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.

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.
