I have a QB running on HPA and would like to know what my options are to re-fill my tank....

I'm lazy and don't think a hand pump will work for me ...

I would need to pull the barrel off in order to get my tank off to take it somewhere so I need to be able to fill it on the gun ...

I am looking into a scuba tank and will need to get the filler hose and guage ....is this my best route or is there a better way?

Thanks for any advice ...

Shawn
