There aren't many short automatic rifles. The recoil and muzzle rise of automatic fire makes anything under 16" in length inaccurate and impractical. However, the Swiss-based Kriss Systems has developed technology to compensate for the kickback of automatic fire, creating a short, light, and usable firearm named the Vector. Capable of shooting 1200 rounds/minute, the gun translates the horizontal energy of the recoil into vertical energy. To see the mechanism behind what Kriss is calling "The Most Significant Advance in Weapons Operating Systems in More Than 120 Years," check out the video after the jump.
