This one appears to be much more durable than any of the others on YouTube so far.

With jack-booted thugs in black, storming into homes where neighbors have snitched on fellow citizens, same as if a citizen made a full-auto version. Some sneaky bleeding-heart gun-grabbing legislator will surly sneak a rider on a federal bill that makes it illegal to manufacture a so-called AW receiver.

Just wait until the anti-2nd Am media gets a load of this.

The problem that has been in previous printed ABS lower is the weakness of the back of the lower where the buffer tube screws into. I notice this version has a reinforcing boss surrounding this area and extending up the side of the lower. Apparently this solved the breakage problem.

Defcad website has not been updated for a few days but as soon as it is I'll wager the files for this current version will be posted and available for download. Please, download the file, put on a disc or flash drive, hang onto it. Keep the genie out of the bottle. Remember, information is freedom.

CAD on new printed lower in center. Note a smaller rear take down pin had to be used, (with a bushing in the upper) to get strength into the design.
