Could have been a pellet gun.

I would have recommended an OEM replacement, especially if you have glass coverage. Used an aftermarket glass on my old Accord, and the replacement didnt have the exact same curvature as the OEM one did. It was only a tiny bit off, but that was enough that the replacement glass would pinch the upper track molding instead of sliding in under it. That kept it from making a nice tight seal, and let in a little more road noise. It also annoyed the hell out of me everytime I looked at it.
