Guys, the airzone arrow storm thing is not a different gen arrow storm. They are two different guns and nerf has not sold rights to airzone for the gun to the best of my knowledge. All it is is a blatant rip-off.
A blatant rip-off that is similar enough to be mentioned regardless.
As for the performance differences, I have owned 3 BBB's - 2 purple, 1 red - and the spring in the red one is MUCH weaker. It's saddening.
