Yep, what to do about this, if anything? The dent is small and just below the shoulder. My concern is that it will affect the reloading of said brass. I get a dent in my .45 brass from my full size Kimber buy after sizing/decapping you can hardly see it and it doesn't seem to affect the reloads. I was impressed with this AR from Curt's because it throws the brass slightly back and in a real small area. Small especially compared to my hand guns. Thinking of putting a piece of mole skin on the little deflector nub on the upper.
