PLEASE NOTE:  Color matching Desert Smoke™ or Olive Drab Green uppers to existing lowers is extremely difficult due to variations in the anodizing process.  It is HIGHLY recommended that customers purchase matched sets from their local dealer if they intend to have a color matched upper and lower.  Another option is to order a contrasting color.  In fact, Franklin Armory® builds some complete firearms with receivers in ODG/DS because of the favorable appearance.
