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. FN PS90 Standard Blk 10rd 3848950440
