If you remove the aperture disc from the tang sight, and use the 1/4" diameter mounting HOLE in the sight as a " ghost ring sight", you should be able to hunt with it in even very poor light conditions. The eye will still automatically center the larger hole around the front sight.
I used a peep sighted gun to hunt my last Wild Boar, on a very overcast January Day in Tennessee. If I had left the aperture in the sight, It would have been useless in the gray light I had that day. Worse in aiming against the dark fur of the boar I shot. But, I removed the disc, and put in my shirt pocket, just in case the sun decided to break through before I saw my boar. I ended up using the "Ghost-ring", and put the bullet exactly where I aimed. :thumbsup:
