In late 1997, Steyr Mannlicher produced a rifle to his "Scout" specifications, with Cooper's oversight during the engineering and manufacturing process. While not a spectacular sales success, these rifles nevertheless sold quite well and are still being produced. Cooper considered the Steyr Scout "perfect" and often made the point that "I've got mine!" Riflemen regard Cooper's development of the Scout Rifle concept, and his subsequent work on the evolution of the Steyr-Mannlicher Scout rifle, as his most significant and enduring contributions to riflecraft. Ruger (Gunsite Scout Rifle), Savage Arms, Springfield Armory, and Mossberg have made versions of the Scout Rifle as well.
