  • the kinetic energy of pip9 nearly a 22lr and 9mm deep's kinetic energy not higher than a 380acp i think it can change to adapt the design,I heard there is an ammo 9.2x19mm --To save on costs, some American reloaders create "wildcat" cartridges by seating Makarov bullets into 9x19mm casings; however, this necessitates a modification to the firearm's chamber design.

  • Do they typically use standard, purpose-built airgun valve components?Because i am in China buy airgun value will face risks, it's very difficult for me to source specific airgun parts where I am. I was wondering if it's feasible to substitute them with standard, unregulated pneumatic valves (like generic off-the-shelf commercial valves)?

  • Hi there, your 3D-printed airgun design is really impressive! I saw that it can handle pressures up to 1000 psi, and I'm very curious about the engineering behind it.

    Could you share some details on the following?

    1. How exactly is the mechanism implemented? > 2. Which specific parts of the airgun are 3D printed?
    2. How does the design withstand 1000 psi? Are there specific filaments, print orientations, or reinforcements you used to prevent failure under such high pressure?

    Why is there a lack of 3D-printed airgun (PCP/CO2) projects compared to firearms?

    We've all seen the massive explosion in 3D-printed firearm development recently. Designs like the FGC-9 and Urutau are incredible feats of engineering. But this got me thinking: why don't we see the same level of innovation and high-quality projects for 3D-printed airguns?

    Logically, it seems like airguns would be a much easier and more accessible path. Components like constant pressure valves, regulators, CO2 cartridges, and HPA (High-Pressure Air) tanks face far less regulation globally compared to live ammunition, primers, and barrels.

    Given the current capabilities of 3D printing, shouldn't designing and building reliable CO2 or PCP platforms be easier? Is the core issue engineering-related (e.g., containing sustained high pressure in printed plastics vs. the momentary peak pressure of a 9mm cartridge)?

  • Can the SR722 be modded to shoot heavier rounds

    Jump

  • because it need ar15 barrel and bolt head,it is hard to get out of USA

  • are you in china? In china only 6.8 and 6mm nailgun ammo can get, s5 nailgun ammo-.22is nearly impossible

  • well Stubb K98 is very hard because it need ar15 parts, it nearly impossible for me to get ar15 parts

    Can the SR722 be modded to shoot heavier rounds

    Is it possible to modify the design of the SR722 to fire more powerful ammunition, such as 7.62x39, 7.62x51, or 5.8x42or43R

  • How do we feel about PETG-GF?

    Jump

  • For a long time, many people（such as reddit） have believed that PETG should absolutely never be used in 3D printed firearms. Is this reasonable and scientific? Furthermore, with recent improvements in PETG materials and the advancement of 3D printers, has PETG become a viable option worth trying?

  • Do you have more technical details on the modified FGC-9 that runs '9mm deep'? I'm curious about the bolt weight adjustments and the recoil spring tension needed to get it to cycle reliably. Any documentation or links would be much appreciated.

  • What caused the .380 ACP printed ammo project to be pushed aside for now? Was it a technical hurdle or just a shift in priority?I actually have an idea I'd like to explore: using a 9x19mm profile for a 3D-printed casing, but down-loading the pressure and power to .380 ACP levels. The goal would be to make it safely cycle and operate within an FGC-9 platform without overstressing the printed case. I’d love to hear your thoughts on the feasibility of this for the BLC project.

    Current status of 3D printed ammo development

    Does anyone know the current state of 3D printed ammunition research? Specifically looking for info on the BLC tests and 3dprinted .380 ACP projects（case also 3dprinted）. Since a lot of the usual Discord/FOSSCAD channels are down, I’m trying to find where the community is currently documenting these developments.
