| Newly assy M4 from M&A. Everything looks good, but with less than 100 rounds downrange the Cam Pin shows some distress, or at least I think it does. There is a raised wear mark that matches the contour of the bolt and the BC on the pin. I do not remember this sort of wear from my M16 experience. The wear mark is raised to the point that you can cut your fingernail on it. Is this just a soft, out of spec part or is something else going on here? woody |
