I am shooting a T/C omega 50 caliber with a williams peep and a front fiberoptic bead.

My peep is mounted at the very rear of the barrel in the rear scope threads. I use the Twilight hunting peep with as big an appeture as I can get.

I am also considering putting a KNS hooded crosshair front sight on my gun. Here is a link to a discussion of what I am talking about with pictures: http://www.monstermuleys.info/dcforum/DCForumID14/1201.html

Just not sure that I would be happy with this set up at dawn and dusk.
