the acronym stands for Semi Auto Fire Extinguisher, thought it was kind of ironic. it has the same method of a semi auto i used on my other bb semi. it also can be used without the mechanism to make it full auto/burst fire, i'll try to find the picture of the mechanism

The full gun

The machine screw had to be put there because there was a pressure relief hole there, which would leak otherwise

The modified brass bushing i had to use because the siphon tube which was originally there snapped by just touching it, i needed a way to keep the trigger spring in place, so i turned it down till it would fit.

is this like the other gun you made that had the piston, that semi auto gun, or does it not have the piston so it can fire full auto? anyway, how many shots can it get off?

i'm not sure on the volume, its fairly small, good for a shoulder fired cannon, the valve is the one that was on it, it uses a pin with a sealed end which is pushed down into a larger opening where the air can get past it
