Legit full auto rather than a constant airflow with a tube stuck in the middle of a container full of BBs.
Thanks! The quest for efficiency compared to vortex/cloud BBMGs never really went away

I was really surprised when I saw that thing clacking away. That shit was impressive. I've never seen an airgun work like that before.

You cannot see the blueprints for this weapon in the directions in the first message. Do you have them, Jack, so you can see them? Or else, do you know where they are on the web?

I tried building a similar blowback gun, running at 200psi with green gas. Even with a port to the hammer tube, so having the air push on the bolt and the hammer, it still isnt strong enough to make the gun run automatically.
I might shelf this project and go back to semi auto stuff

Your hammer spring must be too strong, the reason I used a balanced valve in this project is to make sure I could get away with a relatively weak spring.

Interesting find! Since this involves high-pressure air/CO2 and machining specs, just a friendly reminder for anyone attempting this: please check your local laws—some jurisdictions regulate airgun energy limits and full-auto mechanisms.
