WORKING Simple Semi auto mechanism

This is a simple pneumatic mechanism I made. Just uses a 3 way roller mechanical valve and a QEV. I need ideas on a working bolt so if you have any plz lmk.

I built it into my single shot airsoft

Made the piston from a 6mm bolt and a piece of nylon

The blow forward bolt definitely works and is relatively easy to build:



What projectiles are you looking to fire though?

i was thinking paintballs or rubber paintballs

For rubber balls a simple breech like farcticox1 made here would do the trick, paintballs would get smashed though.
