The PS90 is a compact bullpup platform with a 13.5-inch length of pull and a straight blowback, semi-automatic action. It uses a left-side charging handle and downward ejection through the stock, keeping the overall profile streamlined.
This example is the top-rail receiver configuration with no side rails or integral optic, providing a clean, continuous rail along the top of the housing. The sight/rail housing is cast with "PS90" and "cal 5.7x28," matching the chambering and model designation.
The 16.04-inch barrel is paired with a cylindrical multi-slot muzzle device. The bore is excellent with sharp rifling, supporting the rifle’s 5.7x28mm accuracy potential.
Construction includes a black polymer frame and fixed bullpup stock with integrated sling attachment points, mated to a metal receiver. The top-mounted horizontal PS90/P90-pattern magazine system feeds a 50+1 capacity and is included with the rifle.
Factory markings include "Fabrique Nationale Herstal BELGIUM" on the receiver and "FNH USA FREDERICKSBURG VA." Velcro is adhered to the right side for attaching morale patches.
