Sear stick and double firing....

[Boydster]

I removed my X-Valve and installed my Classic valve because I only had CO2. Everything worked perfect with the X-Valve and whenever the Classic valve got put on the sear would stick in the back position. Not completely back but maybe a penny's width from the normal ready position. After a few seconds it would pop back out. (Same exact setup as before, only the Classic valve is on.)(Also, I'm using a CO2 tank that's anti siphoned and I have an X-Core installed.)

Beside that problem, sometimes when I pull the trigger, the gun would double fire. Similar to pull and release firing. What's this?

Take the on-off out and clean it. It may be sticking. Are you using the same bolt spring in both? Try a new bolt spring and possibly a shorter powertube spacer.

I'll try that, thanks.

Also if you have a ule body, make sure the field strip/grip frame screws are tightened approx. the same, Also check the pressure you are getting to the gun. Good luck
