I have a few AR-15 lower receiver setup blocks/drill guides left for sale.  Here is a listing I have on ebay so you can see what they look like.... Item # 3617329165

I am the original designer of these blocks.  They have been tested to work with any mil-spec lower receiver.  You may see somebody else selling a verison of my blocks, and well....THIS GUY HAS STOLEN MY DESIGN!!!  The first week I started selling these blocks, some guy looked at my pictures and tried to copy what I've done.  He may have "copied" my blocks, but he hasn't done the testing and research that I've done with my blocks.  It's sad to think that some people have to copy somebody else's work, because they can't think on their own.  But at least it goes to show what a great product I have for sale.

These blocks are $119 plus $12.95 S/H.  If you are interested or have any questions please email me at [email protected]

Thanks
Justin

Justin has done quite a job, he put out all of the files on his 0% lower build, all of the pics, and CNC program numbers to, if you are lucky to have access to a CNC mill) build your own lower.

You can look at his blocks [url=http://www.roderuscustom.tzo.com/cgi-bin/ib3/ikonboard.cgi?s=3f0c6e240674ffff;act=ST;f=11;t=262]here[/url] and if you follow his 0% build, he did design thses blocks himself.

Just my 2¢ worth.
