Lowest Cost Method For Adapting Seneca Aspen / Nova Freedom To Run From A Bottle

I have a Nova Freedom with a broken Small Piston Head and Air Venturi will not sell me one. Currently running an ad in the classifieds, but if I can't find one, I would like to convert this over to run from a bottle. I don't want to put a bunch of money into this, so the most simple and least expensive way to get this to work is what I am looking for.

No need for a plenum or an adjustable regulator, just a safe interface for a thread on bottle. Plan to shorten the small diameter Air Chamber Extension Tube under the barrel to allow clearance for the bottle.

I sent a message to darkcharisma about options but they have not been on the sight since July, thus no response.
 
“ don't want to put a bunch of money into this”
Easier said than done. Good luck.

Yea, it is looking like that. Too bad the importer / marketer of the flawed product won't sell parts for it. That can't be more than a $15 part. I might just braze the broken part back on so it can hold the final stage 0-Ring in place and put it back together with a non functioning pump, filling with my compressor to get a few dozen shots perhaps per fill. It is a very accurate rifle so I am not too keen to sell it for parts......yet.

There is a guy on Youtube that simply chopped the small air chamber down, removed all the pump parts, chopped the stock up and threaded on a bottle with some brass fittings and it worked well for him. If I can find the right fittings made of the correct pressure rated stainless steel, his were brass, I would be happy with that setup.
