Specifications
You’ll find the PS90’s specifications reflect FN Herstal’s commitment to compact firepower and ergonomic design. The rifle’s lightweight polymer construction keeps handling nimble while maintaining structural integrity for reliable operation. These key specifications determine the PS90’s performance characteristics and suitability for your intended applications.
| Specification | Value | Details |
|---|---|---|
| Weight | 6.28 lbs | Lightweight synthetic construction |
| Barrel Length | 16.04 inches | Integral muzzle brake included |
| Material | Synthetic polymer | Matte black thumbhole stock |
| Chambered In | 5.7x28mm | 1:9 inch twist rate |

Weight
At 6.28 pounds, FN’s PS90 rifle achieves remarkable weight efficiency through its innovative bullpup configuration and material selection.
You’ll find the alloy upper receiver and synthetic thumbhole stock significantly reduce overall mass while maintaining structural integrity. This lightweight design enhances portability and maneuverability, making it ideal for personal defense applications where quick handling and reduced operator fatigue are essential.
Barrel Length
While conventional rifles sacrifice portability for ballistic performance, the PS90’s 18-inch barrel delivers an optimal compromise between legal compliance and terminal effectiveness.
The bullpup configuration positions the barrel within the receiver assembly, creating a compact design that maintains maneuverability without excessive ballistic degradation. This barrel length satisfies U.S. legal requirements while preserving the 5.7x28mm cartridge’s intended performance characteristics.
Material Made Out Of
The PS90’s construction materials represent a careful balance of weight reduction and structural integrity. You’ll find the upper receiver and sight bridge crafted from lightweight alloy, while the barrel utilizes cold hammer-forged MIL-SPEC steel for maximum durability.
The metalwork composition combines these metals with a synthetic thumbhole bullpup stock, creating optimal strength-to-weight ratios for reliable performance.
Chambered In
Since FN Herstal designed the PS90 specifically around their proprietary 5.7x28mm NATO cartridge, you’ll experience superior armor penetration capabilities compared to conventional 9mm or 5.56x45mm rounds. The bottleneck cartridge features polymer-coated brass cases for reliable feeding and produces minimal recoil for enhanced target acquisition.
However, ammunition cost averages $1.00 per round, significantly impacting operational expenses.
Capacity
Beyond ammunition considerations, magazine capacity directly impacts your tactical effectiveness with the PS90. The rifle’s standard configuration holds 50 rounds, though commercially available magazines are limited to 30 or 10 rounds.
You can restore full capacity using a Spring Plate Adapter. This high magazine capacity eliminates frequent reloading, providing sustained firepower advantage over compact firearms.
Trigger Pull
When engaging targets with precision, you’ll encounter the PS90’s notably heavy trigger pull weighing 8-10 pounds—significantly heavier than most semi-automatic rifles. The trigger exhibits long, creepy take-up with gritty break characteristics, compromising accuracy and control.
This complexity stems from the bullpup design’s intricate mechanism. Fortunately, aftermarket trigger improvement options exist to enhance pull weight and overall feel.
Safety?
How does the PS90 prioritize shooter safety through its design specifications? You’ll find the crossbolt safety above the trigger guard enables ambidextrous operation. The semi-automatic action requires deliberate trigger pulls for each shot.
Its bullpup configuration keeps the muzzle downrange, while closed-bolt operation prevents accidental discharge. The muzzle brake enhances control during training practices, reducing recoil-induced safety risks.
Action
The PS90’s semi-automatic action fires one round per deliberate trigger pull, utilizing a straight blowback operating system powered by the 5.7x28mm cartridge’s recoil energy.
You’ll find the closed-bolt design enhances accuracy through consistent firing mechanics. Ambidextrous operation is facilitated by dual charging handles, allowing manipulation from either side.
The trigger mechanism’s complexity requires proper maintenance for reliable function.
Optic Ready?
While FN Herstal equips the PS90 with an integrated non-magnifying optical sight for both-eyes-open shooting, you’ll find enhanced versatility through the rifle’s Picatinny-style rail system mounted on the upper receiver. This optic compatibility allows various sight attachments based on your tactical requirements.
The PS90 Tactical variant supports visible or infrared laser integration, maximizing your operational flexibility.
Picatinny Rail?
FN Herstal integrates a full-length Picatinny rail system directly into the PS90’s aluminum alloy upper receiver, providing MIL-STD-1913 compatibility for secure optic mounting.
You’ll find this durable rail accommodates various sight options including red dot sights, magnified scopes, and tactical accessories. The integrated design ensures proper zero retention while offering complete customization flexibility for your specific operational requirements.
Review
When evaluating the PS90’s performance characteristics, you’ll find distinct advantages in its ergonomic bullpup configuration and exceptional accuracy capabilities, though you must consider the trigger complexity and ammunition cost factors.
The rifle’s reliability stems from its closed-bolt operation and robust construction, making it suitable for law enforcement agencies, security professionals, and civilian enthusiasts seeking a unique platform.
You’ll need to weigh the PS90’s innovative design benefits against practical considerations like specialized accessory requirements and 5.7x28mm cartridge availability in your local market.
