I ridicule myself for saying this, but...
A lot of the peep sights are a visual monstrosity - like bolting a brick outhouse to the Saturn 5 rocket IMO. I have a Williams that is very low and small, so doesn’t spoil the lines (even with the little bit of aluminium to raise the peep hole by 8mm). Why oh why can’t we add a picture instead of a link! If the Williams had thread adjusters instead of grub screws graunching into dovetails it would be perfect.
