I just cleaned my Noveske upper with the usual Hoppes kit, following the standard rules, and I found a small flake of metal on the patch. The rod is nicked a bit, all over, but what are the odds that I flaked the bore or chamber of an N4 barrel with 300 rounds through it? |
| is it brass colored? If it is, I get that too. I think it's from the bullet metal jacket, as it travels down the barrel, it gets some of the jacket shaved off. I don't know that for a fact, but it does it on my too. 700+ rounds so far through my new M&P with no issues. |
| Might be a chrome flake from the gas port hole. Had the rifle been fired before you cleaned it? Normally any debris in the barrel would be gone after one shot. Do you have an aluminum cleaning rod? Were you pushing it from the chamber end? It is possible to carve a divot out of an aluminum rod when pushing it from the muzzle where the sharp ends of the lands are exposed - that's why you push it from the rear. |
