Looks reasonably solid. Doesn't that pressure gage need to be on the handle side of the trigger? ...rather than the exhaust side?

Nope, ain't a semi. It's a multi shot cannon but you need to load and pressurise it every shot, semi-autos load and pressurise themselves after firing.

Looks nice and light, good for plinking :)

That's pretty sweet. It's small, compact, and looks pretty effective.

I would remove the gauge, it's useless and distracting in its current location.

Nope, ain't a semi


A blowgun as a main valve gives you the luxury of multiple shots per tank so all he needs is a magazine-

I'm not disagreeing with several shots, but I believe the multiple shot factor is more from opening and closing the ball valve behind the blowgun and after the not-yet-installed main chamber rather than due to limited flow from the blowgun.


Oh yes I only just noticed, the gauge is measuring the pressure of the barrel
:wink:

A semi-automatic weapon is semi automatic because it automatically reloads a new round and neccecairy source of propulsion.
This gun is replacing its propulsion source in a quick way though it is still done manually, and loading the ammo is still the same old way.
So both the propulsion as the ammo are not loaded semi automatically.

You can tell how awesome a cannon is by the pressure used.

What the heck do you mean with that?!
Unless the projectile jams, the pressure will be atmospheric after the shot.

If you mean chamber, instead of barrel, it is also atmospheric. He refills the chamber every shot by opening and closing the ball valve on the back.
