I have changed nothing to my Brno 460 WBY Mag.I kept it as it is.I a difficult situation with any dangerous game I don't want to find a charging animal trough my scope.Swing of scopes and all these fancy gadgets works very nice and I'm Impressed with accuracy on quick release mounts but in the heat of the moment it takes time and time is last thing that you have.Straight forward open sights is the best for me.We are all used to it as most of us was tought to shoot with open sights.I remember hitting anything bigger than a sigaret but with my old BSA Meteor airgun when I was a child.A DG rifle must be straight forward and very simple to handle.A Basic rifle with a lot of power!!!
