I'm cleaning my new LWRC M6A2 rifle after its first time at the range and noticed some wear that looks to of been caused by the bolt, scratches too. Below is a pic where you can see the chipping, is this normal wear? The extractor is in the bolt facing towards the ejection port.

I just remembered that I had a double feed the first time I loaded the magazine into the rifle, that may of caused it. After that, no issues at the range. Figured about as much, and in regards to double feeds and stove piping, When you go to clean the gun the next time around and have the bolt out of the carrier, dry fit the carrier into the upper receiver to confirm that the gas tube is still aligned with the key. With a bad enough case wedge between the bolt and the gas tube, it can bend the gas tube out of alignment. It's really a quick fix at cleaning since you can bank that any bend now of the gas tube is just the portion of it protruding into the upper receiver void, which bending it back at the same location simple and quick as well. |

If your looking to re blacken the bare aluminum spot, then Birchwood Casey Aluminum Black is the ticket.
Although it will not re-anodize (created a hardened coating on the surface of the aluminum), it will re-blacken the bare surface. Just de-lube the small area with acetone on a q-tip, the another q-tip with Alumminuam black on it rubbed into the surface to blacken the small areas. Its a chemical process that etches the bare aluminum surface to blacken, and will not wide off like a sharpie marker would on the next cleaning, nor flake off like a paint that is added. |

I think the scratches may of been caused by the steel bristles on the chamber brush too. Ugh. I remember using the chamber brush a lot during my Army days but don't remember it scratching up in the inside of the receiver, of course I didn't care that much as I didn't pay for the rifle :) |
