Anyone know the pressure on those rubber caps... i think there not pressure rated... but if they are by all means use them... if there not just use a cleanout or a standard endcap for your own good!!
looks great!

Making something right? Or like righting something that's sideways?

im gonna make a small trial version of a piston gun and just wondering does the barrel on long coaxials ever sag down when its not pushed against the piston? cause a modded bushing is not that much to hold a long barrel
:?

You can get another bushing and mod it so it can act as a support.
I saw a picture somewhere.

All ya need to do is use a dremel or drill press to etch away the small lip that stops the pipe from sliding all the way through.
