50 rounds on tap in a package that doesn’t make sense—until you shoot it.
The FN PS90 is a compact, bullpup 5.7x28 rifle with unmatched capacity, minimal recoil, and a design that’s decades ahead of its time.

• Barrel: Hammer-forged, Chrome-Lined Ported Muzzle Brake
• Synthetic Thumbhole Bullpup Design
• MIL-STD 1913 Accessory Rail and Back-up Iron Sight

Chambered in the 5.7x28mm cartridge, the FN PS90 utilizes blowback operation and fires from a closed bolt for greater accuracy and reliability. The FN PS90's civilian legal 16.04" cold hammer-forged MIL-SPEC barrel is equipped with an integrated muzzle brake to reduce recoil. Dual magazine latches, cocking handles and an innovative synthetic thumbhole stock with a molded-in sling attachment point help make the FN PS90 fully ambidextrous.

The FN PS90 is the civilian-legal version of FN’s iconic P90 platform, designed for compact handling, high capacity, and exceptional control. Chambered in 5.7x28mm, this rifle delivers low recoil, flat shooting performance, and impressive velocity from its 16.04" barrel.

Its bullpup design keeps the overall length short while maintaining a full-length barrel, making it extremely maneuverable without sacrificing ballistic performance. The top-mounted 50-round magazine feeds horizontally, giving the PS90 its distinctive profile and massive on-board capacity.

Ambidextrous by design, the PS90 features downward ejection, making it ideal for both left- and right-handed shooters. The lightweight polymer frame and balanced layout allow for fast transitions and extended shooting without fatigue.

The Law Enforcement configuration maintains the clean, duty-ready setup with FN’s proven reliability and build quality. Whether you’re adding something unique to the collection or want a high-capacity, low-recoil rifle that stands out from the AR crowd, the PS90 delivers.
