I wrote earlier in this thread concerning TC or Pedersoli tang sights on a Woodsrunner. I initially tried a .450 high sight, but the TC aperture stem was not tall enough. At 25 yards Ithe stem was maxed out, and I was at POI. So I changed the front sight to .323 and that put the aperature stem about 1/3-1/2 height. That is optimum for me.
I am using a red fiber optic front, but it does not "pop" all that well for me. I think the fiber insert is poor quality, and generally I see green better. So I'll probably buy a new green one.
I will add the sight picture is amazing, and the rifle stacks balls. I think a green sight will be better on dark days in the woods, but the marginal red sight is still crazy easy to use. I think the factory brass sight would also be a viable height, and a nice focus point.
I am using the factory aperture disk in the TC sight. For me, I don't need the extra light by removing the disk, and going ghost sight mode. The Pedersoli is not tapped for a aperture disk, and as the name implies, it is a ghost type sight. Nothing wrong with any choice, and the ghost is probably the safest bet in all light conditions.
