I have a thread similar to what you are asking on the rimfire forum. Do an advanced search in that forum for buckmark and you should find it. As far as a scope goes I have a 2X Simmon's on mine. It is far from the top of the line but has served me well. There are many more on here with more experience with pistol scopes so they can chime in here. But my recommendation is to stay with a 2X no matter what brand you get.
