Original Item: Only One Available. A lovely example of an M918 Training Practice Round (Cutaway) as used with the e Mk 19 40mm Belt-Fed Automatic Grenade Launcher. 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).

Unloaded or dummy grenades, artillery shell casings, and similar devices, which are cut or drilled in an BATF-approved manner so that they cannot be used as ammunition components for destructive devices, are not considered NFA weapons. This example is in total compliance and is NOT AVAILABLE FOR EXPORT.

When it comes to designing a training program for military personnel, instructors are faced with several challenges. First, unlike athletes there is no off-season, most units are either preparing for deployment, deployed, or refitting from deployment. Secondly, training facilities vary from location to location and often focus on a single task. These tasks may include muscular strength, cardiovascular endurance, field craft or marksmanship. Each of the above contribute to the success of an operation, however there is one area of training that is deficient. This deficiency is visual training; visual ability plays a larger role in achieving optimum performance than most military personnel realize. The goal of integrating visual training into an already packed curriculum is not to dilute it but to improve tactical performance.

To help users better understand the equipment they are using, examples like this cutaway were made. These were intended to give the users a look at the internal structure of the explosives, showing the different layers as well as where they connect or thread into each other.

This cartridge is a target practice round designed to simulate the M430 Cartridge in appearance and ballistics. It is fired from the 40mm Grenade “Machine Gun” Mk 19 Mod 3. It is also used in the Cartridge, Subcaliber Ammunition, Training (CSAT), M970 to simulate the loading and firing of large caliber ammunition.

This cartridge is a fixed round of ammunition consisting of a one-piece steel projectile body which is fitted to a cartridge case assembly. An aluminum ogive, which contains a firing pin plate assembly, a cellular foam anticreep spring, and the standard M550 fuze escapement assembly is threaded to the projectile body An aluminum insert which contains a flash charge chamber is enclosed in the projectile body. A plastic container contains the flash charge chamber which contains one gram of flash charge composition. The projectile assembly is press-fitted into a cartridge case. The case is a hollow bichambered aluminum cylinder with a metal closing plug crimped into the open well of the propellant chamber cartridge base. The propellant in the chamber, which contains the propelling charge, has vent holes in the top and is sealed at the bottom by a closing plug. A percussion primer is crimped into the center opening in the closing plug. The propellant chamber acts as high pressure chamber, and the upper hollow cavity in the case acts as a low-pressure chamber.

This cutaway is a solid example of just how intricate these types of munitions can be. Most markings are still present as is the blue paint. All components are still able to be broken down to better view the internal structure.
