I've got a SX3 longbeard edition with the rifle sights from the factory. The front fiber optic is like a .19 on a bow sight, at 40 yards it will basically fully cover a turkeys head and neck and almost block your aiming. Is there a way to replace that fiber optic end with a smaller diameter fiber optic? I know that a red dot Fast Fire 3 would be the perfect dot picture if I went with a red dot
