FN PS90 Standard 5.7x28mm 16.04 in 30-Round Black

Description

The FN PS90 Standard 5.7x28mm 16.04 in 30-Round Black is a compact bullpup carbine that brings full-size rifle handling to a 26-inch overall package. Chambered for the high-velocity 5.7x28mm cartridge, it cycles via a blowback, closed-bolt system and ships with a 30-round translucent polymer magazine. The 16.04-inch barrel includes an integrated, ported muzzle brake to tame muzzle rise in rapid strings. Built around an ambidextrous synthetic thumbhole stock with dual charging handles and a full-length MIL-STD 1913 Picatinny rail, this carbine is ready for optics and practical range use right out of the box.

Key Features

• Bullpup Configuration – Shifts the action behind the trigger, giving you a 16-inch barrel in a package shorter than most SBRs. Why it matters: Better maneuverability in tight stages without sacrificing velocity or sight radius.
• Ambidextrous Controls – Dual charging handles and a reversible magazine release accommodate both right- and left-handed shooters. Why it matters: No retraining grip or stance for weak-side transitions in competition or home defense.
• Integrated Muzzle Brake – Ported design vents gas upward to counteract muzzle rise. Why it matters: Faster follow-up shots on steel or paper at speed, especially with the 5.7x28mm’s flat trajectory.
• Full-Length Picatinny Rail – MIL-STD 1913 rail spans the top of the receiver. Why it matters: Mount any optic from a red dot to a LPVO without adapter plates, and co-witness with the included backup iron sight.
• 30-Round Translucent Magazine – Polymer body with clear windows for quick round counts. Why it matters: Fewer reloads in a stage and instant visual verification of capacity.

Who It’s For

Competition shooters who want a flat-shooting, low-recoil carbine for PCC divisions or Steel Challenge. Precision enthusiasts who appreciate the 5.7x28mm’s minimal drop at 100 yards and the bullpup’s balance. Left-handed shooters who need true ambi controls without aftermarket parts.

Pros / Cons

• Pro: 5.7x28mm delivers 2,000+ fps from a 16-inch barrel with negligible recoil.
• Pro: Compact design fits in standard rifle cases and stores easily.
• Pro: Factory 30-round mags are reliable and affordable compared to aftermarket options.
• Con: Trigger pull is heavier and less crisp than aftermarket AR triggers. According to FN specs, the PS90 trigger breaks at roughly 8 lbs, which can feel spongy in precision work.
• Con: Stock trigger and hammer pack limit aftermarket upgrades without significant gunsmithing.

FAQ

Is the FN PS90 legal in all states?

No. The PS90 is a semi-automatic rifle with a 16-inch barrel, so it is NFA-compliant in most states. However, some states (e.g., California, New York, Massachusetts) restrict bullpup configurations or magazine capacity. Check your local laws before ordering. We ship to all 50 states but cannot guarantee compliance with state-level restrictions.

Can I suppress the PS90?

Yes, but you’ll need a threaded barrel adapter or a dedicated PS90 threaded barrel. The factory barrel is not threaded. Aftermarket options from companies like CMMG or TROS USA add a 1/2×28 thread pattern. Keep in mind the bullpup design places the chamber near your face, so port noise is closer to your ear than on a conventional rifle.

What optics fit the PS90 rail?

Any optic with a Picatinny mount works. Popular choices include the Aimpoint T-2, Trijicon MRO, and EOTech EXPS series. The rail has 20 slots, so you can mount magnifiers or backup irons behind the main optic without obstruction.

Does the PS90 accept Five-seveN magazines?

Yes. The PS90 uses the same 30-round translucent polymer magazines as the FN Five-seveN pistol. They are cross-compatible. The carbine ships with one magazine; spares are available separately.

What is the trigger pull weight on the PS90?

Per manufacturer specs, the PS90 trigger pull is approximately 8 lbs. It is a two-stage design with a long take-up. Aftermarket upgrades are limited to spring kits that can reduce pull to around 6 lbs, but the geometry is fixed.

Trust the numbers. According to FN Herstal, the PS90 has been in continuous production since 2005 and is used by law enforcement and civilian shooters worldwide. Over 150,000 units have been sold globally (industry estimate).
