I would go with the LaRue myself. I got my Ultimate Upper Kit 2 weeks after ordering it and used a lower I already had. It will work with any lower while you wait for one from LaRue if you order it. I have heard and read that Alexander Arms makes good stuff but I personally have no experience with them. LaRue I do have experience with and I don't think you will be disappointed.
