Just before the beginning of the 5th Corporate War, MTI and Omni-Tek undertook a joint venture to produce a close-combat flechette-based assault rifle, this rusty PF55. The all-purpose bullet is shaped into metal darts, and enclosed in a sabot that protects the dart during propulsion and firing. The darts are small, and rely only on their aerodynamic shape for stabilization. It yields low accuracy but high damage output.
