The TruGlo TG231K Tritium night sight set delivers reliable low-light target acquisition with self-illuminating tritium inserts that require no batteries or external light source. These precision-machined sights provide consistent sight picture in complete darkness for up to 12 years.
What Makes This Different
Unlike fiber optic sights that fade in darkness, the TG231K uses genuine Swiss tritium gas capsules that maintain constant brightness regardless of ambient light conditions. The green tritium configuration offers optimal contrast against most backgrounds while reducing eye strain during extended use. Each sight body is CNC-machined from steel bar stock for dimensional consistency and long-term durability.Key Features
