Remove Rear Sight

[gmwhitehair]

Could someone tell me how to remove the rear sight from a Knight muzzleloader; either a Littlehorn, Revolution or Wolverine. They all appear to be the same. I removed the front screw (toward the muzzle) but am not sure what to do next. Looks like it might be on a dovetail but I don't want to try banging on it if there is another screw or something to be removed. Any assistance would be appreciated. Thanks.

I have an older original disc that has the non ramp rear sight. The front mounting screw is the easy one the rear mounting is hidden under top half of sight. There is two small allen head screws just in front of the v-notch, loosen the one closest to the front screw until the top half of the sight can be rotated to gain access to the rear mounting screw. hope this helps.
