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

The GMG fires 40 mm grenades at a rate of about 340 rounds per minute.[2] It 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 is 1.09 m long and has a 415 mm rifled barrel; the ammunition box has dimensions of 470 × 160 × 250 mm. The gun cycles on a recoil-operated blow-back basis. It weighs 29 kg; the tripod is an additional 11 kg.

Testing and operation

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