For enthusiasts seeking a compact, reliable, and uniquely designed firearm, the FN PS90 stands as a truly iconic and highly sought-after option. Engineered by FN Herstal, a world-renowned manufacturer of high-quality firearms, the PS90 (model 3848950463) delivers an exceptional blend of innovative design, advanced ergonomics, and potent performance. Whether you're a discerning collector, a sport shooter looking for an exhilarating range experience, or someone prioritizing personal and home defense, understanding the capabilities of this distinctive 5.7x28mm carbine is essential.

What sets the FN PS90 apart in the crowded firearms market? Its revolutionary bullpup configuration, ambidextrous controls, and a caliber specifically designed for low recoil and high velocity make it a compelling choice. This firearm is meticulously crafted to provide a lightweight, compact, and user-friendly experience, fulfilling diverse roles from recreational shooting to serious security applications. The unique downward ejection system ensures spent cases never interfere with the user, regardless of shooting position or dominant hand. If you're considering a firearm that breaks the mold while offering proven FN Herstal reliability, the PS90 warrants a closer look.

The Ingenuity of the Bullpup Design: Compactness Meets Capability

One of the most defining characteristics of the FN PS90 is its groundbreaking bullpup stock design. This innovative configuration places the action and magazine behind the trigger group, significantly reducing the overall length of the firearm without sacrificing barrel length. The FN PS90 boasts a substantial 16.04-inch barrel, which is crucial for maximizing the ballistic potential of the 5.7x28mm cartridge, all while maintaining an incredibly compact overall length of just 26.23 inches. This design choice directly addresses the common challenge of balancing maneuverability with velocity and accuracy in a carbine platform.

• Enhanced Maneuverability: The bullpup layout shifts the firearm's weight distribution closer to the shooter's body, creating a remarkably balanced and agile weapon. This makes the PS90 exceptionally easy to handle in confined spaces, during dynamic shooting drills, or when transitioning between targets. For home defense scenarios where space can be limited, this compact form factor is a significant advantage.
• Optimal Barrel Length: Despite its short stature, the PS90 retains a full-length, 16-inch ported barrel. This ensures that the 5.7x28mm ammunition achieves optimal muzzle velocity, contributing to flatter trajectories and impressive terminal performance. The integrated, ported muzzle brake further aids in recoil management and muzzle rise, allowing for faster follow-up shots and improved accuracy.
• Forward-Thinking Ergonomics: The synthetic thumbhole stock is designed for comfort and a secure grip, promoting stable shooting. Molded-in sling attachment points are strategically placed to enhance portability and hands-free carrying, a feature appreciated by both tactical users and recreational shooters moving around the range.

Understanding the 5.7x28mm Cartridge: Performance and Applications

At the heart of the FN PS90's performance lies the unique 5.7x28mm cartridge. Developed by FN Herstal specifically for personal defense and military applications, this small-caliber, high-velocity round offers several distinct advantages over traditional pistol and even some rifle calibers. When users ask, "What makes the 5.7x28mm round special?" or "Is the 5.7x28mm effective for self-defense?", the PS90 serves as a prime example of its capabilities.

Key characteristics of the 5.7x28mm ammunition include:

• High Velocity: The 5.7x28mm cartridge achieves impressive muzzle velocities, contributing to a very flat trajectory and excellent accuracy at moderate ranges. This high velocity also aids in transferring energy efficiently to the target.
• Low Recoil: Despite its high velocity, the 5.7x28mm produces significantly less felt recoil than many other rifle cartridges, and even some common pistol calibers. This low recoil impulse makes the PS90 exceptionally controllable, allowing for rapid and precise follow-up shots. It's a major benefit for new shooters, those sensitive to recoil, or anyone engaging in extended shooting sessions.
• Reduced Weight: The ammunition itself is lightweight, allowing shooters to carry more rounds without an excessive increase in overall load. The FN PS90’s standard magazine capacity of 50+1 rounds is a testament to this efficiency, offering substantial firepower in a compact package.
• Versatile Applications: While initially designed for military and law enforcement, the 5.7x28mm has found a strong following among civilian shooters for various purposes, including:
  • Personal and Home Defense: The combination of high capacity, low recoil, and effective terminal ballistics makes the PS90 a formidable option for defensive roles.
  • Recreational Shooting: Its unique design, low recoil, and distinctive shooting experience make it a popular choice for range enthusiasts.
  • Pest Control: The flat trajectory and effective range can be advantageous for varmint control in appropriate settings.

The synergy between the PS90's optimized barrel length and the 5.7x28mm cartridge ensures a reliable and consistent performance, a critical factor for any serious firearm owner.

Unparalleled Ambidextrous Operation and User-Friendly Features

The FN PS90 is a true testament to ambidextrous design, ensuring that it can be operated efficiently and comfortably by both right and left-handed shooters without any modifications. This thoughtful engineering makes it an ideal choice for households with multiple shooters or for training environments where handedness varies.

• Ambidextrous Controls: Dual magazine latches and cocking handles are symmetrically placed, allowing for seamless manipulation from either side. The ambidextrous safety selector is also easily accessible, promoting safe and intuitive operation.
• Downward Ejection System: A hallmark of the PS90's design is its innovative downward spent case ejection system. This ingenious feature ensures that ejected brass never interferes with the shooter's line of sight or adjacent personnel, making it safe and practical for any shooting stance or environment. It completely eliminates the concern of hot brass flying into the face of a left-handed shooter, a common issue with many side-ejecting firearms.
• Integrated Sighting Solutions and Accessory Rails: The PS90 comes equipped with a non-magnifying optical sight that makes it exceptionally easy to locate and stay on target. This integrated sight offers rapid target acquisition, which is crucial in dynamic shooting situations. Additionally, a MIL-STD 1913 Picatinny accessory rail is integrated into the aluminum receiver, providing ample space for mounting various aftermarket optics, lights, lasers, or other tactical accessories. Back-up iron sights are also included, ensuring reliability even if the primary optic fails.
• Robust Construction: The receiver, crafted from durable aluminum, provides a rigid and stable platform for the action, while the matte black synthetic bullpup stock ensures a lightweight yet resilient structure. This combination guarantees the PS90's longevity and ability to withstand demanding use. The steel barrel, finished in black, complements the overall sleek and robust aesthetic.
