I don't think an HPA/CO2 rig would work with the conversion due to the space and how it works. I've thought about it before and I just didn't see where you could tap it and run external due to the 12 gram cartridge.
I would not recommend this rifle with the CO2 conversions due to a lot of FPS fluctuations affecting accuracy, however, I would recommend this rifle if you kept it spring and just did minor upgrades. I've actually made on into a decent shooter before for a cheap price.
The concept for the CO2 conversion was cool, but not very practical for going out and using it in the field. Unregulated CO2 (about 800 PSI) in that tiny little bulb will have a ton of fluctuations; look-up a video review on it and you will see.
