I was getting ready to argue the point until I saw the pic you posted, it looks exactly like that, would have never imagined that it came from the factory like that. Thanks
Normal, mine is like that. :?I suspect that what you are seeing is normal. On the side of the flash hider, you will see an area of bright metal. This is where the flash hider is pinned to the barrel.
The first time I saw this, it looked like a defect also.
