Co2 adapter

I got a new madbull co2 adapter, and a brand new bottle of co2, but I can't fully thread the adapter on to the co2 tank and I'm not getting any presure into the adapter.

dumb question but co2 adapter or propane adapter? maybee sent the wrong one?

really dumb question, I have both and it is the co2 adapter I'm having problems.

maybee this will help, prolly not though ...

ya that didn't help.

Which CO2 adapter? Gauged or plain?

Gauged.

When you screw it on, does the gauge go up to ~600 psi? or nothing happens?

If nothing is happening either the adjustment screw is on too tight (not letting air through), the depression pin is not hitting the CO2 bottle pin (bad bottle design) or your CO2 is empty (have you tested?)

hehe, dumb question but did you get the co2 filled after you bought it?

Ya there's co2 in it. No it's just not screwing on all the way, but I can't figure out why, It came with an adapter peace for 12 gram co2 that screws in to the acual adapter and that works perfect.
