how to build a combustion spud gun go to this link awsome vid i buid one exactly like this only with a stun gun

The guys in the vid are pretty dumb. They used CELL CORE ABS!!!
I'm not sure if ABS needs primer or not, but if it does they didn't do that either. And they forgot to give the fittings a quarter turn when they glued them.

EDIT: Abs doesn't need primer.

not to be critical but most people on this forum have already built gun like that or even better so an instructional video should

1. be in the How-to section

2. be safe (they used cell core)

3. be something new or not universaly known (like BCs instructional vid on propane meters)
