Secifications:
Piston: hot glue, rubber washer, and a bike innertube on top

Chamber: About 40cm of 22mm copper pipe
Barrel: 70cm of 10mm alluminuim tubing
fill valve: Good old schrader

Pilot: blowgun (but im thinking of putting a pushbutton valve on it)
Thats it


The gun itself without the stock (and some toes)

Thats not the actual piston but it looks a bit like it.

With the stock on.

And theres the half done 22mm tee piston
