It never bothered me but then again I'm not one of those "your opinions are shit, mine are factually correct" faggots that cries whenever they hear something they remotely disagree with. /toy/ seems full of idiots that can't stand the idea of people liking different things.
And with GB's design already being "off" from the official devastator model in many ways, one more tiny thing isn't going to matter. If I wanted a proper Devastator it'd have the goddamn GREEN mixer barrel, not that cartoon purple abortion(like purple if you want but I don't see why anyone pays so much extra cash for Herc or Constructor to have a purple one or calls the green one "wrong"- I will forever prefer toy colors over a budget cartoon and like it when a company makes BOTH instead of "here toon, fuck toy" only). For me NBK isn't really accurate anyway so some small orange bits aren't changing much, if I can live with 40 other inaccuracies I can live with that.
NBK also replaced the dopey gimmicky unfolding drum with one that spins, which I like.
Do buy at least Hook from the Jinjiang KO set though for the big rifle as NBK was too cheap to include one. But don't get the JJ set, it's crap.
