The Relby-v10 mortar gun, also known as the Relby V-10 Grenade Launcher, was a model of blaster rifle/grenade launcher that was used by the Trandoshan bounty hunter Bossk. It was also used by Bossk's father, Cradossk.
Aside from Bossk famously using the weapon, some marksmen of both the Rebel Alliance and the Galactic Empire used the Relby-v10.
