The FN PS90 Triple Rail (TR) gives the operator a wide choice of sighting accessories via its three MIL-STD 1913 rails for mounting optional optical sights, tactical lights and lasers. Chambered in the 5.7x28mm cartridge, the PS90 utilizes straight blowback operation and fires from a closed bolt for greater accuracy and reliability. The 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 olive drab synthetic thumbhole stock with a molded-in sling attachment point help make the PS90 fully ambidextrous. Models with 10- or 30-round polymer detachable magazines are available.
