The better you can see your sights, the better you can shoot. TRUGLO brought fiber-optics to the shooting sports industry decades ago for this very reason. TFO pairs fiber-optic sights with 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 – providing the same bright sight picture whether you are in glaring daylight or complete darkness.
