New Mossberg 500 in 12ga. Fired about 100 rounds through it and when cleaning, noticed the receiver has a gouge in it, in the channel where the bolt rides. The scratch is at the top, toward the very rear just in front of the safety. It would appear this is coming from either the firing pin retaining pin, or the sloped portion at the top rear of the bolt.

I do not think this is normal wear, as it is only occurring on one side of the little machined slope. Anyone else experience this? Been searching all day and only found a few similar problems, hoping I can replace a part instead of mailing the whole thing to the manufacturer.
