The FN PS90 is a compact bullpup semi-automatic rifle chambered in 5.7x28mm and built around a closed-bolt, blowback operating system for consistent function and accuracy. The civilian-legal configuration features a cold hammer-forged MIL-SPEC barrel measuring 16.04 inches and an integrated ported muzzle brake to help control impulse. The design places controls and charging handles for true ambidextrous operation and uses a synthetic thumbhole bullpup stock for a short overall length without sacrificing a full-length barrel. The translucent, horizontally mounted magazine provides high capacity while maintaining a low profile.
