The bolt has the rivet.
That is a WW2 alteration.
Prevents incorrect reassembly, but does not make disassembly any easier.
It is really easy to tell if a Mk. III bolt is assembled incorrectly. Lots of information about this.
It is worth experimenting to learn how not assemble the bolt. If a bolt has a bit of wear, it is possible to create the dangerous configuration without much effort, although it won't happen unless someone does it.
I did see a bubba'd Mk. III which had come into a shop. It was sitting on the rack with its bolt misassembled. Scary. I set it right.
