The Ion is an electropneumatic paintball marker manufacture by Smart Parts. At the time of its release, the Ion was the first fully-electropneumtic marker to target entry-level players, at a price point previously inhabited only by Spyders and other mechanical blowbacks. The Ion has generally been credited with making high-rate-of-fire electropneumatic markers available to the masses, at a time when electropneumatic markers were considered out of reach of most causal or budget players.
