You Can't Stop The Signal: Homebrew AR-15s

It's an old Firefly axiom:  You can't stop the signal.

Neither can you truly stop or contain the human spirit of innovation or thirst for liberty.  Or of making weaponry.  They often go hand in hand.  To quote George...

"Firearms are second only to the Constitution in importance; they are the peoples' liberty's teeth."
-George Washington

I was once a vocal pro-2nd Amendment net-activist.  Forums.  Letters to Congress.  Petitions.  Memberships in both Gun Owners of America and the National Rifle Association.  Hey, I was young and dumb, and passionate about a cause.

Now, maybe it's a bit presumptuous on my part, but I no longer worry about my guns being taken away.
Register and ban them all you want.  You know why?


I can always make more.

Until they go house to house, smashing lathes and mills, take away people's dremel tools and files, and have thoroughly clamped down on the free exchange of information on the internet, Mankind is always going to have the capability of making implements of self-defense.  The plans are out there.  The genie is out of the bottle.  You can't stop the signal.

Here's a pair of guys who used a Taig CNC mill to construct a pair of lower receivers, which is the central part of an AR-15.  Here's the link to the 6-part series on how they did it

Here are pics of the milled, bolt-together AR lower, from aluminum.

And here are the series of pics of the delrin receiver.

Both builds look to have become .22 Long Rifle pistols, so there's no real worry about too much stress on the lower.

Plans are on

Taig mills and lathes are available through Nick Carter at

A tip of the hat to, where I first found out about this latest effort.

Note that these homebuilds are completely legal here in the US.  Nothing full-auto, nothing in contravention to the myriad and byzantine BATFE regulations.  Semi-auto only.

If you're not trusted by your authority figures with things such as these where you live, maybe you ought to question why, and make your politicians know your opinion.  The Canucks just did.  Or, just buy a CNC mill ;)
