TruGlo TG13FN3A TFX Night Sights - Green Tritium Fiber Optic

The TruGlo TG13FN3A TFX night sights combine tritium and fiber optic technology to deliver 24-hour sight visibility for tactical and defensive applications. This sight set features a green tritium front sight with white outline and matching green tritium rear sight, providing consistent sight picture in all lighting conditions.

What Makes This Different

Unlike standard iron sights or single-technology night sights, the TFX series integrates both tritium vials and fiber optic elements in a single sight body. The tritium provides illumination in complete darkness while fiber optics gather ambient light during daylight hours. This dual-technology approach eliminates the brightness gaps common with tritium-only sights, delivering consistent visibility across all lighting scenarios.

Key Features

• Tritium and fiber optic combination for 24-hour sight visibility
• Green tritium front sight with white focus ring for rapid target acquisition
• Green tritium rear sight for consistent sight alignment
• CNC-machined steel construction with protective sight capsule
• Snag-resistant design with angled rear sight face
• Fits standard dovetail cuts without gunsmith modification
• Self-illuminating tritium rated for 12+ year lifespan

The TFX sights excel in low-light tactical scenarios where rapid sight acquisition matters most. Law enforcement and military professionals rely on the instant visibility these sights provide during building searches, vehicle stops, and other critical situations. The green tritium color offers excellent contrast against most backgrounds while maintaining night vision compatibility. Weather-sealed construction protects the tritium vials and fiber optic elements from moisture, debris, and impact damage.
