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 breach 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. Component Concepts, Inc. (CCI) is located in Newberg, Oregon and was founded in 1979 to provide product design assistance and manufacturing expertise in dental equipment. Operation Compressed gas enters the valve of the Phantom, pressing the cup seal assembly against the retainer with the aide of the valve spring. This gas forces the valve to stay sealed and allows the gun to be cocked which prepares the hammer of the paintball marker for firing. Without the pressure of the gas in the valve the gun cannot be cocked. As indicated by the term pump action the first step in firing the marker is the pump stroke which uses the rod connecting the pump handle and bolt to cock the marker. The pump stroke consists of two parts; the backward pump stroke and the forward pump stroke. On the backward pump stroke the bolt moves back, compressing the main spring until the bolt and hammer are connected by the sear. At this time a single ball drops into the breech. Next, during the forward pump stroke, both the bolt and hammer move forward, chambering the paintball sealing the breech. Next, as the trigger is pulled, the sear pivots and releases the hammer from the bolt.
