A HK417 assault rifle manufactured by Heckler & Koch is pictured during a guided media tour at their headquarters in Oberndorf, 80 kilometers southwest of Stuttgart, Germany, May 8, 2015. Perched at the top of a steep winding road in the lush green forests of Swabia in southern Germany sits a fenced-in compound of unremarkable boxy white buildings that house a company under seige. Heckler and Koch (HK) is one of the most successful gun manufacturers in the world. Last year, Berlin abruptly reversed course on arms exports following a storm of media criticism. Tighter restrictions introduced by Economy Minister Sigmar Gabriel ground HK's Middle East business to a halt, hammering revenues. Picture taken May 8, 2015. REUTERS/Ralph Orlowski
