It hasn’t been a problem but I noticed a nice scratch in the bolt that happened the first time I removed it to clean it. My thoughts are that it came from a sharp edge on the receiver, either the long opening for the charging handle, or one of the stock pin holes? IDK. It’s this bad? It’s not getting worse. Should I check the next time I have it apart and sand off file any burrs if any?
Thanks in advance!
