Developed as a reinforced improvement to the earlier Model 1908, Warner & Swayse's Model 1913 scope was the second purpose built sniper scope issued to American military personnel, and saw service during World War I. The scope's weight, complexity, and prismatic design all negatively impacted its performance on the battlefield. By World War II, the United States relied upon simpler civilian hunting scopes for sniper rifles.
