Springfield Armory Saint 5.56mm NATO 16in Black Modern Sporting Rifle - 10+1 Rounds - Introducing new M-LOK compatible SAINT rifles chambered in 5.56mm NATO. These SAINT rifles now feature slim M-LOK compatible handguards from Bravo Company, with an internal aluminum heat shield. California compliant design prevents the magazine release button from being engaged while fully assembled, locking the magazine into the receiver. To release the magazine from the rifle, the shooter will be required separate the upper from the lower by pulling on an extended (rear) takedown pin with an attached cord to make the process easier. Once the magazine has been released the rifle can be re-assembled and shot once again.
