The EMRG-50 Rail Gun was an Arachnoid built rail gun. It boasted a magazine of four shots, and had a minimum range of a hundred meters, and a maximum range of four thousand meters. However, the weapon had a single severe drawback; recoil. The EMRG-50 boasted such a high recoil that it was all but unusable by sentients without a strength factor nearly double that of a standard human. The Arachnoid Ptak-Sok owned a EMRG-50 during the early years of the New Republic.
