The Stern Defense AR-15 10 inch Assembled Upper Receiver, 8.5 in 9mm Barrel is threaded for 1/2x36. There are a variety of muzzle devices that will fit a 9mm barrel with those threads but you need to decide what kind of muzzle device you want. For example the muzzle brake at the link below would work.
