    Default Sending out compleated 80% AR Lower to be Anodized

    I'm in the early planning stages of doing an 80% AR lower build.

    If I wanted to order raw un-coated 80% lowers and do the work to create a functional lower. Could I have it anodized at a local company?

    The issue I am looking at is once its finished its now a firearm and there may be a chain of custody issue if the company that does the anodizing does not have a FFL.

    Or do they even need a FFL in this case?

    Also any recomendations of where I can get this work done in Pittsburgh would be great.

    Just my .02 worth (I too have a raw lower). Why not buy some duracote/cerekote and go all in? At least that's what I am planning

    In any event, there are probably lots of professional services that have all of the proper credentials to get you fixed up

    I can cerakote or duracoat a stripped raw lower pretty cheap if you decide to go that route.

    I am no expert as is well known, but this is what was explained to me.
    Once you complete the receiver all FFL rules apply (unless you butcher it and end up with a useless hunk of metal like I did).
    If the outside surface is already hardened, the interior cavity will still be raw exposed aluminum that is soft.
    People send their builds out to be hardened, but the cost of anodizing the exposed interior cavity is expensive when compared to a budget build.
    You don't need to harden the interior, but the receiver will not be as durable and will eventually fail at the stress points below the pin.

    When I do this I'm going to order a 3 pack of lowers. The best one will be reserved for higher end components and ill be willing to spend the money to get it anodized. Assuming its not not outrageous (like $1000). This is also assuming I don't fuck all three of them up.

    The other two I might go with a lesser/cheaper/DYI solution.

    If I remember right, ballpark to professionally anodize a receiver was about $250, something like that, maybe a bit more.
    I think there was a Poofa guy that posted some prices once, but I could be wrong.
    I never got that far since I Berncly'd my project :0

    As long as it's an 80% lower, which is not a firearm, then they do not to be an FFL to work on it. It's just another piece of metal in the eyes of the ATF.

    I used to anodize small RC parts, all you need is a hot plate and a battery charger.
    Just be careful and make sure it's very clean. It's not that hard to do.

    I dont think you can hard coat anodize at home though.

    Side note, I do not believe anodizing strengthens aluminum, it actually will lesson the fatigue strength a tad.
