My Guide Gun has a Leupold 2.5x Scout Scope in QD mounts and backup ghost ring sights. If you want a more conventional scope the Leupold 2.5x was a great scope they discontinued because Leupold no longer makes reasonable scopes. It should be available out there with a bit of searching.

I’m shooting a 260gr cast bullet in my Guide at a bit over 1,900 fps and I just sight in at 100 yards because the average shot here is 25 - 120 yards.
