The GMG (Granatmaschinengewehr or "grenade machine gun") is an automatic grenade launcher developed by Heckler & Koch for the German Army. It is also often referred to as GMW or GraMaWa (Granatmaschinenwaffe).[1]

Design details[edit | edit source]

It fires 40 mm grenades at a rate of about 350 rounds per minute. The GMG is belt-fed, and can be loaded from either side, making it easy to mount on most platforms. With a variety of day and night sights available the GMG can be used for most medium range infantry support situations.

The weapon itself is 1.09 m long, the barrel is 415 mm, and the ammunition box has dimensions of 470x160x250 mm. The gun operates on a recoil operated blow back basis. It weighs 29 kg; the tripod is an additional 11 kg.

Testing and operation[edit | edit source]

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