MEI Hellhound (grenade)
 |
The MEI Hellhound 40 mm low-velocity multi-purpose grenade is a fixed-type munition designed to be fired from a 40×46mm grenade launcher such as the M79, M203, M320 (attached to the M16 series of rifles or M4 carbine), or Milkor MK-1. The round consists of an A5 filled metal projectile body with a rotating band, a point initiating-base detonating fuze with safe and arm technology, and a cartridge case assembly. Upon impact with the target, the firing pin is driven into the detonator, which in turn initiates the spit backcharge, producing a jet which initiates the explosive train from the base forward, resulting in an armor-piercing jet of molten metal and fragmentation of the projectile body. The MEI Hellhound uses the same high-low propulsion system as other popular 40 mm grenade launchers, which keeps the recoil forces in line with other infantry small arms.
