FN PS90 Standard | 5.7x28mm | 16in | 10rd | FN 3848950440

The FN PS90 Standard is a compact, ambidextrous bullpup carbine chambered in 5.7x28mm that combines a synthetic thumbhole stock with downward ejection for unobstructed handling. It uses closed-bolt blowback operation and features a cold hammer-forged barrel with an integral ported muzzle brake to reduce felt recoil. For optics, the Aimpoint PRO red dot sight (priced well under $1,000) is a practical match that preserves the PS90’s close- to mid-range strengths while maintaining fast target acquisition.

Typical applications for this firearm include recreational target shooting and carbine-style competition where compact handling and low recoil are valued.
