You may have hit the wrong digit key. The unfinished receivers cannot be more than 80% completed in the situation we are discussing. It is still not an easy job for most people. Most people need a jig to get things right. A milling machine is actually the more appropriate tool but I have a 6” cross slide vice that I have been meaning to do a little work on to get ready to make one of these.
Interestingly enough I did find a supplier selling an 80% completed polymer receiver tonight, which I was not aware of previously. The link I provided previously was to a company which sells an inexpensive CNC milling machine which will do most of the work automatically after you bolt your receiver into it. They are suppose to be

You don’t need a CNC Mill. You can purchase a bench top mill from a number of people (Harbor Freight and Little Machine Shop being two). These mills are all made in China by the same company (SEIG), and with tooling cost less than $1,000. Those folks selling 80% lowers also sell very good fixtures for about $200 that “guide” your milling cutter to properly finish the part. AR15 kits are available that contain everything you need minus the lower. When you are finished with your “personal firearm,” you are into it (minus the cost of the mill) about as much as if you purchased a finished gun.
