The Koltso Dredulite Railgun operates by projecting metallic munitions through two parallel rails by electromagnetic rather than chemical force. The conductive capacities of dredulite provide an efficient metal for the electromagnetic circuit of the Koltso, but it remains a heavy weapon preferred by mercenaries rather than a casual defensive tool for drifters engaged in commercial pursuits. While munitions are light and easy to manufacture, the core of the Koltso is the heavy Shavirham battery that ignites the electromagnetic process and can generate up to one hundred and seventeen rounds before it must be exchanged with a new cartridge. Calibrated for the maximum number of charges, the electromagnetic force is strong enough to pierce most suits or even compromise the hulls of light craft from close range. Calibrated for maximum penetration, the charge is strong enough to puncture steel plating from a range of quarter square. This model includes a bulkier barrel modified to allow for increased range over the standard Koltso. Accounts from survivors at the Hotel Gullard massacre agree that the assailants carried Fat Koltsos painted black. This detail - understandably overlooked in most historical records because of the aftermath of the massacre - has lingered in the whispered legends of drifters and led many a bitter strongarm to paint their own Koltso black in solidarity.
