Everything you want in an optic solution. The IOS is adaptable to your needs and allows for a low profile RMR mount with the versatility to switch rear sight in a matter of seconds. With the dovetail cut in the slide each plate can be removed and still return to zero, allowing for quick and easy switching of rear sight without sacrificing aesthetic or function.

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.
