The MK19 40mm machine gun is an air-cooled, disintegrating metallic link-belt fed, blowback operated, fully automatic weapon and is crew transportable over short distances with limited amounts of ammunition. It can fire a variety of 40mm grenades. The M HEDP 40mm grenade will pierce armor up to two inches thick, and will produce fragments to kill personnel within five meters and wound personnel within 15 meters of the point of impact.
It delivers a heavy volume of accurate and continuous firepower against enemy personnel and lightly armored vehicles.
The MK19 can mount on a tripod or on multiple vehicle platforms. It is the primary suppressive weapon for combat support and combat service support units. The weapon can protect motor movements, assembly areas, and supply trains in bivouac. The MK19 Grenade Machine Gun can defend against hovering rotary-wing aircraft, destroy lightly armored vehicles, fire on suspected enemy positions, and provide high-volume fire into an engagement area and indirect fires from hidden positions. The system increases the capability of U.
Glad you asked. Just remember to use a bullet-less round, aka a blank, or a grenade with a bullet-trap…. Photo via Wikimedia Commons. The earliest serious incarnations were rifle grenades, which were exactly what they sounded like: special charges meant to be mounted on the business end of your rifle barrel and shot off, at five times the range of their handheld counterparts.
A rifle grenade could be fired in a plunging arc overhead, and unlike other indirect fire weapons like mortars or artillery, they could go wherever a rifleman went — anywhere — as this edition of Popular Mechanics notes. Say what you will about the munition, the name is pretty accurate…Popular Mechanics screenshot via Google Books.
Grenade Launchers , Gordon L. The program was called Project Niblick — named after a 9-iron golf club , to highlight the similar arcing trajectories of a golf ball and a grenade in flight, according to Rottman. By , Project Niblick had its ace in the hole: the 40mm grenade. The idea was a weapon that could lob a high explosive munition up to meters — though the effective range for most launchers comes in at around meters, or less — and with no more recoil than a gauge shotgun.
The break-action shotgun-style launcher was officially approved by the military in and immediately began making its way into the hands of U. But it only fires one round at a time. The military had also tested out the T, a semi-automatic grenade launcher that could lob three rounds in the air before the first hit the ground. After minimal field testing, that prototype got scrapped in Grenades launched from a rifle could reach perhaps m yd , but still lacked an effective sighting system and had to be braced into the ground for firing.
They could not be fired from the shoulder due to punishing recoil, which limited their usefulness in the attack. They also wore out the barrels and cracked the stocks of the rifles used. One solution was to develop a dedicated grenade launcher weapon. Engineer Arnold Louis Chevallier immigrated to Britain prior to the War and came up with a wholly new design. The rear half of the launcher comprises a Martini tilting-block action previously used by the British army in the Martini-Henry and Martini-Enfield rifles.
In this case, a commercially produced. The rifle's barrel was replaced by a large barrel of 6. This featured retaining clips at the muzzle and a sprung piston platform at the base. The grenade would have been launched by a. The Blanch-Chevallier was never issued. In fact, there is no evidence to suggest that it was even trialled by the British War Office. Instead, they persisted with improved rod grenades and repurposed a much older solution in the form of the grenade cup discharger, introduced in as an accessory for the SMLE rifle.
It is not possible to evaluate the effectiveness of Chevallier's design, but two drawbacks are evident. Firstly, to soak up the recoil of firing, it had to be extremely heavy, and a supply of grenades would have added to the weight. This would have made the carrying of a rifle impossible, though a revolver could have been supplied for close-range fighting and self defence.
Secondly, the weapon as constructed could not load the standard No. It would have required either that Britain tool up for production of its proprietary grenade, or that the weapon be redesigned to accept an existing type.
Due to a lack of safety features, it would also have to carried without a blank cartridge in the chamber.
