Note: Geissele’s Desert Dirt Color (DDC) finish refers to a range of desert-inspired shades designed to break up a rifle’s outline. These colors can vary drastically even within 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.
