The Mk 19 Grenade Launcher is a belt-fed automatic 40 mm grenade launcher or grenade machine gun that entered U.S. military service during the Cold War, first seeing action during the Vietnam War and remaining in service today.
Overview
The Mk 19 is belt fed, blowback operated, air cooled, crew served, fully automatic weapon that is designed not to cook off.
The Mk 19 fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 is able to lob its grenade at a maximum distance of 2,212 meters, though its effective range for a point target is about 1,500 meters, since the large rear leaf sight is only graduated to 1,500 meters. The nearest safe distance to launch the grenade is 75 meters during training. In addition, the Mk 19's flash suppressor and its lack of smoke during firing makes it difficult for enemies to spot and counter it. For night operation, an AN/TVS-5 night vision sight can be fitted.
