the bottom of the two in this picture is going to be the last one I ship since the z channel and holes were the most broken through of the bunch
also worth noting is that it really does not show up as badly as people think, it looks worse because the rails are by themselves and not mounted to a valve, above is a picture of my other mag with back bottle holes and it is quite hard to notice even if I hold my mag by the valve area, which I do quite regularly while walking
