TAC 80 Polymer Lower: Part - 1

Previously I have made some videos on milling out 80% polymer lower receivers.  Using a drill press, I recently milled another Hybrid80 lower according to their new instructions, which relies heavily on the end mill.  I think overall it is a easier process than the previous instructions put out by Tennessee Arms Company and Hybrid80.  A hour or two on the drill press and you are well on your way to making your own AR-15 / M-4 rifle or pistol.
