Have you figured out how to clean the gas passage?
I poured Hoppe's into it and let it soak for a couple days, then blasted it out with brake cleaner followed by compressed air.
That said, the build-up in there is self-limiting like an AR's gas tube; It'll only become so restricted. I only cleaned it because it annoyed me knowing it was dirty in there.
