The Ion is an
electropneumatic paintball marker manufactured by
Smart Parts. The Ion's base parts and design are designed with upgrades in mind; the marker can be altered with aftermarket parts to the point where it can hold its own in today's fast-paced speedball tournaments, or it can easily be made into a competent woodsball marker. The Ion is a very upgradeable gun, it has body kits, as well as after-market replacement parts such as triggers. Smart Parts has also made 2 more recent models of markers, the
Sp-8 and the Epiphany, which use the same or similar internals to the ion.
