The gun had an extremely rapid rate of fire and a moderate spread pattern. It differed from previous repeater models in two critical areas. First, it used metallic bolts similar to those used by the more primitive slugthrowers. Second, it carried an attached concussion grenade launcher, which allowed the gun to fire a concussive explosive.
The heavy repeater was valued by the Imperials for its rate of fire and effective suppression fire capabilities, and was often used for crowd control or to provide covering fire over a large area.
Though intended for use by Imperial forces, this weapon was eventually used by several different groups. It was particularly popular with Trandoshan mercenaries, and it was found in the armory of the Jedi Praxeum.
