Rail Rifle

The Rail Rifle is an automatic weapon used as an assault rifle for ISA troops. Manufactured by Kensington Armaments, the Rail Rifle is the weapon of choice for colonists as well.

Function
The Rail Rifle is a forty five round, fully automatic rifle that is standard issue to ISA front line troops. Instead of using bullets that rely on chemical propellant, the Rail Rifle uses .30 caliber metal slugs that are accelerated to point zero zero zero one percent the speed of light by using a magnetic accelerator to propel the slug down the barrel. While fully automatic, the user can also select fire between a five round burst or a single shot when high accuracy is required.

The weapon's main feature is its ability to discharge all of its ammunition with just one pull of the trigger. This causes the accelerator to discharge all the ammunition left in less than a second as opposed to four in standard automatic. This allows ISA troops making a stand in a cut off position, to lay down withering fire against advancing troops. ISA troops nicknamed this function the Metal Rain Option.

Drawbacks
The Rail Rifle, or the Double R for short, has difficulty penetrating thick armor plating and shields. The weapon is prone to overheating and reports of barrel fatigue and warping are common among troops. This is mitigated by interchangeable barrels however. The Metal Rain Option also has a severe draining affect on the rifle's battery, and thus is used as a last resort option.
