Sebastian and a friend have described in detail their latest successful attempt at making an AR-15 lower at home. They used a CNC mill to machine the lower out of a block of Delrin.

Neither of the pair were machinists. Anyone with enough motivation can learn how to make an AR-15 at home. If you can’t afford a CNC mill, you could always build one yourself.
