The FN PS90 Standard is engineered as a civilian-legal semi-automatic carbine, adapting the design principles of the FN P90® Personal Defense Weapon. Its bullpup configuration and proprietary 5.7x28mm cartridge provide a compact, maneuverable platform with low recoil impulse and high velocity performance.
Key Features
Compact Bullpup Design
The PS90’s bullpup architecture positions the action behind the trigger group, significantly reducing overall length while maintaining a 16.04-inch barrel. This design optimizes the rifle for close-quarters engagements and tactical vehicle operations, enhancing maneuverability without compromising ballistic performance.
5.7x28mm Cartridge Integration
Chambered in FN’s 5.7x28mm, the PS90 delivers a flat trajectory and reduced felt recoil. This cartridge features a lightweight, high-velocity projectile designed to mitigate over-penetration while providing effective incapacitation within its operational envelope.
Unique Top-Feeding Magazine System
The rifle utilizes a transparent, horizontal 10-round magazine that feeds directly into the receiver from the top. This design minimizes the rifle’s profile, protects the magazine from external impact, and allows for immediate visual confirmation of ammunition status.
Ambidextrous Controls and Ergonomics
Designed for full ambidextrous operation, the PS90 features a forward-mounted magazine release, ambidextrous charging handles, and a bottom-ejecting spent casing system. This configuration ensures seamless operation for both left and right-handed shooters in dynamic environments.
Integrated Optical Mounting Platform
The PS90 Standard includes an integrated MIL-STD-1913 accessory rail, facilitating direct mounting of various optics and targeting devices. This allows for precise customization to individual shooter preferences and mission requirements without additional adapters.
Robust Construction
Constructed with a durable, lightweight polymer frame and steel internal components, the PS90 is engineered for extreme reliability and longevity. Its design minimizes maintenance requirements and withstands rigorous field conditions.
