Pull your bolt Carrier System out. See if there is some burrs on the top of the carrier. If you cant see any the paint the worn area with a marker and reassemble. Cycle the gun 100 times and see if the area gets rubbed again, if it does then the carrier nose may be bent, the receiver may be out of spec, or the bolt may be jumping off the rails it when its at the rear (Somettimes a thin buffer helps eliminate this if you dont have finds for a new receiver)

Give it a try and report back.

That is at the front of the cover isn't it (looking at the ejection port on the top of the pic).
