Quantum Industries, located in the Beryus system out near the rim, had a very successful run producing the Fireball 10X. With the first and only miniaturized particle accelerator mounted on top, it blazed a ferocious "fireball" that could destroy virtually everything in it's path. The negative aspect of the relatively slow ramp up/reload time was usually offset by the over efficiency of the first shot. Rumors abound about a soldier who's Fireball 10X overloaded and created a mini black hole which sucked him and the gun into oblivion. This has never been confirmed since there is no evidence left to support the rumor.
