The 40 mm grenade is a military grenade caliber for grenade launchers. A wide variety of 40 mm rounds are deployed including explosive, anti-personnel, smoke, buckshot, flechette and illumination. Originally designed for the M79 grenade launcher – a single-shot, shoulder-fired, break-action grenade launcher that first appeared during the Vietnam War and was referred to as the "mike mike".
In the Cosplay world, recently these have become popular as an accessory to various characters, namely Winter Soldier and Deathstroke.
Replica 40mm M406 Dummy Grenade is made out of solid plastic resin molded from a real inert M406 Grenade and has the same greenish casing and gold metallic finish. They are made to look like the real thing in bandoleers, belts and displays.
They are NOT intended to be used as actual practice rounds or in grenade launchers. These are great for any reenactor, cosplay, or historical display where the real thing is illegal or prohibited to use.
