You might want to switch to rootless quadlets with subuids

You’ll get unified logging through systemctl and journalctl, you’ll also get segmented user space and if you need persistent storage that you can gate at subuid.

I was worried about the two rods running as dipole interference but I guess I was being over cautious

I’m just a lowly embedded engineer working on BLE on aarch and other SOC kernels.

I would suggest carbon fiber rods or aluminum, ferris metal could interfere with the bluetooth radio depending on their shape.

Openbao -> keycloak with a TOTP on new devices

This seems like a fishing expedition post.

BRN-10, Jackyl, CMMG Dissent all rely on a buffer tube ring and will crack the back of a printed AR lower.

This will happily cycle an AR 10 upper with a buffer tube.

You have a good idea about reinforcement. Screw the endstop block into a blind hole in the back and have a monolithic lower with stock. Like a short stroke WWSD rifle.

The bufferless part is a bit of a sticky widget as the back of the reciever usually stops the rearward travel of the BCG. So actually buffer tubes being made from steel and allowing for slower deceleration of the BCG make for a better candidate for “softer” lowers.

If there is buffer less upper that doesn’t use the lower receiver as the backstop for the BCG please let me know. I stopped following shotshow a decade ago.
