I'm confused about how the ball bearing seats under the windage knob on the rear A2/A4/NM sights.
Are there pockets milled into the rear sight base to allow the ball bearings to move around? Or?

There is a pocket in the windage knob that holds the spring and detent, which mate up to the spherical pockets machined in the rear sight base and there is a pocket in the carry handle for the spring and detent, which mate up with spherical pockets machined on the bottom of the elevation adjust wheel.  No pics right now, though.

That makes sense. I saw diagrams of the sight base with the "pockets" and thought they were through-holes!

Thanks again!
