Original U.S. INERT M385A1 Training Practice Round For The Mk. 19 & M75 Automatic Grenade Launchers
Original Items: Limited Quantity Available. 40mm grenade is a common design for grenade launcher ammunition. It consists of a low-velocity shell (a grenade) with a caliber of 40 mm (1.57 in). All examples are completely inert in compliance with the current BATF standards on inert ordnance. These 40mm rounds cannot be converted back into a live condition and are Not Available For Export.
NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers like these examples here.
40×53 mm HV (high velocity) is a NATO-standard high–low grenade launcher cartridge meant for mounted or crew-served automatic grenade launchers, such as the Mk.19 AGL, Mk 47 Striker, HK GMG, STK 40 AGL, Daewoo K4 and many more.
The propellant has high pressure and gives the projectile an average velocity of 241 m/s (791 ft/s) depending on the ammunition type.
These M385A1 rounds are an example of the 40mm high-velocity ammunition type. M385A1 is an updated M385 featuring an ogive equal to the M430 HEDP round. The cartridge is designed only for practice or for proof testing weapons. Not authorized for use in the M129 Grenade Launcher.
This cartridge is a fixed round of ammunition. It differs from the M385 cartridge in that the ogive matches the shape of the M430 projectile ogive. It consists of a one-piece solid inert aluminum projectile body together with a metal rotating band which is press-fitted into an aluminum bi-chambered cartridge. The case contains the propelling charge and percussion primer.
It is linked only with the M16A2 link, whereas the M385 is linked with either M16A1 or M16A2 links (no links included). The propelling charge is contained in a spherical high pressure propellant chamber with vent holes in the top. The chamber is sealed at the bottom with an aluminum base plug which is crimped to the base of the cartridge case. The hollow upper chamber in the case acts as a low pressure chamber. A percussion primer is crimped into the center of the case closing plug.
Most of the examples are in similar condition and are free of any extensive damage. Much of the original markings are still present on both the “warhead” as well as the casings.
These are limited in quantity so be sure to act fast to grab an iconic round to add to your collections! Comes more than ready to display.
Mk 19 grenade launcher
The Mk 19 grenade launcher (pronounced Mark 19) is an American 40 mm belt-fed automatic grenade launcher that was first developed during the Vietnam War.
The Mk 19 is a belt-fed, blowback-operated, air-cooled, crew-served, fully-automatic weapon that is designed not to cook off. It 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 can launch its grenade at a maximum distance of 2,212 meters (2,419 yd), though its effective range to a point target is about 1,500 meters (1,600 yd), since the large rear leaf sight is only graduated as far. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its operator, not concealing the weapon's position. For night operation, a picatinny rail quadrant sight can be added for thermal and night vision optics.
The Mk 19A is a man-portable crew-served weapon that can fire from a tripod-mounted position or from a vehicle mount, with the latter being the preferred method, as the weapon alone weighs 77.6 pounds (35.2 kg). The primary ammunition for it is the high-explosive dual-purpose M430 grenade. On impact, the grenade can kill anyone within a radius of five meters, and wound them within a radius of 15 meters. It can also punch through 2 inches (5.1 cm) of rolled homogeneous armor with a direct hit (0-degree obliquity), which means it can penetrate most infantry fighting vehicles and armored personnel carriers. It is especially effective when used against enemy infantry formations. The ammunition comes in cans that hold a 32- or 48-grenade belt weighing 42 and 60 pounds (19 and 27 kg), respectively. Due to its low recoil and comparatively light weight, it has been adapted for use on many different platforms, including small attack boats, fast attack vehicles such as the Humvee (HMMWV), AAV and Stryker, military jeeps, and a large variety of naval mounts.
The Mk 19 automatic grenade launcher replaced the earlier Mk 18 hand-cranked multiple grenade launcher. The 40 mm ammunition used (40×53 mm) is not interchangeable with that used in the M203 (40×46 mm). The M203 ammunition develops a lower chamber pressure, and resultant lower muzzle velocity and range, compared to ammunition loaded for the Mk 19. The Mk 19 fires from an open bolt. The rounds are mechanically fed onto the bolt face with the pull of the charging handles. When the trigger is pressed, the bolt closes, and the firing pin is released. The recoil blows back the bolt, feeds a new round onto the bolt face, which pushes the expended casing off the bolt face.
Production of the Mk 19 is managed by Saco Defense Industries (now a division of General Dynamics Ordnance and Tactical Systems).
In November 2014, General Dynamics entered into an agreement with Advanced Material Engineering Pte Ltd, a subsidiary of Singapore Technologies Kinetics, to manufacture 40 mm high-velocity airburst ammunition for the U.S. military. The 40 mm airburst grenade uses a programmable, time-based fuse that computes and programs the detonation time into it, which counts down once fired to zero to detonate at the intended target point. The airburst ammunition is compatible with the Mk 19, which would give it greater effectiveness and lethality, particularly against concealed and defilade targets.
The U.S. Army plans to introduce several new features to the Mk 19 in an upgrade package that could be introduced by late 2017. Initiatives include: increased muzzle velocity through a less resistant barrel; increased cyclic rate from an improved profile for the vertical cam to reduce the force needed to charge the weapon; enhancing reliability with a redesigned round-positioning block to decrease the chance of misfires; increased durability and shortened re-assembly time after maintenance from a new cocking cam and lever; and an updated mechanical sight utilizing up-to-date ammunition ballistic data to aid accuracy.
