I imagine then that even if the grub screw's threaded in as far it'll go the pin won't protrude out further than 1/2mm below the boltface
Difficult to see what it's purpose is then if it's sunk in there...
Should there be another spring dropped into the bolt first, then the pin, then the spring you've got and grub screw
I'm wondering if another spring would push the pin out beyond the bolt face
There seems to be some signs of the boltface rim deforming a bit at the point where it strikes cartridges to strip them out of the magazine, normal for zinc bolts anyway... could this sprung pin arrangement be there to push the round out of the mag
If it was a "Firing Pin" it would be in the centre of the boltface wouldn't it
but wouldn't it need to be protruding and fixed
