HiViz PMN301 LiteWave H3 CompSight Tritium Fiber Optic Front Sight

The HiViz PMN301 LiteWave H3 CompSight transforms low-light shooting accuracy with dual-illumination technology that combines green tritium inserts with fiber optic elements. This bead replacement front sight delivers consistent sight picture acquisition in any lighting condition, from bright daylight to complete darkness.

What Makes This Different

Unlike standard front beads that disappear in poor lighting, the PMN301 features HiViz's proprietary LiteWave technology that automatically adjusts brightness based on ambient conditions. The green tritium provides constant illumination for 12+ years without batteries, while the fiber optic elements gather and concentrate available light during daylight hours. This dual-illumination system eliminates the guesswork common with traditional iron sights.

Key Features

• Green tritium insert provides 12+ year battery-free illumination
• Fiber optic rod automatically collects ambient light for daylight brightness
• Universal threading fits most shotgun and rifle barrels (.125" to .140")
• Precision-machined aluminum construction with matte black finish
• CompSight profile reduces glare and improves target acquisition speed
• Weather-sealed design prevents moisture infiltration
• Tool-free installation with included thread locker compound

Field testing demonstrates the PMN301's effectiveness across multiple shooting disciplines. Competitive shooters report faster target acquisition during rapid-fire stages, while hunters appreciate the consistent sight picture during dawn and dusk periods when game movement peaks. The sight maintains zero through temperature extremes and heavy recoil, making it suitable for magnum rifle cartridges and high-volume shotgun applications.
