Carbon build up on the crown
#4
Looks like your brake isn't sitting square to the crown face.

When I pull my brake or flash hider off its a nice even star pattern in the carbon build up.

I haven't noticed any degration of accuracy in my rifles due to it but I will keep a log on it now to see if I can find a pattern to it.

I typically clean the crown bout every 500 rounds when I do my 500 round tear down for cleaning and maintenance.
