Interested in the DD M4.  How is the fit between the upper and lower receivers?

I have 3 Upper and Lower Receivers 2 are complete Rifles and 3rd is waiting on Me to Finnish building. all 3 have a very slight amount of play between Upper and Lower which is correct they were designed that way.
Don't be fooled into thinking that no play at all is good because it is not. I have assembled some that had no play and had to drive the rear take down pin in with a plastic tip hammer. This is not correct fitting and is not a good thing.

DD Lower Receivers have the best Mag Well Flare of any I have seen. Look at one for Yourself I don't think You would be disappointed.
