Knight Disc does come pre tapped for a scope and has excellent fiber optic sights I believe. There is currently a $50.00 rebate from Knight when you figure in the price of the rifle.... Hope this link works for you.

The Knight Disc is probably not on the Knight Web page because it could be a discontinued model which is why they are selling them so cheap. That does not mean they are any less covered by Knight. It just means there are new models out that they are pushing.....
