The WA 2000 was designed in the late 1970s and early 1980s , in response to the 1972 Summer Olympics Munich massacre . The bullpup design was chosen because it would allow a standard length barrel to be used whilst the overall length would be shorter than a conventional rifle . The WA 2000 had a quick-detachable scope mount with a weight of 0.96 kg ( 2.1 lb ) . The rifle did not have iron sights . The most commonly used optical sight was a Schmidt & Bender 2.5 – 10 × telescopic sight . Without scope the rifle has an unloaded weight of 6.95 kg ( 15.3 lb ) and a loaded weight of 7.35 kg ( 16.2 lb )
