Careful with that axe Eugene, er K31 diopter tool.

Sorry for the 1969 Pink Floyd song reference, but you get the idea.
Amazing the things you see when club rifles are returned.

From what height was it dropped?

 

[diopter]

Doubt very much it was dropped.

Swiss diopter mount tool, Flat narrow part into slots on nut, wings to help turn.
Thinner section of one wing is for slotted screw holding front sight on to K31 front sight ears.

Normally looks like this. Note there are variations with and without the round holes drilled on the nut. Maybe the reason most do not have the round holes.

Not like this.

Story not given to me. Many of our members are farmers I wouldn't want to arm wrestle with. Could be nut was hardened too much or missed being annealed and is brittle.

Looks like King Kong tightened those mounting bolts and then broke a chunk off.

Club rifles? A deposit would seem to be required.

Grizz

Got quite a few back from their family after the club member died.
