Very cool! It stinks that you can only dry fire it, though. What kind of psi are you planning on going up to?

not matty there is only 1 female bushing and 1 male,
its like that to service the piston, then the pilot screws into the back of the one bushing
is was at only 20 psi, but my camera audio sucks
I can only dry fire it, but have shooten potatos at plywood and they go right through,
thanks matty and other dude, matty i cant wait to get my other cannon going(unison minds)
i plan on running it 60-100

but when i moved cops are DICKS and i already have to pay a fine from something else, dont want anymore problems!!!

The cops in my area are okay with pneumatics... but not combustions.
I guess to many stupid kids have hurt themselves and others with fragmenting PVC.
Gotta wonder what they would think of my hybrid....
I live in a pretty rural area, where the sound of shotguns can be heard almost every day.... so no one minds my relatively quite air cannons.
There was one time though.... when i shot my 1.9'' porting piston with its 1000 cubic inch chamber at 250 psi... the neighbor almost a 1/4 away, was heard yelling "what the F**K waht THAT?!?!?!?!"
It kind sounds like a bomb going off.
