not my design. Has anyone seen/done anything like this before? could it be converted to semi?

I made it, but couldn't get it to cycle properly at a good speed. (not the original, I made a replica). I have no doubt that if you were prepared to spend time working on it, you could get it going fine.

I wouldn't bother spending the time getting that auto and then making it into a semi. There's cheaper and more powerful options.

if you want semi then there are far far easier and more flexible options, like a trigger operated hammer valve, or a qev plus a 3 way valve.

I'm planning a basic piston cannon atm, after that a hammer, similar to sniper hero's (based on a diagram by btb), hopefully semi, provided I can balance the forces correctly. I was just curious about this approach to a full auto setup. thanks for your replies.
