New product from Modulus Arms

This makes the drilling portion of completing an AR 80% receiver go much faster and easier. Especially for those using a hand drill or small drill press.
Drilling a 1/4" pilot hole first instead of just trying to just blast through with a 3/8" from the git go, makes a huge difference
