Got my upper today for a featureless build.
And that's when I realized I had gotten an upper with a bayonet lug. "Oops."
I plan to hack off the bottom part of the lug with a dremel in the next day or so. Guessing this will leave a shiny square on the bottom of the FSB. Don't much care about it aesthetically, but want to avoid potential rust issues. What should I put on it?
