GMG

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).

== Design details == The GMG fires 40 mm grenades at a rate of about 340 rounds per minute. 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 109 cm long and has a 415 mm rifled barrel and a 470 × 160 × 250 mm ammunition box. 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 to be able to compete for United States contracts.
