receiver

There is so much gasping going around that you can “OMG 3D print a gun”.  Then people go and do shit like this:

A few rounds and it breaks? *yawn* color me un-surprised.  You can check out the full fail breakdown over at Defense Distributed.

I don’t consider myself an expert on the topic of 3D printing, but I have got prototypes made using numerous materials and numerous methods over the years.  3D printing in titanium, cobalt, stainless steel, tool steel, aluminum etc.. have been available for a while, many of which are extremely strong.  People have built everything from impellers to implants using the technology, so making a reliable AR-15 lower using these methods would be child’s play.  Granted, it’s not affordable right now for the average person to print metal at home but you can believe that will be coming.

If guns are ever banned the United States is going to have the most badass type Khyber Pass type gun markets popping up, but instead of half blind people missing fingers making guns by hand with 100 year old tools, you’ll buy your guns from good looking dudes with great hair that kick it in suits all day chilling in high rise condos with a few 3D metal printers.  They will no doubt also have female models answer the phones and greet clients.  My usual whiskey sour while I wait? Sure Rebecca, thanks for asking.

Everyone is jumping on this bandwagon now because of the implication:

Check out Gunsmithing with a 3D printer Part1 and Part2 for the details.

I really hate the phrase “world’s first ______” which a lot of websites are using to describe this experiment.  3D printing is over a decade old, and downloading a firearm related 3D CAD file and feeding it into one of these printers has been done a million times.  The only reason this is making the rounds right now is because of the Aurora, CO massacre. 

“OMG you can PRINT A GUN!” is what people are saying.  So much for gun control if you can just print one, right? *facepalm*Sure the lower is considered the “firearm” as far as the ATF is concerned because it is the serialized part.  The AR-15 lower is such a simple receiver that people have even made them out of cutting boards.  I’ll be impressed when an entire functional firearm is printed, barrel, components, and all.  

Thoughts?

There was some buzz on the internet about this Photoshop I posted in back in 2009:

I don’t remember any company jumping on the bandwagon and actually getting them made in 2009.  Looks like Palmetto State Armory thought it would be a good idea to capitalize on this year’s upcoming November election so they are making some up like the mock-up pictured below:

I’m assuming it’s supposed to be Anti-Obama by the “NOBO12” part of it… but that’s the only giveaway that it isn’t meant to support Obama.  Kind of a fail if you ask me.  The original Photoshop got the point across better.

I really couldn’t care less about “custom” AR-15 lowers with dumb markings on them.  Seems like i’m in the minority on that opinion though, because every time someone says they are going to run a batch anything but “SAFE” and “FIRE” on it, people go nuts.

Thoughts?  Are you a sucker for custom/different fire selector lower receiver engravings?

A classy 3D video animation from CMMG shows us how it’s done:

Do it asap and secure your membership in the AR-15 Builders Club.

The video makes some of the steps look easy as pie… when in reality it’s going to take you a few tries unless you’re a seasoned pro.

CMMG makes a lot of AR-15 related items.  You can check out their website – HERE

That would be priceless if it went down like that between Shia LaBeouf and Tyrese Gibson, but I’m not holding my breath.

The upper receiver looks like an AT4 with some extras. I’m not sure about the night vision.. I don’t know much about those.

  • The upper receiver is a modified AR-15 upper that will feed with standard SAW M249 links
  • The lower and bolt carrier are stock with only a clearance cut added
  • Every other aspect of the gun is standard AR-15

I have no idea if they are for sale.  My guess is that if the price was right (under $300), they would fly off the shelves.  I even think people with regular semi auto AR-15s would buy them for kicks.
