Fiber optic sights are nothing new and neither are broken fiber optic rods. The fiber optic sights from L2D Combat have a small tapered beam integrated into the steel sight that is designed to protect the rod but still provide access to plenty of light.
The stainless steel sights are coated with DLC for a durable black finish and corrosion resistance. The rear sights feature plenty of surface for alternate methods of operating the slide. They are available in regular or suppressor heights.
