Why are complaining about this? this is a small detail. If it was like the major defects like broken canopy and such, ok batty all you want. Obviously you didnt get a MPC. Wanna a see a QC nightmare, get a toynami MPC. Crooked antenna, crappy paint job, floppy leg, etc... Now those are things to batty. Hell it lookes a Bandai with a makeover but the Bandais are still better.
So the moral of the story, when you batty, batty about the major stuff. Better yet, you can always return the 1/48. Or someone here will buy it.
