Flush Nut what?

[Arnhem44mad]

Anyone have a clue what's going in with this flush nut sight?

It's on a friends garand and when he got it had all original ww2 parts and clear cartouches on stock. Probably an unmolested example. But the sight nut has me wondering...

Thank you!

Its hard to see in the picture but it "looks" like someone installed a post war T105 windage knob nut

Looks like what others have said, but that receiver/sight has been refinished in my opinion.
