    Identity concealment through language scrambling

    There are many aspects of operational security (opsec) to be mindful of when posting in online communities or revealing any part of your identity. In this community, there is an immediate need for good operational security, and those who aren't careful enough will face the consequences of their mistakes.

    There are obvious points to secure, such as not linking real identities to those in this space, but one of the most overlooked issues is a form of fingerprinting through matching vocabulary.

    Each person has unique language styles, and this becomes more apparent the more they write. If you only write short sentences or keep discussions brief, it's harder to match your language patterns with another identity, as there are fewer chances for unique linguistic patterns to emerge. However, if you contribute extensively to this space (and such individuals are often targeted using this approach), you are likely to write large amounts of text, such as in forums or PDFs. This can provide ample

    Securing Mobile Platforms

    Never buy “ready private phones” or devices with preinstalled “privacy” software. If you want a phone with strong privacy protections, install GrapheneOS on a Google Pixel.

    Most phone operating systems on standard hardware (stock Android, iOS) are vulnerable to tools like Cellebrite and other forensic/remote attacks. GrapheneOS is significantly more secure.

    Many mobile apps depend on Google Play Services, which includes features that undermine privacy. microG is an open-source reimplementation that lets some apps run on a de‑googled device, but it is not compatible with all apps.

    Using two devices is recommended: one for everyday activities (social accounts, general browsing) and a second, locked‑down device for sensitive tasks. Some apps collect extensive logs and metadata even when they claim to be private.

    Strong end‑to‑end encrypted messaging apps to consider:

    • SimpleX (strong privacy features)
    • Session Messenger

    New community for stealth discussion

    The new community (c/stealth) is made for being stealthy on all fronts, including evading persecuting forces in real life and in the digital. This encompasses tactical measures for evasion of surveillance and measures which decrease profiling risks on the internet. If you are interested feel free to join.

  • It does seem like an interesting route. Only thing is that it seems like it would put a lot more force on the receiver from the accelerator lever so a metal element would probably have to be inserted in the section of contact. I think my concern with that is that it would put a lot of stress on a polymer receiver, yes there are examples of higher caliber weapons in production with a blowback system but if the receiver is less strong then it could put too much stress on weaker components and it could be a safety concern. I'm still learning but this is my view right now.

    By higher caliber I mean higher than current hybrids (9mm) so 5.56/300blk and 7.62x51.

  • Trying to think of a simpler mechanism than rotating bolt lugs. The lugs on a typical assembly could be made from a steel part with a rim on one side and filed down using a guide and then drilled through the middle for the firing pin. The main issue I think is the complexity of the bolt internals. It may be possible to FDM some of the internals that don't take the brunt of the stress (maybe in a CF polymer) though again it may just explode.

    If not using direct impingement the bolt can be simpler however it would still take many drill guides. The extractor and the breech face lock itself seem difficult to make unless they are changed.

    I suppose if a barrel with taper could be successfully made with ECM then the breech face could be as well with the same principles? Maybe with 6 wires just inserted into the end so that it creates the pieces to lock into. I definitely need to do lots of experimentation so see if all of these ideas are possible.

  • I think a blowback can't really be done at higher calibers without too much internal stress for these calibers. I think right now making a DIY gas system isn't the priority, first is making a working bolt-action higher-caliber as it would still require a lot of development.

  • I think expectations need to be maintained when making higher caliber weapons. I think what would count as "DIY'able" to me is for the gun to be made in Europe with no special equipment or custom parts, only with FDM, standard tools and common metal parts (except the barrel). Without welding is ideal but not necessarily a requirement.

    Delayed blowback does not really solve the problem because it wouldn't work for stronger rounds (or it would likely be unsafe). For a piston system (for example) a steel block could be used, then one hole drilled that connects to the gas port hole and then one larger drilled hole containing the hammer system. The hammer used could be a common metal part that simply fits the diameter of the drilled section.

  • I think making the DIY barrel should be the first priority. For the chamber a usual method of ECM can't be used so my idea is to use a linear motor that travels along the taper with precise timing to remove more material at the start and less at the end to create a smooth ramp. This paired with a copper ring that would selectively reduce one small section at a time. A lot of these DIY processes for ECM seem to have too many variables for failure, in my opinion it is more ideal to have a standardized system for ECM to prevent outside variables impeding accuracy. This can be done by printing everything (even the container) and making the motor/ECM process itself controlled with a microcontroller.

    Just to note I'm not sure if this idea for ECM is even physically possible as I'm not experienced with it.

    Hybrid High Caliber Weapons

    I'm interested in helping research towards making higher-caliber weapons possible with fully DIY components. I'm still not that well versed in weapon design and I know many people here have more experience with converting components so the main thing I'd like to know is what limitations need to be overcome?

    I have an idea for the ECM taper that may work but it's yet to be tested. The other complexity is the bolt carrier group and the locking mechanism but I think that can be made with guides. The other consideration is the gas system, a section could be attached to the gas port without welding with a clamp but then I'm not sure if direct impingement or a piston system is the way to go.

    Any help is appreciated.
