Galven barrel

Galven barrels were a type of blaster barrel used in boiler rifles; rifles modified with tibanna gas in order to double their firepower, which burned through galven barrels quickly, meaning the weapons required constant upkeep. In 1 BBY, the Rebel Alliance Special Forces commando Paodok'Draba'Takat Sap'De'Rekti Nik'Linke'Ti' Ki'Vef'Nik'NeSevef'Li'Kek wore four spare galven barrels on each of his wrists while using a boiler rifle during the Battle of Scarif.
