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 Chapman II uses Freon bags in an attempt to cool down the nose-crank, that sometimes would bend on the first Mk V Chapman.
