The SASR-17, or S-Advanced Service Rifle, is a modular pre-war assault rifle developed from a long-lost 2004 prototype design and later refined during the Sino-American War era by Thanoid Action LLC. The rifle features a distinctive silhouette often mistaken for the 10mm SMG, alongside a unique magazine eject lever system and forward-moving bolt assembly. Built from a mix of metal and wood, the S-Advanced Service Rifle is prized for its reliability, adaptability, and extreme modularity—capable of conversion into marksman, LMG, and various specialized configurations. Originally conceived by designer “S” and later revived by weapons engineer “N,” the design underwent 17 major revisions before reaching its final service form. Despite its wartime origins, the SASR-17 became widely adopted by both military forces and civilian markets, spawning numerous field-modified variants across the wasteland. A weapon defined not just by its design—but by its evolution.
