HIVIZ AR-15 Steel Fiber Optic Front Sight with Interchangeable Red & Green Lite Pipes

The Hi-Viz AR-15 Steel Fiber Optic Front Sight is a drop-in replacement for standard A1- and A2-style front sight posts that brings precision and speed to your rifle's sight picture. If you shoot AR-pattern rifles in varying light conditions—from bright range days to thick timber or overcast hunting seasons—this fiber optic sight delivers a bright, fast-acquiring aiming point without batteries or electronics. The U-shaped fiber optic rod gathers significantly more light than conventional straight-rod designs, making target acquisition fast even when conditions get dim.

Installation requires no gunsmithing; the sight post simply replaces your existing front sight. The kit ships with four interchangeable lite pipes—two red and two green—so you can swap colors to match your preference or lighting conditions, and you've got spares on hand if a rod ever gets damaged. A removal tool is included to swap rods quickly in the field. Elevation adjustment is handled with the supplied sight wrench and works in 180° increments, offering up to 2.5 inches of total adjustment at 100 yards to dial in your zero.

Built tough for duty and hunting rifles alike, this sight combines the speed of a fiber optic with the reliability of a fixed front post. It's an affordable way to modernize an older AR build or upgrade a rifle you already trust.
