The Heckler & Koch WSG2000 (Weitreichendes Scharfschützengewehr, Long-range sniper rifle in English) was a prototype bullpup sniper rifle proposed in 1990. It was planned to be chambered for 9x90mm MEN and would have been ideal as an anti-materiel rifle. The WSG2000 only ever reached the mock-up stage and was never built as a fully-functional rifle.
