Front takedown pin hole.What are you using as your zero? I've never worked on an 80% lower. Are the holes already partly drilled? I made thousands of lowers, uppers, gas blocks etc at sig sauer when I worked there.

Machine is a Seig X1 micromill that I added steppers controlled by an old computer running LinuxCNC.
