Chambered in the 5.7x28mm cartridge, the FN PS90 utilizes blowback operation and fi res from a closed bolt for greater accuracy and reliability. The FN PS90's civilian legal 16.04in 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. --- ## Product Details - Caliber: 5.7x28mm - Magazine: 10 - Operation: Closed bolt, blowback - Barrel Length: 16 in - Stock Color: Matte black
