Nighthawk Custom has always been known for their craftsmanship and with the release of our optics system we craft our optics mount with the same attention to detail. Without sacrificing any fit or function, we are able to give your 1911 sight options that you can change. Our goal was to create a system that is adaptable, diverse, easy, reliable, and blended seamlessly with the gun. As if it always belonged there. With all this in mind, Nighthawk Custom has created the most revolutionary sighting system ever conceived; the Interchangeable Optic System, or Nighthawk IOS for short.
