There are no regulators for the airguns you have that do what you want. Even if there were I don’t know they would send it to CHINA where you are located.
Benjamin Marauder and condor all I have. Can work in these two PCP regulator all I need.
No-one has a reg for the Marauder and when properly tuned you likely won’t need one.
For the Condor you could use a paintball tank and reg connected to the CO2 adapter from Airforce. The outlet pressure is based on what you buy
so the vendors for what you want would be JDSairman and Airhog.
I was able to custom order a 1350psi regulator from Nitro Duck. I wonder how that would work through the Co2 adapter? 😯
