This submachine gun is one of the most well known bullpop designed rifles. A very special design aspect is the magazine, it is located on top of the rifle, not below. See the videos for details how this works. The cartridge holds 50 rounds. Designed for a shooting distance of 200m, total range is 1800meters though. Differences between the versions: FN P90: original version FN P90 TR: similar to P90 but has a triple rail interface on top of the rifle. This allows to use standard attachments on the submachine gun FN PS90: civilian version: it does not contain the full auto fire mode
