About this product

The FN PS90 is a compact bullpup carbine chambered for the 5.7x28mm cartridge. Its design places the action and magazine behind the trigger to reduce overall length while maintaining a full-length barrel, making it practical for range use, close-quarters handling, and general-purpose shooting. The civilian configuration features a cold hammer-forged barrel with an integrated/ported muzzle brake and a synthetic thumbhole stock in Flat Dark Earth. Controls and layout are purposely ambidextrous to accommodate a wide range of users.
