Question about Swiss K31 bolt operation

[tiriaq]

The locking lugs are on the outer sleeve. You can see the sleeve rotate to lock. The serial number will be top dead centre when the bolt is completely locked. If the bolt handle is pulled back slightly, you will see the sleeve start to rotate slightly. When the trigger is pulled, you will see the sleeve rotate back to locked position. This is part of the safety interlock system to prevent the rifle from firing unless the bolt is closed. Almost all rifles have some sort of similar system built into them.

Thanks!

I just got a crash course in disassembly/reassembly of the bolt, when I accidentally took it apart while cleaning it. Man, that thing is complicated for a bolt-action rifle. Fortunately I found a good web page for directions other than the translated Swiss (it had pictures of the parts).
