that's nice .. i like all the pictures and your mods and stuff

try wrapping paper around it .. in a cylinder way...

do some research and know what you're doing so you don't blow anything off...

how far can it shoot .. .that thing looks inmpressive

that's huge ... like a freaking basooka or something ...
