Nova Freedom / Seneca Aspen repair or conversion?

[Eagle Eye]

  I've owned a Nova Freedom for 4 years and it has been a good accurate pesting rifle. Now it is not functioning. I have the handle lock up and oring problem. I've degassed and oiled it but it still doesn't want to pump.  What is the best (easiest) way to have a functional air rifle again.  I've read all 9 pages of the conversion thread and hope I didn't miss any answers.  Can someone please answer some questions. If I don't want to remove the small "collection" tube, does a small regulated V2 ninja/gauntlet bottle fit or are the threads different? It looks like that bottle may be a little too large in diameter? Is there a drop block or some other way to make those bottles work?
Thank to anyone who can help.

If you pull it completely apart, you can replace the o ring on the final pump piston. Most likely some worn rubber peices clogging it up. All of the ball bearing check valves and air passages need to be cleaned as well.
