The Ark @fosscad.io So uh... What's the most powerful cartridge we've managed with direct blowback?

The scrap pile provides once more! A single cut was already made, like it was meant to be.
Staacker, Nameless, and cat for scale.
Safety and practically issues aside, I want to know how much pressure can be wrangled, without having to actually do any work making a locking bolt. I know jack-shit about ammo, so feel free to point me in the wrong direction if you'd like. I fully expect this to end badly, but it's not like I'm going to do anything productive if I'm not trying this, lmao.
Again, practicality is out the window; it can be obscenely heavy. Closed bolt because it's scary enough already. AR-15 fcg almost certainly because I'm poor and I can print one.
Alternatively, a fence-post 37mm barrel is a pretty great size for a simple, square barrel sleeve. How feasible is a blowback 37mm? I remember PY2A

The Ark @fosscad.io Would it be wrong of me?

So i get a lot of questions in my inbox regarding one the archive I established for the back up of the conglomerate of files I have. Two how to set up P.I.D. controllers due to my background in Engineering and Maintenance. Three my file and or slice settings for the prints that I post. Today whilst conversation with the wife, and browsing the interwebs for E.D.C. prints, my wife popped off with the wonderful thought of posting the files I have as "reference models", to Cults and other places and as im most of the time downloading new releases and testing the prints for best orientation / readme edits to the slicer. As for possibility of donations on the files I release for further R&D, development of dryers, time spent archiving, more filament, etc.. As I would give credit where it's due and not claim ownership of the

I know not the normal topic and I want to stay out of politics on this sub, but I thought it should be mentioned... especially for those of us who want to see some changes in the NFA... especially around hearing protection and fun buttons. If the mods feel this is too off topic, please remove and I apologize.

The Ark @fosscad.io Hammer follow with the armp5 lower
Originally posted by u/EdgeofthePage at 2025-06-27T22:27:09Z
I have a printed armp5(v1 - so maybe I should reprint...) that is getting hammer follow. The ha.mer drops fine, it fires, cycles, ejects, but the hammer either follows the bolt home(does not go off) or stays back until I let go of the trigger. But instead of resetting, it drops the hammer. Almost like being in binary mode 😆
Anyone seen this? Thoughts on what I might do to resolve it? Thanks
