It was also at the KRISS booth that I then noticed the H.A.L.O H3 Adaptive Luminescent Optic sights made by DEFIANCE. The sight is a tritium and fiber optic hybrid, but unlike any other that I’d seen up to this point. The tritium is housed inside an aluminum cylinder which is then nested inside a fiber optic tube. The fiber optic tube is available in either green or red and is highly visible. I’ve been using an Ameriglo ProGlo front sight with 10-8 rear sight with good results, but would love to give the H.A.L.O. sights a run.
