[Source] The 234X augmented spin barrel, also known as the "Penetrator" augmented spin barrel was a model of augmented spin barrel produced by the company Dolmax and sold for File:AurebeshSans-Serif credit.png1750. The barrel increased damage output and armor penetration of any weapon it was attached to but also increased maintenance requirements and downtime due to increased wear and tear on the barrel and frame. Only compatible with blaster rifles and heavy blaster rifles, the attachment was available during the Galactic Civil War between the Galactic Empire and the Alliance to Restore the Republic following the Battle of Yavin.
