I have a friend who lives in Nevada which has historically always been NFA friendly. The new governor and legislature etc though are talking about reversing course on the subject.

As far as I know not many states have ever really completely reversed course from legal to illegal. It's always been the other way around.

He's asking me about what would happen and I told him simply I don't know.

For people who already own suppressors and the like, I don't know what they can do as it's already legally owned and no grandfather clause is being discussed.

I can see how it would prevent any new stamps from being issued, but what about existing ones, or say suppressors brought in from out of state?
