They're apparently on the "Good" list, so they must have done something right to deserve to be on that list.
My only concern is bringing an AEG across the border. I'm going to guess that you're not licensed to bring across firearms, and AirsoftGi doesn't seem to sell weapons with clear recievers. You may run across problems with customs due to that since it would qualify to be a replica firearm at that point (I believe?).
Edit: Damnit Styrak beat me
