Trijicon night sights are illuminated iron sights that increase the ease of shooting at night and in low light conditions. No batteries are required, and the glowing tritium gas is housed in a durable cylinder and capped with a sapphire jewel for even light distribution. Silicon cushions protect the ampules even further, and the aluminum construction easily replaces your factory sights.
