An adjustable front sight includes a carrier with a spiral sighting blade mounted for rotation within a base attached directly or indirectly to a barrel. A progression of sight lands is formed along a peripheral surface of the spiral sighting blade. Rotation of the carrier in opposite directions moves different sight lands into a sighting position at varying heights above the barrel for making elevation adjustments.
