The barrel is 1/4OD copper, and I usually shoot BBs out of it. To keep the BBs from rolling down, I glued a single strand of wire over the end. The ignition is a peizo grill ignitor since I had a few lying around. That provides dual sparks using 4 little screw in eyelets. The fuel is butane, since it is the best fuel in my opinion.

Nice pill gun makes sure that the barrel is secure. I had a bad experence when my pill gun launched its own barrel.

all though i admire your creativity to make a dual spark , it really isnt nescisary(excuse my spelling) for such a small chamber. oh and are you going to make it look a little nicer because it looks sloppy (no offense). good job anyway what do you shoot the bb's at? your cat lol just kiddin, but really

The duct tape is to hold the electrodes the right distance apart (not sure if I mentioned that). I plan to hot glue them or something, I'm just lazy.
The barrel is attatched pretty well. It's got a good amount of glue on both sides.
I usually shoot the mini at my jacket I have hanging up, it's right across my room from my computer desk, which is where I usually am. The jacket doesn't fit, I just have it up to use as a target.
