What do you think about the Blaser R 93? Any faults?

I got one in use for 8 years now. One of my workhorses.
It does not have anything I would call a fault - but it does have construction-based characteristics that make it different from conventional bolt actions.
Any specific questions?

A friend of mine had some trouble with the firingpin-cockinglever. And the construction of the bolthead seems to be weak.

What kind of trouble?
The bolt head is actually a very strong construction.
