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 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.
