 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.
