SP Ion Max'D
Smoke Halo B
48/3000 Crossfire system
A new trigger (must)
anything else it's just optional
It has most of the upgrages that you would do to an normal ion
Trigger, the stock one could be changed too
For a little amount of extra money you get an upgraded ion, you have the 2 pieces freak, the feedneck (the must of any normal ion), the rail with on/off, and a color body kit to match with all of those accesories. The only difference between the new Pro and the Max'D is the body, in both you should feel the improvements far from a regular ion, the consistence of the shooting it's pretty accurate thanks to the barrel, and the other upgrades just make your practice easier.
I believe it's a shortcut for those who are interested in an Ion and are looking for it's upgrades. After purchasing it, you could buy also a new trigger, it's a weakness for a regular Ion, and it's for the Max'D too. A warrior one may be my choice.
Better than an normal Ion, and with more style than an Ion Pro, what else you could ask for? I recommend it.
