So I've decided to dip my toes into HPA by converting my sawn off. From looking on google I need an adapter for the valve like this

Obviously I also need a tank, line and regulator so I'm thinking this package from high pressure airsoft.

Is there anything I'm missing, or am I good with these?
Thanks, all help is appreciated
