The Granatmaschinenwaffe (HK GMW) or grenade machine gun (HK GMG) is an automatic grenade launcher developed by Heckler & Koch for the German Army. It fires 40 mm grenades at a rate of about 340 rounds per minute. The GMG is belt-fed, and can be loaded from either side, making it ambidextrous. With a variety of sights available (including night-vision & infrared types) the GMG can be used for accurate, long range bombardments in a large number and types of situations.

The weapon itself is 1.09 m long (the barrel is 415 mm, and the ammunition box has dimensions of 470x160x250mm). The gun operates on a recoil operated blow back basis. It weighs 29 kg; the tripod is an additional 11 kg.

The HK GMG was tested in the Yuma desert in Arizona in 1997 in order to compete for future U.S. contracts.
