Huben Power makes a whole line of AirForce regulators. They now have a product that will work with big bore. It has a 120CC plenum so you should not lose as much power from regulating. Primarily for Condor/Talon but it just connects up to your existing valve m18 fitting. There will be some loss of power, 120CC is less than the volume of your barrel so the pressure will drop once the plenum is exhausted.
