I have a couple of 80% NDS lowers that should be coming back from the engraver soon and then I'll need to mill them out. I'm trying to find out if there's anyone local who can do anodizing. Black is fine. M16 grey would be great as these are retro A1 lowers. I know I can do Cerakote or Norells, and I may have to go that route but thought I'd try this first.
