    My SR556 has about 400 rds through it. No "carrier tilt" just initially wore the finish off the tube lower 1/3 near the pin.
    But I discovered a wear point in the receiver, where the charging handle tip rides. The area is about 1/4 " long (depth of wear = 1/64") just aft of a semi circular cut-out.....
    I doubt the charge handle tip would have caused this....I'm thinking the cut-out is related to the BCG cam pin movement and the cam pin may be the culprit.....but not a mark on the cam pin.
    Any thoughts would be appreciated. I hope the Iphone pix are clear...

    Are you using the stock bolt carrier group?

    Yes, stock BCG & trigger....the charging handle is a Raptor...but nothing on the BCG or charging handle has a mark or wear indicated....I wish I knew what the circular cut, machined opposite the dust cover is....looks like the BCG cam is on the same plain...the wear is just aft of that.
