The TruGlo TG231S2 Tritium night sights deliver reliable low-light target acquisition with self-illuminating tritium inserts that require no batteries or external light sources. These sights provide consistent aiming reference in complete darkness for up to 12 years through Swiss tritium technology.
What Makes This Different
Unlike fiber optic sights that depend on ambient light, the TG231S2 uses genuine tritium gas capsules that glow continuously without fade throughout the day-night cycle. The green tritium configuration offers optimal contrast against most target backgrounds while maintaining the traditional sight picture shooters expect. Steel construction withstands repeated recoil cycles and environmental exposure that would damage plastic alternatives.Key Features
