Default AR upper maximum useful life?

I was talking to another high power shooter today. He was explaining to me he had over 10,000 rounds on his AR he uses in 100-200 yard reduced matches. Original barrel but on its 3rd bolt. Let's just forget about accuracy for a minute. Is there a number of cycles a upper receiver can take before cracks and stress fractures can happen? A recommended discard round count? At what point do you worry it's going to come apart on you?
