AR15 Raw Upper -- Interior Surface Finish
I have a raw 7075 aluminum upper. I plan on applying cerakote to the whole rifle. My question is how do I finish the interior of the upper receiver, such that my bolt carrier doesn't just wear it away to nothing.
Any suggestions? Do I have to anodize the whole upper first, then cerakote it?
If I have to anodize it, anyone know of a cheap place around Boston that will do it?

Just cerakote the whole thing. Inside and out. It will be fine.
