The R3 was a prototype railgun designed by iTech, which looks to be the future of weaponry in Fareer. It was first issued in 2246 to a Royal Guard troop of the IUR, and worked brilliantly in a few skirmishes. Since then, the IUR has been working on enhancing it to have the capability of Paleogen rifles. It is currently used by many of the elite divisions of the IUR's navy, but has not been mass produced.
The R3 uses a unique system. Unlike most railguns, it has three rails, two for projection and one for ignition. The R3 builds up energy in the core, and the third rail sends it flying fast enough to ignite the air around it, similar to the Paleogenic rifles.
