FN PS90 Standard 5.7x28mm 16.04 in 30-Round Black
About this product
The FN PS90 Standard 5.7x28mm 16.04-inch carbine is a civilian-legal, compact bullpup chambered in the NATO-rated 5.7x28mm cartridge, built around FN Herstal's proprietary blowback, closed-bolt operating system. It delivers the platform's signature short overall length and ambidextrous controls without requiring NFA registration as a Short-Barreled Rifle. This iteration, sold direct from Ironclad Armory, comes with the factory 30-round translucent polymer magazine and full-length Picatinny rail.
What is the FN PS90 Standard used for?
The FN PS90 Standard is engineered for compact, high-volume range use where its 26-inch overall length is advantageous. Its lightweight polymer construction and low-recoil 5.7x28mm cartridge make it exceptionally manageable for extended training sessions, while the integrated rail and optic-ready design support practical marksmanship drills. Functionally, it serves the same role as a compact PCC like a CMMG Banshee but operates on a different mechanical principle.
How does the FN PS90 compare to a Stevens 334 Rifle in .308 Win?
The PS90 is entirely divergent from a traditional rifle like the Stevens 334 in purpose and operation; the Stevens 334 is better for reaching out to 500+ yards with heavier calibers, while the PS90 excels at close-quarters dynamics under 200 yards. Where the PS90 uses a straight blowback action and fires from a closed bolt for reliability, the **Stevens 334 bolt-action** is a turn-bolt design offering superior inherent accuracy for precision shooting. You select the PS90 for its unique ergonomics and low-recoil cartridge, not for its long-range ballistics. You can review our analysis of bolt-action platforms like the Stevens 334 in .308 Win for that discipline.
What does it weigh and what are the dimensions?
The PS90 Standard weighs 6.28 pounds (2.85 kg) unloaded and measures 26 inches (660 mm) in overall length with its 16.04-inch (407.4 mm) cold-hammer-forged barrel. This barrel length yields a 1:9-inch twist rate, optimized for stabilizing lighter 5.7mm projectiles like the 40-grain SS197SR. The compact form factor is its primary geometric advantage, storing more easily than any traditional carbine of similar barrel length.
Who is this NOT for?
This carbine is not for shooters seeking a low-cost plinker, as 5.7x28mm ammunition averages $0.70-$1.10 per round. It's also a poor choice for anyone uncomfortable with the proprietary, proprietary magazine system and the platform's specific disassembly procedure, which differs from an AR-15. If your primary interest is in a traditional, manually-cycled shotgun for sporting clays, I recommend evaluating the Stevens 555 Sporting O/U 12 Gauge instead.
What's in the box?
The factory carton contains the PS90 Standard carbine with one factory 30-round translucent polymer magazine, a user manual, and a chamber safety flag. Ironclad Armory ships it in a discrete, non-descript outer box with all necessary compliance paperwork for your state. It does not include optics, a sling, or additional magazines, which must be sourced separately.
Is the FN PS90 Standard worth it at $1699?
At $1,699, the PS90 Standard is worth it for the shooter who values its unique bullpup mechanics, compactness, and the performance of the 5.7x28mm round above all else. You are paying for FN's military-proven engineering and the tooling to produce this highly specific platform, not for accessory compatibility or cheap ammunition. If your budget is tighter or you prioritize commonality with AR-15 parts, a 9mm AR-platform PCC around $800 will serve you better.

Pros & cons
What works
- 26-inch overall length — shorter than any 16-inch AR-15 by nearly 10 inches
- Weighs 6.28 lbs unloaded — manageable for all-day training sessions
- Full-length 1913 Picatinny rail — provides 13.5 inches of uninterrupted optic mounting surface
- Fully ambidextrous controls — dual charging handles and safety for left- or right-handed use
- Cold-hammer-forged 16.04" barrel — provides exceptional bore life and consistency
Trade-offs
- Proprietary magazine system — magazines cost $45-$65 each and are not cross-compatible with other platforms
- Non-threaded, ported muzzle — requires aftermarket adapter ($80-$150) to mount a suppressor
- 5.7x28mm ammunition cost — averages $0.80/round for practice ammo, nearly triple the cost of 9mm
- Unique disassembly — field-stripping requires specific steps unfamiliar to AR-15 users

Frequently asked questions
- Is it compatible with standard AR-15 triggers or grips?
- No, the FN PS90 uses a completely proprietary trigger pack and has no user-replaceable pistol grip. The entire fire control group is contained within the polymer stock assembly and is not cross-compatible with any AR-15 components. Aftermarket upgrades exist specifically for the PS90 platform but are limited compared to the AR-15 ecosystem.
- Does it fit in a standard rifle case?
- Yes. Its 26-inch overall length allows it to fit in most compact rifle cases designed for weapons with collapsed stocks. I transport mine in a Pelican 1700 case, which has interior dimensions of 36.5" L x 13.25" W x 6" D, with room to spare for magazines and hearing protection.
- How long does shipping take from Ironclad Armory?
- Ironclad Armory typically processes orders and initiates shipping to your selected FFL within 2-3 business days. Transit time then depends on your location and carrier, but continental US delivery usually adds another 3-7 business days. You will receive tracking information once the firearm is shipped.
- Can I return it if there's a mechanical issue?
- Ironclad Armory handles returns only for un-fired firearms with verifiable manufacturer defects, processed through FN Herstal's warranty service. Once the firearm is transferred to you and fired, any issues must go directly through FN's customer service for repair or replacement, which typically has a 4-6 week turnaround for warranty work.
- Does this work with a suppressor?
- Yes, but it requires an adapter. The integrated, ported muzzle brake is not threaded. You must purchase and install an aftermarket threaded barrel or a muzzle device adapter (like those from CMMG or TROS USA) to attach a suppressor. Ensure any barrel replacement or modification complies with the 16-inch minimum barrel length to avoid creating an NFA item.
