I purchased an 80% lower receiver paperweight that's designed to use 9mm MP5 magazines. Amongst the things I had to do was make jigs so my machinist vise could hold the receiver. Having a DRO made the drilling and reaming a breeze. The 7/16" 2" length of cut 2 flute endmill was a nightmare. On the other hand, the 1/2" 4 flute corn cob rougher endmill from Amazon was worth its weight in gold!
Was a fun project, screwed up a tiny bit inside the receiver. The sidewalls are .010 to .020 thinner than they should be.
Going to use an 8" barrel. This is going to be my PDW.
Going to save up for a good air compressor and oven. Going to try Cerakoting.
