This is one of my first combustion cannons. It features a 4" SCH 40 chamber @ 18.5" long with a 3" SCH 40 barrel @ 36.5" long. It also has direct propane injection. Let me know what everyone thinks.

Why did you make your gun with a 3" barrel? If you use a smaller size barrel and leave you chamber the same your gun will shoot alot farther and harder. Good job on the propane injection espically if it is your first gun.

i think u should get a closer pic. what do u use for ignition, a bbq lighter, stungun, flint spark?? and i agree with pimp, make the barrel smaller, u'll get a lot more power and distance. also, does it have a chamber fan??
i got connections with the modfia, watch who ur talkin to noob.

Yeah I use an electric BBQ ignitor. The ones you put a battery in. Also there is a chamber fan and I do get a lot of power from this cannon. I agree though a smaller but longer barrel would be better.
