Scar17 lower loose/rattle

Hello,
Just purchased a new scar17 nrch
Beautiful rifle and everything looks perfect besides the little play the lower has.
specifically where the takedown pin is located. You can move the lower side to side and can hear it rattle a bit.
is this normal on these? If it is, I will just forget about it. It just annoys me a bit. When carrying it by pistol grip, you can also hear, feel it slightly moving.
thanks for help
