Graco Pro Shot II 20V Needs work but it does run

Description

Graco Pro Shot II 20V Since I don't know the extend of what work needs to be done on this unit, I'm listing it as "For parts or not working".
Only (1) battery charges and it powers when you squeeze the trigger. I had Parrish Equipment (Nashville) look it over  and the interior valve is stuck and will need replacing ( part.) I didn't do a full inspection; this was just a courtesy look by Parrish.
Make me a reasonable offer. Local pickup only.
