A select-fire bullpup submachinegun produced by Fabrique Nationale (FN) that was developed for NATO during the early 90's. The P90 has an overall length of 19.7in (50cm), weighs 5.9lbs (2.9kg) empty or 6.6lbs (3kg) with a 50-round magazine and uses FN's specially developed 5.7x28mm ammunition (also used in the Five-seveN handgun). The P90 has been adopted by "more than a dozen countries in limited numbers" at the time of writing, according to REMTEK Arms. The gun has also been featured in video games such as Goldeneye, Counter-Strike and Rogue Spear: Raven Shield and also in the TV series Stargate SG-1 (thanks, Zerotime).
