12508 Posted April 3, 2009 Share Posted April 3, 2009 Hello all, I've noticed some wear or chips on my M4's bolt face. The gun has about 220 rounds through it. It appears that at about the 10 o 'clock and 2 o'clock positions there are some portions where metal has been chipped or worn off. Should I be concerned? Could this weaken the bolt and cause cracks? Here are some pics: Quote Link to comment Share on other sites More sharing options...
