They simplified the bolt vs. the A-Bolt. The additional parts on the X-Bolt were a result of adding the Bolt unlock button on the bolt handle, but bolt body design was actually simplified and the number of parts used there actually decreased...
It is a good safety feature IMO and one that works very well.
I'll just keep shooting small groups & keep killing stuff with mine. I'm under no illusions that dozens of hours of actual field experience with the rifle will make any difference in the current pissing match.
Pee on.
