Converted my QB79 CO2 rifle to PCP at 800psi. Tried to mirror the pressure in the CO2 cartridge to 800psi regulated from 3000psi bottle.

My previous valve had started to leak and the gauge wasn't accurate anymore. I thought about tearing it apart and replacing seals and putting a new gauge on it, but for the cost it's hard to justify spending nearly as much to fix the old valve as it does to replace it with this one. I don't know if it'll last as long as my old one, but I'm going to give it a shot.

Leaked the first use - I doubt this regulator would ever reach 4500 psi.One star to wish upon. It might work - if you wish hard.
