AR15 Variation / Version for SHADOWRUN Fan Project

As with the armor design i have done before i wanted to show the factory model of an AR15 assault rifle in 2080s and some modified / adapted versions with equipment for the special expectations of the respective users. Among those variations is a sniper rifle and one that is specifically build and delivered to the BOPE - Anti Gang / Anti Terror Unit in Rio of 2080 ...so if some cop would see u with that on the street ... u definitely get a problem! I tried to design the platform based on an realistic concept, with the actual tech of the AR15 in the background, and then add some cyberpunk flavor to it. my goal was a comprehensible design.
