Can you guys recommend what size drill bit is needed to drill a hole in a rear sight windage screw to accept the windage knob, and what size roll pin is used to secure the windage knob to the screw ? Thank you.

The hole in the knob is No. 52 drill, the hole in the screw was drilled at assembly no dimension was shown. The pin was solid .0635 X 9/16 and staked.

Generally speaking, a 1/16" drill and pin (.0625) will work fine. Though you can find hardened pins at .001" oversize too, but you get about 25 of them!
