RE: Got a Knight Rolling Block on the way.
You might look at the Burris Fulfield II scope. I bought a 3-9x40mm that has a ballistic plex crosshair. I have not shot it yet but the dots on the ball plex are bigger than some and I believe that it will make a good bullet drop compensator. Price is usually around $200 or a little less. By the way I think you are going to like the rifle. I have looked at it and consider it the best of the two new ones from Knight. Like the lack of the plastic carrier also.
