I have a Ruger Mark II bull barrel that I have had for a few years. The open sights and my bifocal specks aren’t working out too good these days so I’m thinking of a new sight for it. I have been looking at the Bushnel Holosight. I will be using it for small game and target use. Does any one use one of these sights and if so how does it stack up for small game hunting on the mark II?
