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
