Tac-one not firing

[jjungl3]

just got a used tac-one not sure whats wrong with it but it wont fire. Ive done everything i can think of to fix it took it apart, checked the orings, trigger, oiled it, switched bolt spring etc.. everything seems intact. The guy that sold it to me didnt know what the problem was, he said it was shooting fine then left it sitting around for over six months then the problem starts, anyway i bought the mag thinking I could fix it and now Im stuck.. Sending it to AGD for repair would be my last resort, I want to try to find out what the problem is and fix it.

Ive got a crossfire 45/4500 LP, I know Low Pressure tanks are not recommended with agd markers but doesnt it have enough pressure to dry fire the marker?

ya first thing to do, get a high pressure tank. see if you can borrow one from a buddy or something.

Yep. You will have a very hard time firing a L10 automag with less than 600 psi input pressure.

A high pressure output tank is not recommended for 'mags - it's required.
It's entirely possible your tank just isn't giving the pressure needed to cycle the marker.

thanks guys,
thinking of
a 68/4500 pure energy
or a 68-70ci 4500 crossfire.
