Heckler & Koch

About

Heckler & Koch was founded by Edmund Heckler, Theodor Koch, and Alex Seidel in 1949. It emerged out of what was leftover from the Mauser company. It was not until 1956 that HK started to manufacture firearms. Prior to that they manufactured tools, sewing machines, gauges and precision parts. HK has a history of innovation such as incorporating polymers in weapon designing and the use of integral rails on handguns. They also developed modern polygonal rifling, noted for its high accuracy, increased muzzle velocity and barrel life.
