Adjustable Power Settings – Do they work if I install an aftermarket REGULATOR?

[JungleShooter]

Quick question:
A PCP with adjustable power settings – like the Kral Puncher Breaker.
If I install an aftermarket regulator – can I still adjust power, or is that now set to a fixed power setting because of the regulator?

Yes. Form lower than the reg set pressure,up to the Reg's seg pressure.

I don't know what knobs you can twiddle on the Puncher Breaker but if there is a transfer port restrictor screw (aka metering screw) or a hammer spring adjuster, you can adjust the power.  The former is preferable to the latter if you intend to make large changes (e.g. cutting power in half).
