I cant believe you lapped the anodizing from the metal……. Anodizing provides a corrosion resistance and most of all makes the aluminum surface harder and more wear resistant….. If anything lap before anodizing.. Now it is soft aluminum against hardened steel….. Shaking head…. again and again….
I have these for both AR15 and the AR10, I have yet to find a receiver face that was actually true after anodizing. No matter the brand Aero and Up through LaRue and Bravo Co. All have been off one side or the other. The only thing I do different is I'm anal about any grit getting down in receiver I never want the inside scratched up.
I never saw such a bright, clean and new looking vise.
So stupid.. it's a damn AR
