Got my first DD rifle today! Liking it very much so far, but have a couple of questions.... One is that the rear take down pin is VERY tight. Had to tap it out a good ways to get it open. Front pin moved under thumb pressure. Is this normal? Also. There is a slight bit of side to side movement between the upper and lower. I know it's normal but has anyone else had this occur on their new DD? Super stoked to get some irons on it and get to the range!
