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?

Easy.

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 www.cncguns.com/downloads.html


Taig mills and lathes are available through Nick Carter at cartertools.com

A tip of the hat to TheFirearmBlog.com, 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 ;)

Wow, that's pretty cool, I had thought of just machining your own lowers. I like the trigger guard on the aluminum receiver too.

If you're ever looking to stock up on stripped lowers, check Brownell's. They've got Spikes Tactical for a ridiculously low $89 bucks each.

There are some great deals on lowers out there, as well as kits, uppers, and even complete rifles.

This post was more for the times when you feel like a DIY receiver is a practical necessity, or a good way to spend a Saturday in the garage/machine shop.

On a Taig no less. I didn't think it was possible. AND he used to dinky little taig vice to do the 2nd side?! If you told me about it without pictures i'd call you a liar.

I'm soooo jealous. The hoops I have to jump through living in Kalifornia make this a pain in the arse.

Bullet buttons and all that crap.

There's an easy solution to that, Mark. Reno's a nice place to live, and only 3 or 4 hours from the Bay Area if you need to get back for something. Lots of machine shops up there that could probably cut some nice molds for your troopers.

You and Vegher need to get out of that business-hostile territory.

Either that, or Franklin Armory sells 10-round PMAGs that are modified with a stud that activates a bullet button for quicker Cali-Mag changes.

This is something my father did before (and after) Vietnam. He did quite a bit of machine work back in the 80's, before CAMs were available for the general public (at least at any kind of reasonable price).

He tried to pull me into it, but it didn't really stick. A shame, really. I enjoy building things with my hands, but I'm no craftsman. Anything I built would be more dangerous to me than my target.

Steven,

Maybe try it again? You never know. The knowledge your dad poured into you might have been germinating all these years in the back of your subconscious.

Also, half the appeal of computer-aided creativity is that the technology smooths out the rough spots and handles the tiny stuff that normally sidetracks manual efforts, enabling you to concentrate more on the result, and less on the means.

Plus, if you screw up, digital changes are much easier to affect than reworking the physical material.

Best,
JBR
