A bullpup firearm is one with its firing grip located in front of the breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range and ballistic effectiveness.

The Walther WA 2000 is a semi-automatic bullpup sniper rifle produced by the Carl Walther GmbH Sportwaffen company from 1978 to 1988. The WA2000 was introduced to the markets in 1981 and 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. The Bundeswehr Museum of German Defense Technology in Koblenz has one of this specimen in its collection.
