Standard finishes will have a solid-color background that will cover up the carbon fiber (on stocks with Elite Tac shell) or fiberglass (on stocks with Standard shell). Elite Tac finishes (available only on stocks with Elite Tac shells) have the carbon fiber as the background. For example, Elite Tac Midnight would have a 40% carbon fiber background, 30% light gray and 30% dark gray. Standard Finish would have 40% black background, 30% light gray and 30% dark gray.
