The PS90’s bullpup design places the action behind the trigger for compact handling while retaining a 16.04 in barrel. Its bottom-ejection system is integral to the platform and supports consistent, controlled ejection under use.
This railed-receiver variant omits the integrated optic in favor of a full-length MIL-STD-1913 Picatinny top rail. The receiver features a forward charging handle recess and a sling loop on the left front of the receiver housing for straightforward carry setup.
The rifle is chambered in 5.7x28mm and uses the top-mounted longitudinal magazine system. Capacity is 50+1, and this example includes two factory 50-round translucent magazines designed specifically for the PS90.
Construction centers on a polymer frame and stock with an integral trigger guard and forward handhold. It operates via a straight blowback action and carries a crowned barrel with a slotted muzzle device. Markings include Fabrique Nationale Herstal BELGIUM and FN COLUMBIA SC, with country of origin noted as Belgium.
