Your gun is made of aluminum. No rust unless it's some bizzaro steel clone.
Or are you talking about the barrel? |

only thing I could think of that would rust the door over the ejection port.

I've noticed some rust on the barrel where the front sight base mates with it.
I think it all depends on how you clean and store your firearm. - BG |

Al rust aka al oxide is a benfit to al. No need to worry about it. anodizing is a process that rusts al.
Ferous parts, just keep a light coat of oil on them. |

good morning,
ex-gi here, from looking at all the m16's we had in our armory, you really should not worry about rust. yes, it can rust or oxidize, but keep it slicked up with some good ole clp and it'll be ok. all those scratches add character. these are war rifles! hooah! |

And that all anodizing does is create a thick(er) layer of aluminium oxide. |

Dont worry about it dude, that aluminum is just fine, Now the steel, just keep it cleaned, as long as you clean it and take care of it you wont need to worry about rust.

Most of what looks like scratches is actually on the surface, and can be removed. If you have gouges through the finish and into the actual aluminum, it isn't going to be anything other than a cosmetic issue.
The usual spot for rust on the M16/ AR15 family is in and around the FSB. If you are looking to refinish it just to give it an added level of protection, take a look at Norrells. As long as you have cleaned and degreased, you do not need to break the weapon down. Pop off the handguards and tape your gas tube, and you are all set on the upper. The stock can be pulled off, taped, or refinished along with the rest of the weapon if you want an all matching look (same for the pistol grip). You can probably looking at around $55 to refinish your AR15 yourself, and that is assuming you don't have any of the needed items. Its a very easy process as plenty of people here can tell you. |

You would have to scratch a receiver pretty good to get to bare aluminium. It isn't enough to just remove the phosphate, you also have to scratch through the anodizing, which is pretty hard IIRC.

Guys,
The STEEL parts (barrel, barrel nut, FSB, trigger, FC pins, etc.) are "parkerized" with a manganese phosphate finish. The ALUMINUM parts are hard-coat anodized, and dyed black in the process. Anodizing aluminum is essentially using electrical current to "speed-oxidize" the outer surface of the aluminum, turning it into aluminum oxide, which is a very thin but tough protective coating. Minor scratches are nothing to be concerned about, as the exposed aluminum will re-oxidize and protect itself. Of course, should you ever get MERCURY on your receivers, you're in serious trouble. -Troy |

How does Hg react with aluminum?

If you're worried about the scratches and you actually use your rifle and aren't worried about it being pretty, just spray it with some Krylon and be done with it.

The one combination not to ever use is graphite for a lubricant not only is it too abrasive for aluminum but exposure to salt water with graphite+aluminum=galvonic corrosion..that being said I was up in vermont recently and in a gun shop where an AR displayed on the wall looked like it had been burnt but the furniture was intact.I asked the owner what happened.He said it was stolen 2 months before and recovered from a fresh water pond that happens to be a drain off for cow manure from a local dairy farm.It was taken from the mud at the bottom of the pond bed after at the most 2 months or less and it looked like it was under water in the ocean for like 10 years..all steel heavily rusted and the receivers looked crackled like it had been in a fire...cow crap must have amonia nad other crap in it for that to happen.

I noticed that on both of mine. I don't know how it happened as they were the only ones with rust in my safe, and I kept them oiled pretty well. I used it as an excuse to get them Duracoated in camo. (was getting sick of black only.....added some color). DW |
