Chambered in the 5.7x28mm cartridge, the FN® PS90™ utilizes blowback operation and fires from a closed bolt for greater accuracy and reliability. The FN® PS90™’s civilian legal 16.04″ cold hammer-forged MIL-SPEC barrel is equipped with an integrated muzzle brake to reduce recoil. Dual magazine latches, cocking handles and an innovative synthetic thumbhole stock with a molded-in sling attachment point help make the FN® PS90™ fully ambidextrous. Models with 10 or 30-round polymer detachable magazines are available.
