ammunition belts: either the American disintegrating M13 linked belt (NATO standard) or the non-disintegrating segmented German DM1 belt, whose 50-round sections can be linked through a cartridge. The DM1 belt is based on the last version of the Gurt 34/41-family used in World War II in MG 34 and MG 42 machine guns. After firing, the separated M13 link or emptied DM1 belt section is cleared out on the right side of the receiver through an ejection port normally covered by a spring-loaded dust cover. In order to adapt the weapon to feed from one belt type to the other, several components of the feed mechanism need to be reconfigured since the position of the feed tray's cartridge stop and pawl angles in the top cover are different. The MAG features a pawl-type feeding mechanism that continues to move the feed link during both the rearward and forward cycles of the reciprocating bolt carrier, producing a smooth belt flow. The feeding mechanism's three pawls are actuated by a roller connected to the bolt carrier. The feed channel rail, feed link, both feed slides and the feed tray are chrome plated. The top cover body is an anodized aluminum casting. In the infantry assault role, the weapon can be fitted with a sheet metal container that houses a 50-round belt and is attached to the left side of the receiver. Sights The MAG is equipped with iron sights that consist of a forward blade (adjustable mechanically for both windage and elevation) and a folding leaf rear sight with an aperture in the down position for firing distances from in increments and an open U-notch for ranges from graduated every . The rear sight is hinged to a base with protective ears that is integral with the receiver's upper forging. The iron sight line has a sight radius. The top of later production model receivers often feature a MIL-STD-1913 rail as a mounting platform for firearm accessories like (low light) optical sights and night-vision devices. Safety With the safety placed in the safe setting, the sear mechanism is disabled. The safety can only be engaged with the weapon cocked. Bipod and tripod For the light machine gun fire support role, the gun is fitted with a folding bipod (attached to the end of the gas cylinder) that can be adjusted for height. For carrying or use as a forearm, the aluminum legs
