The Ultradyne C4 Offset Folding Sight Combo (brand part no. UD10880) is a fixed backup iron sight set, not a light or laser, machined from 416 stainless steel and aircraft aluminum for a lightweight, compact package. The rear sight uses a positive-click, oversized windage knob that doubles as storage for a spare front sight detent, and the whole set folds flat when the shooter is running a primary magnified optic.
