Before you replace your leaking '04 Cyborg solenoid...
It could just be an o-ring issue. My Cyborg has been sidelined for about 6+ years because it leaked out the back hole of the solenoid. All the o-rings looked okay and I cleaned and relubed it several times.
I figured it was from using too high of LPR pressure and didn't want to fork out the cash for a new solenoid.
I got an itch to fool with it today and isolated the problem to the o-rings on the rammer. Come to find out it's been the middle rammer o-ring the whole time. After 6 years of being a paper weight, the Cyborg can finally see the field again.
Just thought I'd post this here as a testament to Macdev's engineering greatness. Got a problem with your gun? It's probably an o-ring.
