I just ran into it back a couple of months ago when there was a newspaper report about how dura coat (sp.?) could make real guns look fake (there are a few pics here) as kind of a warning to LEO's and the public. It was accompanied by a pic of a pink glock (sorry glock fans). I can't remember if the hello kitty AR was included in the original or as an add-on later, but yes there are some retards that comment.
There is so much good about the internet, but there is also so much bad with it (anonymity without consequences.) Few people would have the audacity to spout off like they do in the comments if their rear-ends had to cash the check. I just thought it was informative how the guy side stepped all the Cali BS. and still has a reasonably functional AR even if the stock is a bit weird.
