Note: For ported barrel builds, we recommend using black iron sights without any colored areas, fiber optic rods, or tritium vials in case of excessive sight fouling. Carbon can cover and stain your rings and the pressure and heat from the gas can damage the rods or vials. Norsso is not responsible for any damage caused by sight fouling.
