This is the second gun i have ever made, it has a 4" combustion, 3" corner, and a 2" barrel but i left it threaded so i can change it later if i want, i used a 1 1/2 ball valve and i kept the chamder detachable incase something happens to the fan. metered propane but i left the pipe a little long for it just to lazy to cut it, i just have to clean it up a bit and move the wiring around, other than that any tips or questions?

yeah i am going to be adding a longer barrel soon, i have tried it a couple times and it shot not bad but here the tempurature is about -10C and the tank preasure dropped to about 55, were it should sit at about 95, any ideas for a better sparker, tazers are illegal in canada and the ignition box on bc arms is a bit to expensive for me

I'm just down the hill from the hospital. I usually go out either behind the slimes or to Hershey lake to shoot my spudguns, depending on how many people are around.
