Halo M319 Grenade Launcher (grenade launcher)

"The M319 Individual Grenade Launcher, more formally known as the Individual Grenade Launcher, Caliber 40mm, M319, is a single-shot, break-action explosives launcher produced by Misriah Armory and used by the United Nations Space Command, specifically the UNSC Army. Due to its simplicity, ruggedness, and firepower, it has been a mainstay weapon in the Army since its adoption in 2263 and has seen action in several armed conflicts during nearly three centuries of use, with the Human-Covenant War as the most prominent. It proved very effective during the Insurrection; although it is less effective against energy shielded Covenant foes, it can be used to deadly effect against unshielded targets. Because of the weapon's reliability and power, it will likely continue to be fielded by the Army. Sometime after the Human-Covenant War, SPARTAN-IVs used this weapon in a simulation against the Flood aboard the UNSC Infinity. "
