I got this idea to convert a Umarex Fusion 2 over to HPA, seems easy enough. Purchase a 13 ci bottle with adapter from AV and a QB79 tank block from Archer Air except the QB79 is currently not available and may never be again. Guys at Archer Air hope it will return but don't seem to really know. So is there any other option out there? I'm new to air guns and don't know what to even really look for.
Tuning CO2 to HPA conversion part question.

Muddydogs - I had this idea to convert a Umarex Fusion 1 over to HPA, seemed easy enough. Holly cow! Let me just say this is a job for someone who knows the risks involved and also knows what they are doing.
It had already been done, more or less, even before the Fusion 1 came out, in the form of a Flying Dragon XS60C PCP. It had a serious safety issue, something about wrong thread or air tube size.
Here are My Fusion 1 and XS60C in .177. Both shoot pretty good.
Here are a couple documents for you to read:
