Legends are never forgotten, classics never die...The CCI Phantom Pump Paintball Marker w/ M16 Grip has been in production for over 20 years for one simple reason. It is one of the greatest marker designs of all time ! Lightweight, simple yet rugged design and notorious accuracy are its hallmarks. Pump paintball play has seen a resurgence that is here to stay. Some pump players are veterans returning to their roots. Many like the challenge of limited firepower, preferring to make their shots count and being the underdog. Others play pump for the economy of being able to play more often by shooting less paint. When you need to pump the marker to cock and load each shot your paint money goes a lot farther. Whatever your reason for playing pump, there is a Phantom to fit your needs !Stock Class emulates the original paintball marker action. Powered by 12 gram CO2 cartidges, the magazine holds 10 rounds and is horizontal to the barrel. The marker must be titled as it is pumped to charge the marker and chamber each ball, otherwise known as "rock 'n' cock".
