Awesome how-to video! I'm working on a semi-auto with same reloading mechanism, but I intend to use cartridges instead. And I'm so jealous of your valves. You just clean your room and you happen to find a couple valves laying around. :lol: can't wait to see what you turn this into!

If I get any time, I´d make this in to a M82 look like .50cal rifle.

lol, that is some basic pneumatics... a single one is much easyer because it has only one pilot side, the oter is exaust (waste air from the piston) also you need a les complicated (3/2 ventil (dont know te right word)), a double action piston needs a 5/2 ventil

this is in normal pneumatic diagrams not spudguns xD

You mean 3/2 valves...
Now stop confuse people, it´s not necessary to use a 5/2 valve to use a double acting pneumatic cylinder. I used a double acting with a 3/2 valve.

So I made a simple .50 cal semi-automatic using 1/2 inch stainless steel tube as the barrel. It works like the most basic 3-way+QEV+pneumatic cylinder semi-autos, the cylinder it´s connected to the chamber of the QEV and it´s used for reload.
Any question just ask POLAND_SPUD :D

Check out the "how to make a semi-automatic airgun for beginners" thread (I'm on my phone so I can't link it, it's in the how to data base as well). But basically you just need to use a smaller 3-way and cylinder (probably order a custom one).

Simple just use higher pressure. Kind loud when fire it with 20 bar or higher

Semi auto, power, ergonomics, all in one. Clearly something built by wyz2285 :D
