Thanks for the link to Orion, I'll give them a call.
I got mine from AR15plus.com. https://www.vbd.com/noc/shop/default.asp
I am not really thrilled about the quality but everyone else is out of stock of them at the moment.
They have instructions on the website on how to complete it but basically you just have to drill the holes and ream/thread the buffer tube ring. The jig makes it MUCH easier but theirs is too expensive. CNC Gunsmithing has a cheaper and better jig. http://www.cncguns.com/tooling.html
This whole process is a little more expensive than just buying a stripped lower but I wanted to make an unmarked, partial fence lower and that is the only way to do it currently (without heliarcing or TIG welding).
Now I just need to get repro markings engraved on it and I will be a happy man......
