It will make it more powerfull too!

so a for every 7" of the chamber add a 1' to the barrel.

go to a hardware store and get some plastic tubing to go around it and put a on/off valve in the middle or at the end of the tube. Just a though, not to sure if it will work.

I used ABS....and i am adding a BBQ igniter into it.... But the ingtinter will be out only the spark will be in. So no starting fluid?

What i the best stuff to use to ignite?? Aqua Net?
