Thanks cayugad. I thought I heard that they were not replaceable, but called them and they are sending me some replacement fiberotic rods.

Also, for my Omega, the Williams peep sight is too low for the front stock fiberoptic post, so you either have to lower the front sight or raise the peep sight. When I called T/C they told me that they will ship me out a lower front sight at no charge since the stock one was too high. Hope it works. I will let you know.
