A unique series of Gauss rifles. Developed by ZIVCAS Research Institute based on the chassis of model #62, but with an updated power supply system and power exponent distribution across the accelerator coils. During development, a defect was introduced which caused the Gauss projectile to reach a speed significantly exceeding its structural integrity during firing, resulting in the test stand literally melting in a wave of plasma. The defect was corrected, but it has been taken into account for future development.
