Stupid question. I am thinking about getting the 9mm Carbine with the red dot sight. In pictures of this rile it appears to not have a metal front sight. I would like to be able to switch between the red dot and the conventional metal sights. Ghost ring in the rear. Does the version of the rifle with the red dot also come with front and rear metal sights that you can put on? I know, it's a stupid question and the red dot version probably comes both, but I would like to be certain. Thanks in advance to any replies.
