I was using a 14" two piece FREAK barrel, my Halo hopper, and my 48/4500 HPA stubby tank whenever I used this marker.
I like the Ion as a back up gun, but it definitely wouldn't be my primary marker. I found the eyes to work better some days, and less so on others (granted, they never failed badly, but there were occasions that I believe were attributed to them).
Taking this gun apart, and getting the bolt out was OBNOXIOUS. I absolutely HATED to use this gun, solely because I knew I'd have to clean it afterwards. The bolt system consists of a few different parts, and is a pain to get it all back together when re-assembling the gun.
This gun isn't terrible on lube, but you always want to be generous; I didn't find it needing lube incessantly.
This gun is pretty loud, so don't count on sneaking up on anyone if you play woodsball.
This guns also eats through air pretty quick. Again, it's not terrible, but it DEFINITELY could be better.
Over all, I'm going to give the Ion about a 7.5 out of 10. If you put money into upgrading the regulator, barrel, and maybe the feedneck, I would give it maybe an 8.5.
If you're looking for a gun of this caliber, I would recommend buying an Azodin Blitz instead. Much better performance, simpler to work with, not to mention cheaper.
8 out of 10
