Defense Distributed looses appeal to allow distribution of files to build AR receivers

AR in this case is short for AR-15, which is the generic name for civilian (semi-auto only) version of our nations military rifle, originally issued as the M-16 and currently issued as the M4.

"AR" stands for "Armalite Rifle". Armalite was the company founded by innovative weapons designer Eugene Stoner who designed the M-16. As the patents have expired on most of his designs (from the 1950s and early 1960s) many different companies build AR pattern rifles and parts for AR pattern rifles.

The AR "lower reciever" is (as the brief explains) the part of the rifle that has the serial number and is considered the gun by the government for the purpose of various gun control laws. It is possible, with the right tools and plans to build a 100% compatible AR Lower Receiver from scratch.

This is what a commercially manufactured AR-15 lower reciever looks like. All other parts of the rifle are attached to it. The grip, trigger group, butt stock w/ recoil tube, and upper receiver with barrel and bolt assembly.

Apologies in advance if this is not what you were asking. Hopefully someone else reading this article might find it helpful.

Hans the grammar NAZI says it’s “lose”, not “loose”. ACHTUNG!

Make an AK 47 receiver out of a short shovel, and you have the added benefit of the handle as a stock.

Is the appeal now running amuck?

Loses ... Loses (!!!) .... sheesh, now it's even gotten into the headlines!

Here is an "80%" AR lower receiver. The left half in the picture is lacking a deep slot for all the trigger parts and also needs some holes for pins and such. But the bulk of the machining is done.

One can buy a 100% receiver for well under $100. But people invest more in finishing the 80% ones, as there is no paperwork or records involved.

series?!

looses appeal?

this is hugh.

this is hugh.

*laughing* Don't make me send my moose over...

Eugene Stoner's original military rifle was the AR-10. It was chambered in the then-standard NATO rifle caliber of 7.62X51mm which is virtually identical to the .308 Winchester cartridge.

The rifle was adopted by only one NATO country, Portugal, around 1960. It saw use in their colonies in Africa, Angola and Mozambique. Note the brown colored stocks and charging handle inside the carrying handle.

The US Army liked the gun and asked Stoner to scale it down for use by smaller stature Vietnamese troops. The result was the M-16, in caliber 5.56x45mm. Which is now America's longest serving main military service rifle.

Original M16A1 military style AR-15.

Another Eugene Stoner design was the AR-7 survival rifle. It was chambered in .22LR It was also quite innovative - the rifle disassembled without tools and the parts all stowed in the hollow plastic buttstock, which was claimed to float when stored this way. It was created as an emergency pilot survival weapon, where it's light weight was a virtue.

Eugene Stoner died in 1997. Here's his bio on Wikipedia: Eugene Stoner

If that's the moose that bit my sister, tell him to watch his back!

That’s exactly why the encryption program PGP was written _outside_ the USA.
DD should do the same.

That AK build was an EPIC win.

“This wasn’t a big deal, from the BATF point of view — UNTIL cheap 3D printers came along.”

Yeah except that you can get all the machines tools at Harbor Freight cheaper than you can get most 3D printers.

More like they freaked out when LOW SKILL 3D printers came around.

“The DD files made it very simple for an individual to buy receivers that are 80% done, and complete the construction using a small consumer CNC machine. “

While I think this stinks, building an AR through the use of an 80% receiver is easy. You can, if you are careful, complete a receiver with a drillpress, but a small benchtop mill ($700 at a half a dozen places) gives you a functional part that looks just like the commercially machined ones you have to buy through an FFL. Some places that sell 80% lowers also sell “machining jigs” to help you locate all the required features. Everyone should have “his or her own AR!”
And now you can do the very same thing for 1911’s and some of the Sigs.

“I doubt that the target equipment is these 3D printers, which do not produce very strong “printouts.” Driving CAD/CAM equipment seems to be the goal.”

The morons pushing this stuff don’t know anything except what ‘looks scary’. They could not spell CAD/CAM. The CAD/CAM capability for this has been widely available as long as you or I have been alive.

would a moose mose on over

i know they do bite.

hehehe

I doubt that the target equipment is these 3D printers, which do not produce very strong “printouts.” Driving CAD/CAM equipment seems to be the goal.

You can buy polymer AR lowers, so I'm thinking an AR lower from a 3D printer might work OK. If it's not robust, you can make more...

Why don’t they just RELEASE it in Source, publish it in a Book so it can copied and pasted, compiled and wala the proper file is there????

See PGP Encryption.

Can one put the Mattel logo on it? remember the jokes way back when about the M-16 having so much plastic that it must have been made by Mattel Toy Co.
