I've forgotten. Let's figure it out. The windage is about 1 moa per click and the elevation is about 3/4 moa per click on that sight on that gun. The windage is 8 clicks per revolution. The rear surfaces of the front and rear sights are 6 11/16" (6.63875") apart. So. . .
8' = (8/60)° = 0.13333…°,
and that means,
0.13333…°/turn
sin(.13333…°) = 0.002327
1 / (6.6875 × 0.002327) = 64.257
So it looks like 64 TPI is likely. 2-64 is a standard UNF thread, but it certainly could be a special.
