I'm pretty upset with myself that I hadn't noticed it during the transfer. The gun was still in the box and wasn't assembled yet so I looked everything over but somehow missed that. In hindsight, I should've taken everything out of the box and assembled it but I just didn't want to lose anything. I'll try not to make that same mistake again. I just sent Benelli a repair request with the pictures so hopefully that will help.
I've been trying to determine what could have caused that damage but I think you're right. I guess I'm just one of those guys who is OCD about scratches and dents. Trust me, I wish I wasn't lol.
