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