Is it ok to run a Tactical Machine 80% lower in the white? I have no way to anodize it at this time. I was thinking some aluminum black from brownells- anyone try that? I know anodizing hardens the aluminum, but don't know how critical this is.
What media would I use to blast it in prep for a finish? Thanks! |

I know anodizing hardens the aluminum, but don't know how critical this is. The two main reasons to anodize aluminum are to create a hard layer and provide corrosion protection. The fact that you can also color it is just a side benefit. If you're like most of us, you want to preserve your new work of art. Empty a couple of mags to celebrate finishing your lower, but then get it anodized in whatever way you can. |

I used a buddies milling machine- came out beautiful for my first too. CNC gunsmithing jig
I skipped the process of drilling all the little holes, and just hogged out most of the material with a 1/2 inch end mill then used the template to finish it- much faster that way |
