I have not had 1 for awhile.It was just a basic straight,potato gun with BBBQ igniter.But if you want to have some fun build a mini one.I took a electronic lighter,a medicine bottle and a aluminum arrow shaft ,to make a mini potato gun.It worked really good.Just slice your potato about 1/4 in thick and use your barrel like a cookie cutter.It would easily fire them over 100ft,but they caused no destruction.Even when fired at indoor targets.
