Walther WA 2000

[5][6] Only 176 were built due to its high manufacturing cost, making it one of the rarest and most sought-after production firearms ever made.

The WA 2000 was designed in the late 1970s and early 1980s[citation needed], in response to the Munich massacre at the 1972 Summer Olympics.

The barrel is set in line with user's shoulder to reduce recoil and the bolt mechanism sits behind the handgrip in a 'bullpup' arrangement.

[4] The rifle uses single stack box magazines with a 6-round capacity, which weigh 0.4 kg (0.88 lb) when loaded.

[11][better source needed] The rifle was used by some German police units, but production was stopped because it was too expensive to achieve widespread sales.
