its a 2inch pipe that goes into a 1 inch the two inch pipe is 16 inches long and th 1 inch barrel is 26 inches long i guess it fires ok but the first pneumatic gun i made was 100 times better it would fire a paint ball out of sight

You should take apart that lighter and use the sparker, it'll work much better.
