The FN PS90 is one of the most distinctive and compact bullpup rifles on the market, pairing the fast, low-recoiling 5.7x28mm cartridge with fully ambidextrous controls, a 16.04 inch cold hammer-forged barrel, and the proven 50-round top-mounted magazine system that made the platform famous.

Designed around a closed-bolt blowback action for excellent reliability and practical accuracy, the PS90 offers a lightweight, highly maneuverable layout with a synthetic thumbhole stock, forward handstop, bottom ejection, and integrated MIL-STD-1913 top rail. It is an outstanding choice for shooters who want something truly different from the ordinary carbine without sacrificing capacity or control.

For owners looking to take the PS90 platform a step further, we also offer the CMMG 10.4" PS90 Barrel in 5.7x28mm, a purpose-built upgrade for PS90 SBR conversions. It features a 10.4 inch length, 1:9 twist, and M12x1LH muzzle threads for builders looking to bring the platform closer to its original compact footprint.

Need spare magazines? Keep your rifle fed with the factory FN America PS90 / P90 50-Round Magazine, a natural companion for range sessions, defensive setups, or simply having more ready-to-go mags on hand.

To expand the utility of your PS90, add a dedicated under-barrel mount for lights or lasers. We carry the LEVIPS90 4-Slot Under-Barrel Mount and the LEVIPS90 7-Slot Under-Barrel Mount for shooters who want to add illumination or laser capability while preserving the unique handling characteristics of the platform.

The FN PS90 remains a standout rifle for enthusiasts, collectors, and serious shooters who appreciate innovative design, serious magazine capacity, and a compact bullpup layout that still feels futuristic decades after its introduction.
