As far as I know, Knight is no longer SELLING rifles. Which means customer service operations are burning through someone's pocket, probably while they look for a buyer to restart production.
What happens if they don't? Without a revenue stream, customer service will eventually fold. I would not depend on it being around for any amount of time.
I'm going by internet rumors, so correct me if I'm wrong and they do have some sort of revenue stream or confirmed plans to start selling guns again.
I have nothing against Knight guns, except for a few flop models (that probably led to their downfall) they made some fine guns. I just don't see a company without income staying around.
