The HX AP-15 is an assault rifle which holds 30 rounds in a magazine. It is carried the most by the members of Blackwater Tactical Team. The suppressed varient has cut down most of the sound and muzzle flash, makes it behaves like M4 in Blood Money, but nearby NPCs will still react to your shooting.
