Highly recommended
Purchased this setup and it worked flawlessly routing my first lower. Once assembled and once your lower is locked into place there's no way it can move, it's rock solid. The end mill is also of excellent quality and showed nosigns of dulling or wear after the lower was completed. The entire process took about an hour but I was taking my time and the end result was a cnc like finish, very shiny and very minimal milling marks.
