I need help finding a site.  There was a site with pictures and cadd files for an ar lower you could bolt together.  If anyone has a link or remembers where it is, could you post it here?  Thanks

The guy that built the "bolt-together" AR lower was "user556". He used to post here but I haven't heard anything out of him in quite a while. His site is still up, however.  

Here's the link to the main site Tabletop Machining.

Click on the heading P6: AR15 Receiver under "Projects".

I don't believe that he ever actually posted the CAD drawings on his site. They are, however, posted in the Library section over at the Roderus Custom Guns forums.  To get the drawings, click here, RCG Forums, and go to the "Information Exchange". I believe they are in the "Blueprints" section, or just check the "Index".

Interesting project.
