The Walther WA 2000 is a semi-automatic bullpup sniper rifle produced by the Carl Walther GmbH Sportwaffen company from 1982 until 1988. It was produced in three different calibers. Production of the rifle was limited and it was shortly stopped because it was too expensive to achieve widespread sales and not robust enough for military use as a sniper rifle. Only 176 were built due to its high cost, making it one of the rarest and most sought production firearms ever made.
