I was thinking the same thing. I might tear it down myself, but I just got it yesterday, not even 24 hours ago. Now... the display being crooked is something of extreme importance. My OCD about that kind of thing is greater than the 510 which I really only notice when switching toppers@Infinite1 I have pretty much the same thing with my 510 but it depends on which atty I use. Some work better than others. It does feel loose but I think it is what was used in all the g2 mods.
I am sure youtube videos will arise on changing a 510 in a g2.
