its just covering up the screws for ignition points

Ah, well that is real weird, I guess it turns out that ABS doesn't really tear!

It must have been somehow weakened/damaged however, since plenty of people use ABS just fine all of the time.

<s>The electrodes, I assume.</s>

Sorry, didn't realize there was another page.

That is not true.

I've seen pics of ABS shatter into pieces before, but that was a propane and oxygen injected shot, never would have expected it with just propane. Was it cold outside when you were shooting?

The extent of the failure is still far less than what a similar failure in PVC would have done. Notice that the cracks were able to stop themselves from propagating and let the gun remain mostly intact. You would never see that on PVC.

I would never use a cell core gun, but if I was held at gunpoint to fire either a cell core PVC gun or a cell core ABS, I would fire the ABS.

Thanks for the pics and glad you are OK

Yup - in that case, my BS-meter seems to be fine.

Given this incident, perhaps we need to reconsider construction materials. Inevitably, this will come up in the next ABS vs PVC debate.

Is/was the pipe old? aged? left in the sun? exposed to ozone? and, yes, was it cold out? have you ever used anything other than propane in it, like a solvent based fuel?

Man that gun is looking weird what was the design for it, is there a barrel attatchment. Lol. looks more like a pipe bomb to me.

the barrel screws on thats a 2 inch male threaded adapter on the end.

no it wasn't cold out it was like 80 degrees out
