Hi all, I am trying to mount a peep sight onto my Lithgo 12 (my old eyes don't like unrecognizable blur that used to be the rear sight). I am trying to determine the size of the screw holes on the LHS of the receiver, I have some 6-48 screws on hand but they are too big. I also tried some 6BA, while they entered the hole they were clearly the wrong thread.
Does anyone know the correct thread size?
Thanks, Dave
