Front sight dia?
 

I have a thompson triumph with a factory front sight as I have changed the back to a williams peep. What I don't like is the Dia. of the fiber optic on the front sight at 200 yds it covers up a 20" circle the fiber optic measures .060. I called williams and they said thats the smallest they make. My question is, does does anyone know of another company that makes a smaller dia. fiber optic for the Triumph?
Thanks Mercer

mercer, no, but I don't like the fiber optic sights - period. It may appear bigger due to the 'glow'. You might want to try what I did. Put a little dab of white out on the side of the front sight facing you. Makes my life a lot easier.
