What really happens when you anodize over existing anodizing? Does it still have the hardness and just makes it ugly to look at or what?
I built an 80% lower but buggered up the buffer tube hole. Only way to make it work was to permanently attach the buffer tube. Buffer tube has been anodized but 80% lower has not. What can I expect to happen to the tube if I get the whole thing anodized? |

How do you anodize over a layer of aluminum oxide??? |

If the steel lock ring and rear plate (as used on the carbine) and the steel buffer retaining detent and spring are still installed, they will be damaged in the anodizing process. Typically, the anodized part is non-conductive (the anodizing is an insulator) and will not be effected by the process.

Lock ring and end plate are installed so I guess re-anodizing is out. Spot welded the tube to the lower. Ground down the weld and installed the end plate/lock ring.
Forgot to add I also JB Welded the threads for extra measure. I tried red Locktite but it failed to hold when firing. |

If you really want it done still, just send it our way. We can do it for the cost of just a lower and hook you up with the Black Friday 20% off as well. |

I might take you up on the offer. Black Friday price not an issue but I have a new problem.
I used a commercial buffer tube because that's all I had at the time, but none of commercial buttstocks I have work. They all start to go on but then get real tight real fast. Not sure what the issue is yet. Milspec stocks don't even begin to fit. Might have to try a different tube. Yeah won't that be fun taking it apart.

if you anodize an already anodized part but with a few bare spots... it ought to just anodize those bare spots snd not effect the anodized finish. This is granted it was sealed well, preferably with a nickel acetate seal. you will also need to verify it's conductivity on the racking with a volt meter
otherwise it'll need to be stripped which has consequences. it can open up tolerances if over done and tends to show the grain structure (which can look cool sometimes) but is uneven. |
