Looks good! Are you going to put like a tripod to make it look like an M2 or something? That would make it ven more amazing! Is it very powerfull? I would have thought with that 10 ounce tank. You must need a lot of butane to power it, does the small piezo work in something that big very well?

yeah, the piezo works amazingly, it gives me a spark about a half inch. It is smaller than the other piezos I have but seems more powerful. It uses about 5 seconds worth of butane. I havent been able to test it yet cause Ive been running around all over the place today so I have no Idea how much power it has. when i screw the barrel off and fill it up and click, it makes a huge flame and whistles. I am going to get some more caps to screw on the mouth of the tank so I can have more barrels.
I was hoping to make this the pneumatic, but the schraeder valve wouldnt stay in, the epoxy wouldnt hold, so I just stuck the lighter nozzle in the hole and it was a tighter fit, I will put some epoxy around this to make sure that it stays in
Ill let you know once i test it for how much power.
and by the way, I couldnt view your PM again Urban Ninja

Edit: about the tripod, I might do it, or something else, all depends on if I stop being lazy, and what I can find around the house. I have to find something to sleeve my barrel in also because it is bent
Im also going to make a combustion gun out of a travel size mouthwash bottle and a small tube that I dont even think a BB will fit in, just for $H1ts and giggles, Ill probably use needles in this

Yeah needles with a ting toilet paper tail. Ill send you an email with it in. For the bipod I just get 2 kebab skewers and tape them about an inch and a half together at the top. works for me if im too sleepy or lazy to make a metal one. I have found that a lot of my mini barrels are bent. Thats the only thing with them. Fiddly bas#*@s.
