Have about half my airguns scoped, half open sights and two with SeeAll sights. Scoped guns for precision, open sights for close range pesting or plinking out to just past 80yards, would shoot further but gets hard to see targets that far into the woods on my property without magnification. SeeAll sights are ok, but I prefer them for fixed distances. Currently using them @ 10m indoors (for winter) on guns that didn't come equipped with opens. Have used them at 25 and 50 yards with air rifles.
