FX impact x trigger help please

stuck on this trigger not moving like its locked..first off I rebuilt the regulator reinstalled and reinstalled the trigger no problem..reinstalled bottle and crock it and fired and looked for a leak of course the regular leaked removed and replaced all orings and of course I handle the gun upside down digging out the oring in the regulator chamber alls good reassemble and no leaks..except now the trigger won't work..if I crock the rife..I must pull the tigger pin to fire..stumped/

any advise Ill listen, thank u
 
may happen that unintentionally you turned the knob and the tension screw was loose?
this adjusters ..I didn't..but like u said I may have by digging out that tuff oring..what next.I am making a mistake by assuming the trigger not working..the gun has no pressure..bottle is removed..stillstump

There's a pin that does nothing but keep the sear from rotating too far, could it be above/below the sear blocking it?

I've locked mine up once or twice. I just took it all out and reinstalled. I just dumped everything so I'm not sure what I did wrong.
still stuck ..begaining to think about R&R the cock mech..first I'll give another try what u just mentioned..appreciate yours and every ones reply, thanks
