The AR-15 is the most popular rifle in America, and the most reviled. A civilian variant of the U.S. military’s standard-issue M16, the AR-15 has gained recent notoriety for its use in mass shootings in Newtown, Aurora, San Bernardino and Orlando’s Pulse nightclub; the gun is also the centerpiece of an ongoing high-profile lawsuit against gun manufacturers.
