I am looking for a new sight for the Bowtech Patriot. What I want is an adjustable yardage single fiber optic sight pin in 0.019 fiber. I need for the fiber to be completly protected from accidental breakage. Either a lense on the sight or a fiber pin that is incased in metal or plastic. I prefer for the pin to come from the bottom. I have had the Cobra Extreeme slide, Tru-Glow, and one other sight in the past. They re all good but do not offer the smaller fiber or a rugidized fiber sight pin.
