Doing a clean & lube before shooting my New AR 556, Notice the bottom of the muzzle flash is off center from the barrel. I ran a wooded dowel down the front and back of the barrel and it seems to straight. Should I be concern about it.
Another thought, is it timed just past or just before being centered with regards to tightening it? If just before, you might be able to align it, if just past, remove and add a peel washer between the crush washer and the flash hider.
