what is the purpose of the sections on the left and right of the rail that have the rail milled away and a plastic insert in that area? this is at the front of the rail where the front sight base is. i just cant figure out why they milled the rail away and i have no idea what the black plastic insert is for. thanks.

To allow an M203 to attach to the rifle with the bottom rail removed.
