Weight
Weighing in at precisely 6.28 lbs (2.85 kg), FN Herstal’s PS90 rifle achieves remarkable weight efficiency through its polymer construction and bullpup configuration.
You’ll find this civilian legal version slightly heavier than its P90 PDW counterpart, which tips the scales at 5.8 lbs. The unconventional bullpup design maintains an 18-inch barrel while keeping the overall package exceptionally manageable and maneuverable.
Barrel Length
Meeting federal regulations, the PS90’s 18-inch barrel configuration incorporates a permanently attached shroud that extends the overall barrel assembly to comply with U.S. civilian firearm requirements.
While the P90 was designed with a shorter barrel, the PS90’s cold hammer-forged 18-inch barrel ensures legal compliance while maintaining functionality. You’ll find the closed bolt design and trigger mechanism work seamlessly with this barrel length, though it slightly reduces the 5.7x28mm round’s ballistic performance.
Material Made Out Of
Constructed primarily from lightweight polymer composite materials, FN’s PS90 achieves a remarkably low weight of 6.28 lbs while maintaining structural integrity.
The design incorporates a durable alloy upper receiver and sight bridge, while the thumbhole stock integrates synthetic polymer components.
The 16.04-inch cold hammer-forged barrel, combined with polymer and metal hybrid internal components, delivers optimal performance while minimizing weight.
Chambered In
The FN PS90 rifle chambers the proprietary 5.7x28mm cartridge, a high-velocity round specifically engineered by FN Herstal for enhanced penetration capabilities.
The cartridge’s polymer-coated brass case ensures reliable cycling through the FN PS action while delivering minimal recoil. Even with the rifle’s 16-inch barrel configuration, you’ll achieve optimal ballistic performance, maintaining the round’s intended velocity and terminal effectiveness.
Capacity
When considering magazine specifications, standard PS90 rifles feature an impressive 50-round capacity in their unique horizontally-mounted magazine design. U.S. civilian models comply with state regulations through restricted 30 or 10-round magazines.
However, aftermarket adapters enable increased capacity back to 50 rounds. This substantial ammunition capacity allows for sustained fire capability during tactical operations without frequent reloading interruptions.
Trigger Pull
Operating with mechanical precision, the PS90’s trigger system delivers a smooth, consistent break at 5-7 pounds of pull weight. You’ll notice minimal overtravel and a short reset distance, enhancing your trigger discipline during rapid follow-up shots.
The bullpup configuration positions the trigger mechanism forward, providing ergonomic control that sets it apart from conventional rifles. The PS90’s responsive trigger outperforms many competing bullpup designs.
Safety?
Located inside the trigger guard, FN’s ambidextrous safety switch provides intuitive control while maintaining the PS90’s streamlined profile. The ambi safety integrates seamlessly with the rifle’s closed-bolt system, offering an additional layer of security when handling this 6.28 lb firearm.
This strategic placement ensures quick access while operating the high-velocity 5.7x28mm platform, regardless of your shooting hand preference.
Action
The FN PS90’s semi-automatic action pairs a closed-bolt design with downward ejection, creating a streamlined operating system. You’ll find the reciprocating mechanism efficiently cycles each 5.7x28mm round while maintaining accuracy through its closed-bolt operation.
The integrated muzzle brake works in conjunction with the action to minimize recoil forces, ensuring consistent shot placement and rapid follow-up shots.
Optic Ready?
When mounting optics on your PS90, you’ll find a full-length Picatinny rail integrated directly into the receiver’s top surface. The rail system accommodates both low-profile and full-size optic mounts without any modifications needed.
Optic compatibility extends to various non-magnified reflex and red dot sights. You’ll achieve a stable, consistent sight picture for precise target acquisition and accurate shot placement.
Picatinny Rail?
Building on the optics mounting system, PS90’s integrated Picatinny rail follows MIL-STD-1913 specifications with precise dove-tail angles at 45 degrees and uniform slot spacing at 0.206 inches.
The aluminum rail, machined directly into the receiver’s top surface, provides you with a rigid platform for mounting accessories. You’ll find this standardized interface allows secure attachment of various optics, from red dot sights to tactical scopes, enhancing your PS90’s versatility.
Review
The PS90’s advanced ergonomics and low recoil make it a top choice for home defense and competitive shooting, though you’ll need to weigh this against its higher ammunition costs and limited availability.
You’ll find exceptional reliability from its proven delayed blowback system and hammer-forged barrel, with failures being extremely rare when using quality ammunition and maintaining proper cleaning schedules.
The rifle’s popularity among law enforcement, security personnel, and civilian sport shooters stems from its compact size, ambidextrous controls, and the armor-penetrating capabilities of the 5.7x28mm round.
