifling the barrel):

• DC Power Supply: A basic power supply for electrochemical machining can cost around $30 to $60.
• Miscellaneous Supplies: Electrolyte solution, electrodes, wires, etc., around $20 to $40.

5. Magazines and Ammunition:

• Glock-Compatible Magazine: Prices vary, but a basic Glock 17 magazine usually costs around $15 to $30 each.
• 9mm Ammunition: Prices fluctuate, but expect to spend around $20 to $40 for a box of 50 rounds for testing.

6. Optional Tools and Accessories:

• Basic Hand Tools: If you don’t already own basic tools (e.g., files, hacksaw, calipers), these could cost $50 to $100.
• Adhesives and Epoxy: High-strength epoxy and adhesives, approximately $10 to $20.
• Sights, Grips, etc.: Optional accessories can range from $20 to $50.

Estimated Total Cost:

Category Estimated Cost Range
3D Printer and Filament $240 - $580
Metal Components and Parts $55 - $125
Hardware Store Parts $20 - $45
Electrochemical Machining Supplies $50 - $100
Magazines and Ammunition $35 - $70
Optional Tools and Accessories $50 - $100

Total Estimated Cost: $450 - $1,020

————

Excluding the common tools (like files, hacksaws, and calipers), the 3D printer itself, and the filament, the cost to assemble an **FGC-9 Mk II** primarily involves the purchase of metal components, hardware store parts, supplies for electrochemical machining, magazines, and ammunition.

Total Estimated Cost: $155 - $340.

————

The time required to manufacture an FGC-9 Mk II using a recommended 3D printer, such as the Creality Ender 3 or Prusa Mini, involves several steps, including 3D printing the parts, preparing the metal components, assembling the firearm, and rifling the barrel (if you choose to make your own). Here’s a breakdown of the time required for each stage:

1. 3D Printing the Parts:

The FGC-9 Mk II consists of several 3D-printed components, such as the upper and lower receivers, grip, magazine, and various small parts. The print time will vary based on the printer settings (e.g., layer height, infill density) and the speed of your printer.

• Estimated Time for 3D Printing:
• Main Components (Receivers, Grip, Stock, Magazine): 60-100 hours
• Additional Smaller Parts (Sights, Trigger, etc.): 10-20 hours

Total 3D Printing Time: 70-120 hours

Factors affecting print time:

• Layer Height: A smaller layer height (e.g., 0.2mm) provides more detail and strength but increases print time.
• Infill Density: Higher infill density (e.g., 40-50%) increases durability but also increases print time.
• Print Speed: Depending on the printer, print speed settings, and complexity of parts, actual times may vary.

2. Preparing Metal Components:

Preparing the metal parts includes cutting and shaping steel tubing for the barrel, fabricating the bolt, firing pin, and guide rods, and preparing the recoil spring assembly. If you are rifling your own barrel, this step will also include the electrochemical machining process.

• Cutting and Shaping Metal Parts:
• Bolt, Rails, Firing Pin, and Other Metal Parts: 5-10 hours (depending on tools and experience)
• Barrel Rifling (Electrochemical Machining):
• This process can take 5-10 hours depending on the method, power supply, and skill level.

Total Time for Metal Preparation: 10-20 hours

3. Assembly Time:

Assembling the FGC-9 Mk II involves fitting the printed parts with the metal components, installing the springs, assembling the bolt and firing mechanisms, and performing any necessary adjustments or reinforcements.

• Estimated Assembly Time: 5-10 hours

Total Estimated Time for Manufacturing:

Combining all the steps:

Task Estimated Time Range
3D Printing 70-120 hours
Preparing Metal Components 10-20 hours
Assembly 5-10 hours

Total Time Required: 85-150 hours (Approximately 4 to 6 days of continuous work)

Additional Considerations:

• Skill Level: If you have experience with 3D printing, metalworking, and general fabrication, the time could be on the lower end of the range. For beginners, expect to spend more time on each step.
• Calibration and Setup: The time required includes an assumption that the 3D printer is correctly calibrated and in working order. Initial setup, calibration, and troubleshooting of the printer can add several hours, especially for those new to 3D printing.
• Breaks and Downtime: The estimates do not include downtime for cooling, resting, or addressing potential print errors (e.g., failed prints, jams). Expect additional time for any unforeseen issues.

Summary:

To manufacture an FGC-9 Mk II from scratch using a recommended 3D printer, you should plan for 85 to 150 hours (about 4 to 6 days), factoring in all the stages from printing to assembly.

no one needs FGC-9 Mk II in states and no one makes it.
europeans who cannot easily buy slides and barrels are in the different realm, so, down there, yes, they have to go through more obstacles where money are no longer a factor, as it does not matter how much it costs if you are forbidden to have it.

pla+ i buy in bulk, usually at $11 per kg. cheapest nylon now is at $19 per kg.
modern good xy printer costs $500+ - creality k1 / k1max. but it gets cheaper constantly, as this field evolves quick.

i do not print guns and have no interest of doing, as it is a street gangbangers realm. to each their own, FAFO.
but, it is for sure out there and is as massive now as it gets, and, well, the jinnee is out of the bottle.

Yeah I think the author’s intention (rest his soul), was that if you need a gun but haven’t been able to secure one, you can make one that doesnt involve a shovel handle and have a chance to survive.

As far as I know possession of plans, printer, filaments and a few metal parts aren’t illegal, even in MA, so it might just not be a bad idea to pick up the stuff needed. Just in case things get really really bad.

The primary person running for President is on video saying she would absolutely implement a national forced gun confiscation “buy back” program. She could be sitting in the Oval Office in 128 days.
 
if you need a gun but haven’t been able to secure one
yes it is incredibly simple to produce now.
4-5hrs for a glock. 8-9hrs for ar15 lower.

in order to stop that they would have to turn everything upside down, make usa into europe, start serializing slides and barrels and, preferrably, install a king of america.
 
Just learning about this guy…listening to him, you’d think he was quoting the Founding Fathers.

Jacob Duygu, known as “JStark1809,” died in October 2021 shortly after his home was raided by German police. Officially, his cause of death was reported as a heart attack. However, this has sparked numerous conspiracy theories within the 3D-printed gun community. Some speculate he was murdered by authorities.

He died 11 months after this documentary on him went up online. Worth a watch.
