An airblaster of the shittiest design, this is as janky as it gets.
Sprinkler valve, AS-20 pump, 36" copper and cpvc barrel, and 300 fps with a 20 second reload time. Immensely accurate, sacrificing everything to hit a dinner plate at 35 yards.
Potato cam, sorry.
Takes 10 pumps to reload, tank is 3" of 1" galvo pipe. Firing pressure is 60 psi, on the dot. Too high and it loses accuracy. First 8 inches of barrel are .495 ID, remaining 28 inches are 9/16 ID.
As I said, as janky as it gets.
