Heckler & Koch is the world's second-largest manufacturer of handguns, assault rifles, submachine guns, machine guns and grenade launchers. Their UK HQ is an anonymous unit on an industrial park off Lenton Lane, NG7. It is responsible for selling guns around the world. Half a million people are killed by small arms each year, three quarters of whom are civilians. Literally millions of Heckler & Koch small arms are in use in around 90 countries. Heckler & Koch has licensed its weapons for production by repressive regimes such as Turkey, Iran, Mexico, Thailand, Pakistan, Saudi Arabia and Myanmar. Beyond the reach of EU arms embargoes, these countries have supplied the weapons to conflict zones such as Indonesia, Kenya and Sri Lanka.

H&K guns have been used in wars in Bosnia, East Timor and Sudan. The Heckler & Koch G3 rifle has been used by the often murderous militaries of Bolivia, Brazil, Chile, Colombia, El Salvador, Guyana, Haiti, Papua New Guinea, Paraguay, and Peru. These examples illustrate the unethical and uncontrolled nature of the industry in which Heckler & Koch is proud to operate.

H&K also supplies military and police units across Europe and the USA. The police team that slaughtered Jean Charles de Menezes on a London tube train was armed with powerful Heckler & Koch assault weapons. Heckler & Koch's UK office is NSAF Ltd, Unit 3, Easter Park, Lenton Lane, Nottingham NG7 2PX.
