I just got some williams sights and I don't know what size to tap for?

The most common sized sight screws are 6-48 and 8-48.

Didn't the Williams sights come with mounting screws??

Can you measure the diameter of the screws that came with the sight? They are almost surely 6-48 but if you can measure them we can be sure.

It just dawned on me that the scope mount screws on almost any modern rifle (factory) are 6-48. If the sight screws fit an existing hole in a modern rifle they are 6-48..
