A while back, I located some 80% AR lowers and bought a couple. I got the taps for the buffer tubes and the drilling jigs. I completed two lowers and gave them to friends, anticipating being able to get more but I can not find a source for them now. The last ones that I ordered were basically a lump of cast aluminum and didn't even have the mag-wells milled out. I have a small mill but it is more work than I want to mill from a solid block of aluminum; does anyone know of another source for 80% AR receivers? Ar15plus.com has them but they cost more than a finished stripped lower and seems a little stupid.
