TruGlo TG-TG92B Glo-Dot II Tritium Night Sight Set .410 Gauge Red

The TruGlo TG-TG92B Glo-Dot II sight set transforms low-light shooting accuracy with tritium-powered illumination that requires no batteries or external light source. This red dot sight system delivers consistent target acquisition in complete darkness and bright daylight conditions. Professional shooters and hunters rely on tritium technology for its 12-year lifespan and weather-resistant performance.

What Makes This Different

Unlike fiber optic sights that depend on ambient light, the Glo-Dot II uses Swiss tritium gas capsules that glow continuously for over a decade. The red illumination provides faster target acquisition than traditional iron sights while maintaining the reliability of fixed sight systems. Each sight undergoes precision machining to ensure consistent point of impact and maintains zero through thousands of rounds.

Key Features

• Swiss tritium capsules provide 12+ years of continuous illumination
• CNC-machined steel construction with corrosion-resistant finish
• Red tritium inserts for rapid target acquisition in all lighting
• Compatible with .410 gauge shotgun platforms
• Precise windage and elevation adjustment capability
• White outline rings enhance daylight visibility
• Impact-resistant design rated for heavy recoil applications

Field testing demonstrates the Glo-Dot II maintains accuracy standards across temperature ranges from -20°F to 160°F. The tritium illumination intensity remains constant regardless of humidity, rain, or snow exposure. Competitive shooters report improved split times during rapid-fire sequences, while hunters appreciate the sight's performance during dawn and dusk shooting windows when game activity peaks.
