Our Assessment: This FN PS90 represents the civilian adaptation of one of the most distinctive personal defense weapon designs of the modern era, developed by Fabrique Nationale Herstal as the semi-automatic counterpart to the military and law enforcement P90. Introduced to the commercial market in the early 2000s, the PS90 retained the futuristic bullpup layout, top-mounted horizontal magazine, and fully ambidextrous control scheme that defined the original P90 concept. Designed around compactness, balance, and high-capacity firepower, the PS90 exemplifies FN’s forward-looking approach to small arms engineering at the turn of the 21st century. Chambered in 5.7x28mm, the platform was engineered to deliver high velocity, low recoil, and flat trajectory from a compact package, making it well suited to the PDW concept that emerged in the late Cold War period. This example remains in excellent overall condition, retaining approximately 99 percent of its original finish with only faint handling marks noted. The bore is bright with sharp rifling and no visible erosion, rating 9.5 out of 10, and reflects careful use and maintenance. The factory FN ring sight optic remains clear and serviceable, and the polymer bullpup stock shows no notable wear, cracks, or defects, reinforcing the rifle’s clean presentation.
This offering is further enhanced by an extensive accessory package that includes multiple FN factory magazines, loading and maintenance tools, sling, brass catcher, and range bag, presenting a complete and well-supported system. The PS90’s unique magazine design, compact overall length, and balanced handling continue to set it apart from conventional carbines, making it both mechanically interesting and visually iconic. As a Gen 1 PS90 with strong condition, excellent bore, and desirable extras, this rifle stands as a highly representative example of FN’s modern PDW philosophy brought to the civilian market. -R.E.
