Hello all, and welcome to the official GunCAD Index Forums, a place for anyone to discuss DIY gun content and all things adjacent. Browse around, everything should feel pretty familiar.
If you haven’t yet, hit “Sign Up” in the top-right corner to make an account and get to posting. You can make posts in existing communities or create whole new ones if you want your own space.
If you’d rather browse, either scroll through the feed on the main page by hitting the logo in the navbar or hit “Communities” and browse for a subreddit community that seems interesting. Play with the selectors and sort options, too.
A Note on Reddit's Rule Changes
/r/FOSSCAD was banned a while ago, but starting October 9th, Reddit is adjusting its rules such that the following are now verboten:
-
User-to-user and user-to-vendor transactions of firearms and accessories (including things like magazines) where one of them is not a “licensed vendor”. This completely destroys /r/GAFS and blows away all Super Safety advertising, too – check out !supersafety@fosscad.io
-
Any directions on how to make a firearm, including 3D-printable design files and where to get them. This will absolutely be used to shut down even the thinly-veiled “Odd Sea” posting, which turns all of the 3D-printed gun sub hydra heads into glorified build showcases, if they’re not getting banned outright.
The site is now actively, outwardly, and aggressively hostile to gun content more than they’ve ever been.
Comparison of Lemmy to Reddit
The site runs on a piece of software that’s adjacent to reddit, but comes with a few key differences. The flow of upvoting/downvoting/crossposting content onto subreddits communities should come intuitively, but:
-
There’s a big
@forum.guncadindex.comat the end of several URLs and embedded in several places on your UI. It’s just like when you see:matrix.orgwhen you’re on Matrix, don’t worry that much about it -
Data is controlled by me, The Shittinator. And seeing as how I run the GunCAD Index, I don’t have any issues with directly linking to content or discussing the nitty gritty of designing and building firearms. There are still some restrictions though, just to keep everyone out of hot water – see the sidebar
FAQ
Most of the FAQ exists in the site’s global sidebar, but here are some extra ones:
Q: Can it look more like a site I’m familiar with?
A: https://forum.guncadindex.com/
Q: This site looks like dogass. Is there a better frontend?
A: https://p.forum.guncadindex.com/
Q: What kind of data do you collect?
A: As part of signing up, you’re trusting me to store your username, hashed password, email address, and all your posts. It’s either that or I manually approve every signup. Use a burner if you want, or you could spin up your own Lemmy instance and federate with us. That’s fine too.
Support Us
This site stays up via funds from the GunCAD Index’s sponsors and your individual contributions. If you can, please consider supporting us:


So if all our data is currently on your Lemmy instance, is it possible to migrate accounts to another Lemmy Instance? Like the reverse of an existing Lemmy account or instance federating and interacting on this forum. And in the event where the host of your Lemmy instance is taken down, would it still be possible to migrate to another instance?
There’s not an automated way to do that, but you can export all your settings – your name, PFP, subscriptions, etc. – to a file on your computer via your profile settings, make an account on another instance, and import those settings. You would need export ahead of time.
For resiliency: if this instance goes down, it does not delete the federated activities from other instances. So other instances that federate with us like fosscad.io will retain all of our posts unless they elect to remove them for whatever reason. Images are liable to be lost unless an administrator specifically configures the picture hosting submodule in a way that caches our images.
Thats great to know, thanks.
