PSR goes over the Nylaug and affordable real steel clone of the famous Steyr AUG. This is a semi-automatic built using surplus AUG parts kits combined with a 3D printed carbon-fiber nylon-6 receiver and a KAK AR-15 style barrel and flash hider. Though it loses the original's quick-detach barrel, the NylAUG offers a significantly improved Titus Arms AR15 trigger pack and a better-tuned gas system compared to the factory AUG, all at a substantially lower cost.
