80% anodizing question

[Bolts Rock]

I have several sources, one local for hard coat MIL-A-8625 Type III. Google-fu and search have not given a solid answer and neither did ATF.

Is it legal for an FFL 01 or 07 to anodize a lower after machining? Are markings like if manufactured for sale required for said FFL to do this (strictly for personal use, not for sale)?

Note please do not opine on what company procedures may be, what does the law say.

TIA

If kept overnight, I believe they'd need a serial number so it can be logged into their A&D book and out again when you pick it up.

I have trouble with this because there are a lot of pre-GCA non-serialized guns out there that stay overnight to be serviced by gunsmiths. IIRC, there is a proper way for them to log these in and out.

FFL's chime in please.

They can log it in as NSN for "no serial number".

I'm not an expert, but the last time I looked into it, Federally a FFL gunsmith/manufacturer can anodize whatever fits within their paperwork. If you send a machined lower, they should be able to return it to you after the work is done (like sending a firearm out for repair). No marking legally required, but anodizers may have their own opinions.

So following on to this question, what's a good local source for lower type 3 anodizing?
