The lugs on one bolt are getting just a little rounded on the sharp edges. According to USMC TM it would not be a good idea to transfer this bolt to another [well-used?] barrel. How much is too much wear?? 266

ETA: It seems as though the lugs on the barrel assembly hold up much better than the lugs on the bolt.

Next question: Any place to get a good inexpensive one of these?
