Everyone will jump on you for using pvc unless it is strictly remote-fired. Even then it'll likely blow up eventually.

In a word, no. You may be brave, but that doesn't mean it won't blow up.

Are you sure that isn't ABS? Also, that looks like some of that off- centered Euro bushing coupler stuff...not a good safety record.

What makes you think this is a worthy hybrid at any X much less at 4 - 6X? Do you comprehend the energy levels you'll be dealing with here?

how dare u sacrifice a rocket pad in the name of spudgunning, they are hobbies that can work in unison.

shame on u

but anyway i will hop on the bandwagon, please dont use this, and go for a metal chamber, but u could always just use it as an advanced combustion.

it will run 4x, but if im brave i'll try 5-6x

What you may consider brave is actually "ignoring danger because of being stupid"
Now being brave may mean taking a risk, but bravery is not the kind of thing that will make you live a long life; especially when being a spudgunner.

How the heck did you even THINK that that pipe bomb could handle 6x?
If you did a little research on PVC hybrids you would have found out that eventually all PVC hybrids blow up.
Just begin with a combustion, and once you know what you are doing, try a hybrid; made out of STEEL.

All depends on where you live.
