Update on the VG1-5, upper receiver

We have been working on the VG1-5 at a steady pace to try and finish this project. This last week has been spent on the upper receiver. The lathe work has been completed on the upper and now we have started on the operations that have to take place in the machining center. This video shows the actual machining that we did a master cam simulation on earlier.
