maybe not fully gun related but i'm working on a bullpup airsoft gun (RPKs) and was wondering how to link the real trigger to the bullpupized one

Hey I have a Creality CR5 Pro was wondering if this a good printer wanted to get into printer lowers …. Not a narc ….. what’s some good material and stuff I should know

Hello friends. Has anyone tried to convert PAK to fire version ? I assume change 7,65 barrel, the cartridge fits very well in the chamber. Any ideas or advice ? I haven't found much about this conversion anywhere.

PS: I'd be a bit afraid of a stronger caliber, as it doesn't have a very strong shank. I've also been looking at reworking the Reck Commander to 6.35

I just turned 18 and have no idea what I’m doing will people please either help me out on here or privately msg me? I am very interested in this and hope to become a machinist in the Marines.

So how do i do this myself? Just throw me a list of things I'll need to do and I'll get started.... thanks ya'll

I have some questions about 3D guns. I don't have any knowledge about the subject other than watching a few videos on YouTube. I'm in the early stages of this subject, so my questions may sound ignorant. That's why the information you provide is very valuable to me. I wanted to do some research but I didn't know exactly where to start. I would appreciate it if you could guide me.

1. Are all parts of 3D guns made with 3D printers? Or are there stages where we need to use CNC? I'm especially confused about the firing mechanism. Does the polymer provide sufficient durability during firing?

2. Can you recommend a content or site where I can get at least introductory level information about 3D guns?

3. I looked at the printer used by the channel owner on the PSR Youtube channel. It had an average price. Can a 3D gun be made with an average 3D printer? What are the features the printer should have?

4. Can the same filament be used in every gun? Or do filaments vary from model to model?

Thank you in advance.

Any firearm designers?

I’m looking to bring a product to the Canadian market but I don’t have the skills to code or design I only have the idea and the money to pay someone else to help bring my product to life so if any gun designers are looking to make some money get in contact with me if you’re Canadian that would be a plus.

A cool part I made wanted to see what people think. Machining Tommarow

Point to oddball pipe sizes which aren't Google-able because either the info is out dated or half assed metric to fractional conversions.

Thought I'd ask here as I'm having zero luck. I was looking for a .410/45LC tubing option and can't find a clear answer. Something say a 3/8ID pipe would work, but that cannot be optimal?

Howdy all Iv been trying to find a definitive answer on this with no luck. Does the VMAC kit work with original Mac/cobray uppers or is it a proprietary system that needs their brand upper?

Reaching out to see if anyone has a 3d file for a Walther P99 rear grip?

Many people thought that with 3d printed technology, anyone would be able to print their guns at home and bypass laws that prohibit our right to self-defense.

Of course, fully plastic guns were initially limited in durability, with early designs lasting only a few shots. There are now plastic versions reinforced with metal that last longer, but inevitably, certain parts must be made of metal for the gun to function reliably over time. Also, homemade guns are nothing new, people have been building them for as long as firearms have existed.

Owning a gun is meaningless if you don’t have access to ammunition. While it’s possible to 3D print guns, you cannot print ammunition.

In countries where guns are legal, obtaining ammunition for a homemade firearm is relatively easy. You can either purchase ready-made ammo or get the necessary components, like cases and primers, to reload your own.

In countries with strict gun control, only the government and criminal organizations like drug cartels have easy access to firearms and ammo, as they have the means to smuggle them in.

Producing ammo components at home is extremely difficult and impractical. Manufacturing ammunition is only feasible in factories, which are easily targeted or controlled by the government.

Before the adoption of brass casings for ammunition, guns were more accessible, and people had an easier time keeping governments in check. I’m not sure if the transition to cartridge-based ammo was done intentionally to regulate gun access or simply because it’s more efficient. Either way, the shift has contributed to greater restrictions.

Weapons design has stagnated since the end of World War II, with no big innovation, Innovative weapons like the G11, HK XM25, were introduced but never fully developed or widely adopted. And more recently, the RM277 with plastic ammunition.

Why there is almost no innovation in gun design, is because the biggest buyer, the governments, is too conservative to accept change?

I want to propose a future weapon, a true liberation weapon that doesn’t require industrialized ammunition.

The first challenge: the primer.

To ignite the gunpowder, we need an alternative to conventional primers. While electricity can be used to ignite powder, it’s not as straightforward as it sounds. Standard electric lighters or spark plugs are not sufficient to ignite gunpowder. After researching and help from the community, I found two existing solutions to this problem:

1. CVA Electra: This system uses a circuit to generate plasma capable of igniting the powder. However, it requires a larger battery and a more complex circuit to function.

2. Remington EtronX: The EtronX is an electrically primed ammunition system. It heats a wire in the cartridge to ignite the powder, though the need for each cartridge to contain a wire coil adds complexity to ammunition production.

The second challenge: the casing.

There are four potential methods that eliminate the need for a traditional metal-formed casing:

1. Assembling ammo on the go: This idea requires advanced mechanisms and precision in timing, measurement, and sealing, making it overly complex for practical use. Modern technology allows for greater accuracy in handling loose powder and projectiles, potentially making this a viable option for future firearms.

2. Solid ammunition (G11): The G11's caseless ammunition was ahead of its time, with the propellant bound to the projectile. Though manufacturing and safety concerns hindered its adoption in the past, improved materials science and more precise manufacturing techniques could reduce the risk of premature ignition.

3. Paper cartridges: Paper cartridges were used before brass casings became standard. This method requires lubrication for smooth chamber insertion and is prone to tearing, which could lead to reliability issues in the field.

4. Plastic casings: Have excellent heat dissipation, plastic casings are likely the most efficient option. However, they require a complex plastic casting process for mass production.

To be a truly accessible firearm, it must be simple and easy to manufacture. The best combination for this purpose would be the EtronX system paired with paper cartridges.

For the gun's construction, both the barrel and bolt need to be made of metal, as I don’t believe that a plastic barrel reinforced with a metal pipe would have sufficient durability over time. The metal components should be designed to be easily machined using a lathe or other basic methods, my knowledge in this area is limited.

The remaining parts of the gun can be 3D printed, and customizable.

Multiple versions could be developed, ranging from the simplest designs to more complex:

1. A simple bolt-action, single-shot firearm based on the Chassepot 1866 design.

2. A semi-automatic revolver, similar to the Webley-Fosbery design.

3. A magazine-fed, semi-automatic firearm with a reinforced barrel to withstand heat without the heat dissipation of the cartridge.

4. A magazine-fed, fully automatic firearm with a slow rate of fire to mitigate heat buildup.

5. A magazine-fed, fully automatic firearm with a revolving cylinder mechanism to manage heat buildup more effectively.

Paper cartridges can be reloaded using a 3D-printed reloading press. Requiring only a thin wire coil. The projectiles can be as simple as ball bearings or custom-made using a lathe. Black powder is easily produced with just a few basic ingredients.

A commercial version could be developed based on the RM277 design or something even more advanced.

Nothing suggested here is new, everything has been proven and works. It simply needs to be combined and released as a free, open-source design, with the potential for widespread adoption.

A Gatling gun that only need black powder and ball bearings would be extremely cheap and fun to shoot.

Let me briefly explain why access to guns is essential. If you're already familiar with this argument, feel free to skip ahead.

Guns are the most effective means of self-defense available today. They give individuals the ability to protect themselves and their loved ones, as well as the means to resist authoritarian governments.

Gun control laws don’t stop criminals—they ignore the law by definition. Instead, these laws prohibit law-abiding citizens from defending themselves. The foundation of America was built on the right to bear arms, a testament to their importance in securing freedom.

In countries like Venezuela, North Korea, and Cuba, if citizens had access to detailed plans for making a weapon like this, they could fight back against the authoritarian regimes that not only destroyed lives and freedoms but also killed countless people.

I currently lack the necessary resources to fully develop this project. I am trying, but with what is available it will take a long time. If anyone has the resources and would be willing to develop this project for free public use. I truly believe it has the potential to change the world.

Additionally, if anyone is able to share this message, improve upon it, or present it in other formats such as video, your help would be greatly appreciated.

Hello. Would anyone be able to tell me what rifle these lower receivers are for? Thank you!

Where’s all the videos and DIY on setting up something “safe to shoot into that muffles the sound” in your house to test pistoles and rifles. The bucket tricks cool but I’d like to upgrade to something much more efficient and safer. Is there such a thing to make or create nowadays?!

Without linking or breaking rules, I just want/need to know if they exist as 1's and 0's "out there" so I know I'm not hunting for a jackelope.

Hard to even find pictures of the cut pieces to extrapolate a pattern from.
