Quoted:
If I am properly licensed from the BATF, and I want to build a run of 20 stripped AR lowers, what would I need? And when I say build, I mean starting from nothing. What is the process involved in taking a chunk of aluminum, and turning it into a lower receiver? Are you doing it for profit or for you own personal collection? If your wanting to sell them than you need to be a MFG and if not they can get you for tax evasion. If your just building them for yourself, then you don't need anything; have fun. |

Must make friends with a machinist. Preferably one with access to a CNC machine.

Honestly? From what I can tell you don't know enough about machining or the laws to start. The links provided will give you an idea but please read some more archives and google then, if you are a good study, and after some mistakes, you may have one in a year. That and you would have invested more time and money than most have.
Best of luck. |

I know very little except that I would like to see just how difficult from a manufacturing standpoint it would be to make and sell my own lowers. |

if you split what it would cost you in time and money for equipment you'd need to produce your 20 lowers then you'd pay maybe $4000 a lower,
I would think your best bet would be to approach a current manufacturer and order their lowers with your logo on it... |
