The Ion Maxd Comes with a custom body kit, Freak barrel with one insert (.693), Q lock feed neck, micro drop, and On/Off bottom line. The Ion is a totally reversionary high end marker. Fist thing is the price you get a high end gun for the price of a mid rang gun. It comes with all of these features  standard.

-- 17 balls per second semi-auto rate of fire with 3 shot burst, full auto and our Rebound firing mode.
-- Break-beam Vision eyes: Reliable and durable, the eyes are mounted on a separate board for perfect alignment.
-- Improved ball detents: Approximately 10 times the service life of current detents.
-- Great efficiency: Expect a reliable 1000-1400 shots from a 68ci, 4500psi bottle without any modifications.
-- The trademark accuracy and range you've come to expect from Smart Parts.
-- Body Kits: A first for paintball. High-end aluminum internals are protected by composite shells--allowing customers to instantly change the color or look of their body. Tired of blue? Switch to red. Or black. Or yellow. The Ion comes in four colors--and there are more body styles in the works...
-- Impulse barrel and feed tube threads: Take advantage of the inventory you already have.  
-- Stock feed tube with O-ring seals: Fits a wider range of hoppers than most guns in this price range.
-- Tools: 1/8" Allen wrench is all you need for primary disassembly--and it’s included, along with trigger and velocity adjustment wrenches and a handy parts kit.
