I'm wondering if anyone has tried using a barrel with only a double bead as the sight when shooting slugs. Seems that it would be greatly superior to only a single bead since you would be able to align the rear bead to exactly cover the front bead to get a straight sight plane, both horizontally and vertically.
This would be as an alternative to buying a whole new barrel with rifle sights.
