I'm 99% sure the Nerf Defender is painted.

^ This guy took lots of pictures of the insides of one. Unless you're suggesting they painted the interior surfaces too, I'm sticking with my theory that they're molded in silver and unpainted (except for the dark-colored trim bits, of course).

But like you said, whether it's injection-molding flow trails or paint irregularities, there's nothing to indicate "cracks" in the sense of material weakness or breakdown from the pictures shown, so fire away! It's not going to fall apart on you =)

(OMG, I'd say from that thread linked to above, those things can withstand quite a bit of force, actually!!)
