Inside the lower where the rear take down pin is has some markings where upper is firm against lower. IS this a problem or does it need to be tight?

I think what you are seeing is scuff marks where the upper and lower are rubbing together. If thats what you are describing it's not a problem. Pictures would be nice.

If you are pressing the pin in with normal thumb pressure no problem.
