Tac One Problem

[Riddick]

Just wondering if anyone could help me. My tac is aired up and not shooting, not even dry firing. There is air in it, its just not poppin. What could be wrong? Thanks.

Hope you don't have a low-pressure output tank...
850 psi minimum for my gun to cock.

Is it new to you? Need more info.

Does the trigger rod "click" against the back of the trigger?

I've used it before and its worked fine. But now I just aired up up to test out the new barrel and it won't shoot. I need to get more air, but I'll check the "clicking" tomorrow. I'ma head down to the local shop and see if they have time to take a look at it. Thanks for your replies.
