The Relby V-10 Micro-Grenade Launcher is a Special Blaster that doubles as both a blaster rifle using the user's Blasters skill and as a micro-grenade launcher weapon using the user's Explosives skill. It is a long two-handed rifle, with a foregrip for stability and a dual sight atop the barrel. One of these weapons was famously used by the Trandoshan bounty hunter Bossk.
