I bought a Leupold M8 4x fixed power scope from a guy at a show on Saturday. I gave $90. I also bought a set of rings and a mount and put it on my Guide Gun. Unfortunately I have reached the stage in life where the peep sight that I had on it no longer worked for me. Do any of you have any experience with this scope? It looks like it will work nicely on this gun. I was looking for a 2.5x but this one was a bargain and it was available...
