This weapon is commonly available from Auroran and Rebellion outfitters. It is the only ammunition-fed primary weapon and as such can be a liability in long fire-fights. Try to re-stock as often as possible, particularly when using multiple chainguns, and/or the Storm Chaingun. The weapon is best used to grill small fighters. Taking only a couple of these is not recommended against large vessels, nor is using it for asteriod mining, as the money spent on ammunition will dent your profits.
