The CCI Phantom is a Nelson-based pump action paintball marker developed and produced by Mike Casady. Production began in 1987 after about six months of prototype work. The name for the marker was derived from the much more stealth-oriented and drawn-out style of play that was typical when the game was first developing. The Phantom was designed to be powered by a single 12 gram CO2 powerlet, but larger tanks may also be used by removing the powerlet adapter or using a dummy powerlet. When first introduced the marker featured a fixed barrel assembly referred to as a "unibody" combined with a modified Crosman air pistol frame and brass bead sight. However, since roughly 1989 the body and barrel of the marker have been two distinct parts and no longer feature the bead style sight. The marker is also capable of supporting bulk gravity fed hoppers by using a different breech type. The Phantom is one of only a handful of readily available markers acceptable for use in the various forms of stock class paintball. However, because the Phantom is capable of auto-triggering and features barrel porting it is considered to be a "modified stock class" marker.
