The HAZ SAR-21 assault rifle is different when compared to its other counterparts. It is pre-equipped with Extended Fast Mag for both longer firefights and faster reload times, Green Laser Sight for easier spotting in dark areas, Tactical Flashlight for use in dark areas on maps, ACOG Scope for better visibility and range, and Vertical Foregrip for increased recoil control and accuracy.
