Yep - my feeling is that 5,000 is the top side for bolt life, and less for a suppressed or machine gun. I'm pretty sure it's even written somewhere.
I've replaced bolts at around 5k in the past. I've since stopped maintaining a replacement schedule or even really keeping round counts, but this is a reminder that it should probably be maintained with a designated hostility gun, at least. Training/fun guns can be ridden to failure without much consequence, obviously.
What's interesting is many of my bolts have almost double the mileage and are still fine. This includes the ones on my 11.5" and 12.5" uppers which are shot suppressed.
Of course, I know the pedigree of all of them.

Did it lock up again after the 40 additional rounds, or did you just decide to stop shooting at that point?
How much you selling it for ? It could yield a cool paper weight in the office, specially since it was celebrity shot , just sign it first. What do you gents consider on the low end of mileage for a quality BCG, high end? I am under the understanding that shooting suppressed will lower the BCG life, but is there a rule of thumb of about how much?
Grammar is not really my thing today I have a lot going on, I hope my question/ comment makes sense. It's something I often wondered.
