clamping feed neck(must)
reg if you can afford
I recived this gun as a gift, and i took it out of the box aired it up and dry fired some. It was pretty quiet so i put some paint in it and i was impressed, it was accurate even with the stock barrel.(But a new barrel dose improve the accuracy alot.) So i bought a cp reg and all the upps above and went out to the local feild. This gun really competed with alot of markers out there, but my only problem with this gun i guess is the stock black body it dosnt look that great. But that is not a problem because this is the most custamisable gun out there.
Great beginers gun, cool how many upgrades they have for the gun i do recomend getting alot of them. Overall a very good gun 9 out of 10
Cockers and mags come before the Ion in the way of upgrades. With an Ion you do not want to put a lot of money into upgrades. Get a new trigger, feedneck, on/off ASA, and maybe a QEV and barrel and that's it. Most of the time the stock reg is pretty decent and there's really no regs in that are decently priced that are better.
