    Quality Upper

    Full disclosure I’m a Stern Defense fan boy and think they make the best AR 9 products hands down. The upper reciever is well made and looks great. It paired perfectly with my Wilson lower reciever.

    I purchased this upper receiver and a 9MM mag adapter, spring and buffer so I could shoot 9MM from my pistol. Works great!
