fire piston help

[enix]

CanDo: i would try to e-mail you or PM but you have it disabled. So what are the exact dimensions of your piston, the one you posted? I looked at your pics and went to the hardware store, now that I am home and look again i think i may have gotten my supplies a little large again. I would rather imitate one i know that works befor i start making to many of my own changes.

Thanks,
Evan
