The ARM version is a light machine gun. It has a handle to carry the weapon, a bipod which folds and a larger handguard. The handguard is made from wood. The wooden handguard stays cool when the weapon is being fired fully automatically. The bipod can be used as a wire cutter. The back of the handguard can be used to open bottles. This was put in to stop soldiers opening bottles with the magazines, as this damaged them.
