Crosman 2250 hpa

Putting the finishing touches on my latest project... It's shooting 14.3 cph at 600 fps on 800 psi. I went ahead and pinned the valve in case I ever want to try it at 1100 psi, but it shoots so nice like this that I'll probably leave it alone. Running Disco parts on the inside that I picked up from Mangum Airpower.

If you can find a qb79 tank block , it would give you a much more support for the hpa bottle. You would of course have to  remove the threaded portion of the tube and anchor the tank block . Just a suggestion 👍

I thought about doing that, but decided to go this route. I didn't use hardware store fittings, these are heavy duty high pressure fittings with small orifices. They're really thick, and I stressed them with an empty tank and didn't see any flex at all.
