Did you look at your bolt carrier? |

The rear face of your bolt carrier has sharp edges that are causing this cosmetic wear.
You can lightly break the edges by polishing to reduce it. Worth a try. http://www.weaponevolution.com/forum/showthread.php?1744-BOLT-CARRIER-LAPPING-DEBURRING-PROCEDURE |

another possibility to throw out there.

thanks, its definetly sharp edges. i can see where it was scraping the face of the buffer when it closes. and when i close it , it clearly pushes the buffer away form the detent.
looks like i need to clean up the carrier. is this why genuine colt carriers cost more? is there more labor put into them before they ship? not implying the m&a one is junk. it shoots great and was very cheap and quick, im very happy with them. just wondering basically, if i buy a less expesive carrier is this always pretty come to have to do or should i do all my carriers regardless of brand? |
