Note: Geissele’s Desert Dirt Color (DDC) finish refers to a variety of shades of desert terrain designed to better break up a rifle’s outline. These colors can vary drastically even between products from the same batch and ARE NOT intended to color match. Per Geissele Automatics, the only way to receive a uniform color across all parts and accessories is to have them painted with a different finish such as DuraCoat or Cerakote.
