When you need to make a fast and accurate shot brightness counts. Truglo brought fiber-optics to the shooting sports industry years ago for this very reason. They have now paired them with their tritium night sights to create a consistently bright sight picture – day or night! Truglo patented combination of Tritium and Fiber-optic technologies unites the best of both worlds. Whether you are in glaring daylight or complete darkness you can count on TFO to provide a bright and reliable sight picture.
