Pete,
I imagine it depends on how hot your rounds are and how brutal your system is. Hot rounds hammer the bolt and early unlocking puts a lot of strain on extractors. If you don't mind 50fps your AA Hard-Use bolt should last the life of the gun (10-30K rds)
If you carry a spare bolt in the buttstock you will more than likely never need it.
