It's a very cool design and I don't mean to be rude but there are a few reasons I wouldn't buy one.
1: As mentioned before, it's pretty busy. I don't think anyone would be able to read it off of a vehicle unless it were parked. Even so, they'd need to be pretty close.
2: With all of the colors, it's not going to "fit" onto most vehicles with a single color paint.
3: I don't have any AR's...yet. Any chance of getting an AK on there?
I'd be interested in seeing the design without the flag. No offense here. I'm not anti-flag but that would reduce most of the over color that I mentioned in #2. It would also make it more readable. Also, is there a less modern text that could be used. It seems like it's trying to be an edgy font or something.
Then again, my assessment could be something you're not interested in at all yourself. Just my thoughts. Thanks for reading.
EDIT: Chop a handgun in Lady Liberty's hand and put her behind the firearm overlay. I think that might help a bit
