A MGL, short for micro-grenade launcher, functioned as a portable weapon system designed to launch grenades.
In the era of the Galactic Civil War, the Rebel Alliance maintained a covert operative cell on Coruscant. Within this team, Drokkatta, the Wookiee specialist in munitions, preferred a specific MGL-9 micro-grenade launcher, which he affectionately called "Boomer."
In the time of the Cold War, Guavian Death Gang's security soldiers employed a version of the MGL that was produced by Tostovin Munitions. This particular variant incorporated a drum-style magazine for ammunition. A micro-grenade launcher was also used by Dokar Venas.
