[Source] The Crusader M-XX was a prototype heavy energy rifle produced by the Black Sun within the Death Watch bunker during the Galactic Civil War, and sold by the Caelli-Merced Syndicate. During 1 ABY, spacers who assisted either the Rebellion or the Empire during the Battle of Restuss and received commendations for their actions were able to requisition this rifle from a factionally aligned Commendation Officer.
