CNC Machine for AR-15 lowers
« on: October 06, 2014, 08:58:15 PM »
I thought this looked interesting for all who have talked about getting an 80% lower.  Currently it is sold out.  If it works, it could be an interesting toy.

Hmmmm   anyone want to go in on getting one? could set up a service, letting people use the machine to make there own,

  never mind, I read the whole thing, Its illegal to allow others to use the machine,

I saw the ghost gunner a little while ago. I want to do a lower, but when they are so cheap, its not worth it.

Unless you are planning on making multiple lowers.  Can't recall the going rate for milled lowers right away (and the sites are blocked here at work) but I believe that at you only need about 5 to break even, right?

Correct. From the FAQ on their site (https://ghostgunner.net/faq.html)

Quote
Is manufacturing a firearm legal?

In general, yes. Semi-automatic firearms, including the AR-15 lower receivers, are generally legal to manufacture for private individuals per US federal law Title 18 do not require serialization or other maker's marks. However, some states/municipalities restrict either the manufacture of certain firearms, or, more recently, the personal manufacture of a firearm with a 3D printer and/or CNC machine. DD makes no claim regarding local manufacturing legality; lower receiver files provided by Defense Distributed might require special licensing to manufacture and/or possess.

Under federal law, manufacturing a firearm for contemplation of future sale without an FFL is prohibited. Without a manufacturing FFL, you should manufacture firearms for personal use only. There are methods to legally transfer ownership of personally manufactured firearms, but they do not apply when the original manufacturing intent is to build a firearm for commercial or non-personal use. Recent ATF determinations have signaled that allowing others use of your CNC equipment may itself constitute manufacturing, therefore Defense Distributed advises GhostGunner owners to neither print firearms for other individuals, nor allow other individuals to use their GhostGunner to manufacture firearms.

However, there's nothing to prevent a group of 5 or 10 friends from all chipping in and buying one together.....

I was wondering about that.  What is the result if 10 people chipped in and bought this thing and then each built their own lowers?

 Ive bought 2 AR-15,s this week off armslist, no paperwork, just cash and show purchase permit. they didn't take info, just wanted to see I had one, seems like a lot of trouble to make your own,

The price of a lower is cheap. A 80% billet is more expensive then a Anderson lower pretty much any where now a days. But for me its a personal thing. I like the fact that it is a lower I "made". I can make it just the way I want it. No company names no roll marks. I can put what ever I for a selector switch, I can truly make it my rifle. I would like to build a SBR out of a 80% lower. If I have to spend the extra coin on a tax stamp I want to make sure it is something that I really like. Kind of silly I know but how often do we do things like this? A lot!

CNC is over rated in my opinion when it comes to a 80% lower. All a person really needs to do it cleanly is a fixture and vertical mill. If a group of guys got together and used the same fixture with a manual machine there is no issue based on MY understanding. They as individuals are manufacturing the lower. CNC gets a red flag thrown up because shots were having build parties were they would charge 20 bucks for you to bring your lower in bolt it down and press run. The individual was not manufacturing anything. He was using someone else code to manufacture his lower. A lot of reading between the lines on this subject but the AFT gets to do that.

Big question is when is BK getting a vertical mill? He needs to expand his machine tools! :)

I have no idea why this is getting air time on news sites.

Go read about the shovel AK47 or something.  Far more interesting.  Far more practical.

Reading about the home made ak47's will also get you into what the legal requirements of manufacturing your own firearms are as well, etc.  IE: when you first bent that piece of metal, stamping, etc.

And home made CNC's can be built relatively cheaply (I'm collecting parts....)... soooo... whatever :D
