Chinese scientists at the Xian Institute of Optics and Precision Mechanics have developed a fully functioning prototype of the "ZKZM-500 laser assault rifle."
The 15mm caliber weapon is being compared to an AK-47 because of its similar 6.6-lb weight, but it's firepower capabilities sound like something straight out of a sci-fi movie.
According to researchers who wish to remain anonymous, the ZKZM-500 fires an energy beam undetectable to the human eye that can pass through glass and cause the "instant carbonization" of human flesh from half a mile away.
