The PS90's bullpup configuration places the action behind the trigger, contributing to a compact, well-balanced carbine with a 16.04 in barrel. Its bottom-ejecting design supports ambidextrous use and keeps ejection away from the shooter.
This example features the factory integrated 1x Ring Sights optic housing marked "Ring Sights," with "PS90 cal 5.7×28" on the optic strap. A left-side Picatinny accessory rail segment is installed on the housing, and an additional aftermarket accessory rail assembly is included but not installed.
The action is straight blowback and closed bolt. The tan polymer frame and stock incorporate ergonomic handholes and a left-front sling loop. Length of pull measures 13.5 in, and the barrel is fitted with a slotted cylindrical flash hider.
Feeding is via top-mounted translucent magazines with a rotary feed path. Capacity is 50+1, and this rifle includes three 50-round magazines to take full advantage of the platform's design. Markings include Fabrique Nationale Herstal BELGIUM and FNH USA Fredericksburg, VA, with country of origin listed as Belgium.
