Daniel Defense https://danieldefense.com/ just came out with the Ghost Gunner https://ghostgunner.net/index.... that is a $999 mini CNC machine that allows people to make their own AR-15 lower recievers (every other part of the gun you can order and have shipped to your house). This Brownell's link http://www.brownells.com/.aspx... along with a search of youtube will give you all the information you need regarding parts and assembly.
Geeks and Nerds may find it interesting that the site is redirected and secured with SSL by default andpurchases are handled via bitcoin. This suggests DD thinks not just about physical security of it's customers, but their secuirty as a whole.
Given the hardware source is free, this means you can build your own personal armory.
