Its my second modeling of an assault rifle, Just love the way Scar looks, so inspirational :P Modeling took me about 3 to 4 hours, tried to imitate the outdoors lighting and it looks pretty decent, Used one key light to be sun, then eased the shadows with fill light and added a bit of sky texture in global illumination and there u go. Hope U dig it!!!
