The Mk IV SOCOM was the latest Agent-purpose pistol released by MTI. With SemiSmart-nano input as standard, and star-shaped muzzle attachment, the Mk IV is highly sought after by people looking for high firing-rate. The Mk V is exactly the same gun as the Mk IV, but uses Notum alloys instead of standard alloys, which enables additional nano-controlled properties. The Rubi-Ka is the obvious upgrade from the Couji, using separate strings of nano-filters instead of the entwined two-tone ones.
